Detailed Description

Class representing the state of a single texture unit during a Pass of a Technique, of a Material.

Remarks
Texture units are pipelines for retrieving texture data for rendering onto your objects in the world. Becode Ogre-Next no longer supports the fixed-function pipeline, some of the settings (e.g. setting a texture rotation) will only have an effect if the shader applies receives param_named_auto texture_matrix as input and multiplies that matrix against the UVs to apply these transformations.

◆ removeEffect()

void Ogre::TextureUnitState::removeEffect ( const TextureEffectType  type)

Removes a single effect applied to this texture layer.

Note
Because you can only have 1 effect of each type (e.g. 1 texture coordinate generation) applied to a layer, only the effect type is required.

◆ retryTextureLoad()

void Ogre::TextureUnitState::retryTextureLoad ( )
inline

Tells the unit to retry loading the texture if it had failed to load.

◆ setAlphaOperation()

void Ogre::TextureUnitState::setAlphaOperation ( LayerBlendOperationEx  op,
LayerBlendSource  source1 = LBS_TEXTURE,
LayerBlendSource  source2 = LBS_CURRENT,
Real  arg1 = 1.0,
Real  arg2 = 1.0,
Real  manualBlend = 0.0 
)

Sets the alpha operation to be applied to this texture.

Remarks
This works in exactly the same way as setColourOperation, except that the effect is applied to the level of alpha (i.e. transparency) of the texture rather than its colour. When the alpha of a texel (a pixel on a texture) is 1.0, it is opaque, whereas it is fully transparent if the alpha is 0.0. Please refer to the setColourOperation method for more info.
Parameters
opThe operation to be used, e.g. modulate (multiply), add, subtract
source1The source of the first alpha value to the operation e.g. texture alpha
source2The source of the second alpha value to the operation e.g. current surface alpha
arg1Manually supplied alpha value (only required if source1 = LBS_MANUAL)
arg2Manually supplied alpha value (only required if source2 = LBS_MANUAL)
manualBlendManually supplied 'blend' value - only required for operations which require manual blend e.g. LBX_BLEND_MANUAL
See also
setColourOperation
Note
This option has no effect in the programmable pipeline.

◆ setAnimatedTextureName() [1/2]

void Ogre::TextureUnitState::setAnimatedTextureName ( const String name,
unsigned int  numFrames,
Real  duration = 0 
)

Sets the names of the texture images for an animated texture.

Remarks
Animated textures are just a series of images making up the frames of the animation. All the images must be the same size, and their names must have a frame number appended before the extension, e.g. if you specify a name of "wall.jpg" with 3 frames, the image names must be "wall_0.jpg", "wall_1.jpg" and "wall_2.jpg".
You can change the active frame on a texture layer by calling the setCurrentFrame method.
Note
If you can't make your texture images conform to the naming standard laid out here, you can call the alternative setAnimatedTextureName method which takes an array of names instead.
Parameters
nameThe base name of the textures to use e.g. wall.jpg for frames wall_0.jpg, wall_1.jpg etc.
numFramesThe number of frames in the sequence.
durationThe length of time it takes to display the whole animation sequence, in seconds. If 0, no automatic transition occurs.

◆ setAnimatedTextureName() [2/2]

void Ogre::TextureUnitState::setAnimatedTextureName ( const String *const  names,
unsigned int  numFrames,
Real  duration = 0 
)

Sets the names of the texture images for an animated texture.

Remarks
This an alternative method to the one where you specify a single name and let the system derive the names of each frame, incase your images can't conform to this naming standard.
Animated textures are just a series of images making up the frames of the animation. All the images must be the same size, and you must provide their names as an array in the first parameter. You can change the active frame on a texture layer by calling the setCurrentFrame method.
Note
If you can make your texture images conform to a naming standard of basicName_frame.ext, you can call the alternative setAnimatedTextureName method which just takes a base name instead.
Parameters
namesPointer to array of names of the textures to use, in frame order.
numFramesThe number of frames in the sequence.
durationThe length of time it takes to display the whole animation sequence, in seconds. If 0, no automatic transition occurs.

◆ setAutomaticBatching()

void Ogre::TextureUnitState::setAutomaticBatching ( bool  automaticBatching)

When a texture is used by both PBS datablocks and V1 materials it can lead to a few issues:

  1. V1 materials will often expect a Type2D texture to actually be Type2D.
  2. PBS datablocks will use TextureFlags::AutomaticBatching to group several textures of same resolution and format into the same Type2DArray, and thus lower CPU overhead. This means the 2D texture is not actually Type2D, but rather Type2DArray, and the slice information is also required.
    The default is to disable this option, which means the texture may be loaded twice: one for V1 materials, and another for PBS. If you do not want this, call setAutomaticBatching( true ); before loading the texture. Note that you will have to provide the slice index by hand and make sure the shader you wrote understands this is a 2D Array texture.
    Parameters
    automaticBatching

◆ setBindingType()

void Ogre::TextureUnitState::setBindingType ( BindingType  bt)

Sets the type of unit these texture settings should be bound to.

Remarks
Some render systems, when implementing vertex texture fetch, separate the binding of textures for use in the vertex program versus those used in fragment programs. This setting allows you to target the vertex processing unit with a texture binding, in those cases. For rendersystems which have a unified binding for the vertex and fragment units, this setting makes no difference.

◆ setBlank()

void Ogre::TextureUnitState::setBlank ( )

Sets this texture layer to be blank.

◆ setColourOperation()

void Ogre::TextureUnitState::setColourOperation ( const LayerBlendOperation  op)

Determines how this texture layer is combined with the one below it (or the diffuse colour of the geometry if this is layer 0).

Remarks
This method is the simplest way to blend tetxure layers, because it requires only one parameter, gives you the most common blending types, and automatically sets up 2 blending methods: one for if single-pass multitexturing hardware is available, and another for if it is not and the blending must be achieved through multiple rendering passes. It is, however, quite limited and does not expose the more flexible multitexturing operations, simply because these can't be automatically supported in multipass fallback mode. If want to use the fancier options, use TextureUnitState::setColourOperationEx, but you'll either have to be sure that enough multitexturing units will be available, or you should explicitly set a fallback using TextureUnitState::setColourOpMultipassFallback.
Note
The default method is LBO_MODULATE for all layers.
This option has no effect in the programmable pipeline.
Parameters
opOne of the LayerBlendOperation enumerated blending types.

◆ setColourOperationEx()

void Ogre::TextureUnitState::setColourOperationEx ( LayerBlendOperationEx  op,
LayerBlendSource  source1 = LBS_TEXTURE,
LayerBlendSource  source2 = LBS_CURRENT,
const ColourValue arg1 = ColourValue::White,
const ColourValue arg2 = ColourValue::White,
Real  manualBlend = 0.0 
)

Setting advanced blending options.

Remarks
This is an extended version of the TextureUnitState::setColourOperation method which allows extremely detailed control over the blending applied between this and earlier layers. See the IMPORTANT note below about the issues between mulitpass and multitexturing that using this method can create.
Texture colour operations determine how the final colour of the surface appears when rendered. Texture units are used to combine colour values from various sources (ie. the diffuse colour of the surface from lighting calculations, combined with the colour of the texture). This method allows you to specify the 'operation' to be used, ie. the calculation such as adds or multiplies, and which values to use as arguments, such as a fixed value or a value from a previous calculation.
The defaults for each layer are:
  • op = LBX_MODULATE
  • source1 = LBS_TEXTURE
  • source2 = LBS_CURRENT
ie. each layer takes the colour results of the previous layer, and multiplies them with the new texture being applied. Bear in mind that colours are RGB values from 0.0 - 1.0 so multiplying them together will result in values in the same range, 'tinted' by the multiply. Note however that a straight multiply normally has the effect of darkening the textures - for this reason there are brightening operations like LBO_MODULATE_X2. See the LayerBlendOperation and LayerBlendSource enumerated types for full details.
Note
Because of the limitations on some underlying APIs (Direct3D included) the LBS_TEXTURE argument can only be used as the first argument, not the second.
The final 3 parameters are only required if you decide to pass values manually into the operation, i.e. you want one or more of the inputs to the colour calculation to come from a fixed value that you supply. Hence you only need to fill these in if you supply LBS_MANUAL to the corresponding source, or use the LBX_BLEND_MANUAL operation.
Warning
Ogre tries to use multitexturing hardware to blend texture layers together. However, if it runs out of texturing units (e.g. 2 of a GeForce2, 4 on a GeForce3) it has to fall back on multipass rendering, i.e. rendering the same object multiple times with different textures. This is both less efficient and there is a smaller range of blending operations which can be performed. For this reason, if you use this method you MUST also call TextureUnitState::setColourOpMultipassFallback to specify which effect you want to fall back on if sufficient hardware is not available.
Note
This has no effect in the programmable pipeline.
If you wish to avoid having to do this, use the simpler TextureUnitState::setColourOperation method which allows less flexible blending options but sets up the multipass fallback automatically, since it only allows operations which have direct multipass equivalents.
Parameters
opThe operation to be used, e.g. modulate (multiply), add, subtract.
source1The source of the first colour to the operation e.g. texture colour.
source2The source of the second colour to the operation e.g. current surface colour.
arg1Manually supplied colour value (only required if source1 = LBS_MANUAL).
arg2Manually supplied colour value (only required if source2 = LBS_MANUAL).
manualBlendManually supplied 'blend' value - only required for operations which require manual blend e.g. LBX_BLEND_MANUAL.

◆ setColourOpMultipassFallback()

void Ogre::TextureUnitState::setColourOpMultipassFallback ( const SceneBlendFactor  sourceFactor,
const SceneBlendFactor  destFactor 
)

Sets the multipass fallback operation for this layer, if you used TextureUnitState::setColourOperationEx and not enough multitexturing hardware is available.

Remarks
Because some effects exposed using TextureUnitState::setColourOperationEx are only supported under multitexturing hardware, if the hardware is lacking the system must fallback on multipass rendering, which unfortunately doesn't support as many effects. This method is for you to specify the fallback operation which most suits you.
You'll notice that the interface is the same as the Material::setSceneBlending method; this is because multipass rendering IS effectively scene blending, since each layer is rendered on top of the last using the same mechanism as making an object transparent, it's just being rendered in the same place repeatedly to get the multitexture effect.
If you use the simpler (and hence less flexible) TextureUnitState::setColourOperation method you don't need to call this as the system sets up the fallback for you.
Note
This option has no effect in the programmable pipeline, because there is no multipass fallback and multitexture blending is handled by the fragment shader.

◆ setCompositorReference()

void Ogre::TextureUnitState::setCompositorReference ( const String textureName)

Set the compositor reference for this texture unit state.

Remarks
Only valid when content type is compositor.
Parameters
textureNameThe name of the texture to reference.

◆ setContentType()

void Ogre::TextureUnitState::setContentType ( ContentType  ct)

Set the type of content this TextureUnitState references.

Remarks
The default is to reference a standard named texture, but this unit can also reference automated content like a shadow texture.

◆ setCubicTexture()

void Ogre::TextureUnitState::setCubicTexture ( TextureGpu *const *  texPtrs,
bool  forUVW = false 
)

Sets this texture layer to use a combination of 6 texture maps, each one relating to a face of a cube.

Remarks
Cubic textures are made up of 6 separate texture images. Each one of these is an orthogonal view of the world with a FOV of 90 degrees and an aspect ratio of 1:1. You can generate these from 3D Studio by rendering a scene to a reflection map of a transparent cube and saving the output files.
Cubic maps can be used either for skyboxes (complete wrap-around skies, like space) or as environment maps to simulate reflections. The system deals with these 2 scenarios in different ways:
  1. for cubic environment maps, the 6 textures are combined into a single 'cubic' texture map which is then addressed using 3D texture coordinates. This is required because you don't know what face of the box you're going to need to address when you render an object, and typically you need to reflect more than one face on the one object, so all 6 textures are needed to be 'active' at once. Cubic environment maps are enabled by calling this method with the forUVW parameter set to true, and then calling setEnvironmentMap(true).

    Note that not all cards support cubic environment mapping.

  2. for skyboxes, the 6 textures are kept separate and used independently for each face of the skybox. This is done because not all cards support 3D cubic maps and skyboxes do not need to use 3D texture coordinates so it is simpler to render each face of the box with 2D coordinates, changing texture between faces.

    Skyboxes are created by calling SceneManager::setSkyBox.

Parameters
texPtrsThe 6 pointers to the textures which make up the 6 sides of the box. The textures must all be the same size and be powers of 2 in width & height. Must be an Ogre::TextureGpu array with a length of 6 unless forUVW is set to true.
forUVWSet to true if you want a single 3D texture addressable with 3D texture coordinates rather than 6 separate textures. Useful for cubic environment mapping.

◆ setCubicTextureName() [1/2]

void Ogre::TextureUnitState::setCubicTextureName ( const String name,
bool  forUVW = false 
)

Sets this texture layer to use a combination of 6 texture maps, each one relating to a face of a cube.

Remarks
Cubic textures are made up of 6 separate texture images. Each one of these is an orthogonal view of the world with a FOV of 90 degrees and an aspect ratio of 1:1. You can generate these from 3D Studio by rendering a scene to a reflection map of a transparent cube and saving the output files.

    Skyboxes are created by calling SceneManager::setSkyBox.

Parameters
nameThe basic name of the texture e.g. brickwall.jpg, stonefloor.png. There must be 6 versions of this texture with the suffixes _fr, _bk, _up, _dn, _lf, and _rt (before the extension) which make up the 6 sides of the box. The textures must all be the same size and be powers of 2 in width & height. If you can't make your texture names conform to this, use the alternative method of the same name which takes an array of texture names instead.
forUVWSet to true if you want a single 3D texture addressable with 3D texture coordinates rather than 6 separate textures. Useful for cubic environment mapping.

◆ setCubicTextureName() [2/2]

void Ogre::TextureUnitState::setCubicTextureName ( const String *const  names,
bool  forUVW = false 
)

Sets this texture layer to use a combination of 6 texture maps, each one relating to a face of a cube.

Remarks
Cubic textures are made up of 6 separate texture images. Each one of these is an orthogonal view of the world with a FOV of 90 degrees and an aspect ratio of 1:1. You can generate these from 3D Studio by rendering a scene to a reflection map of a transparent cube and saving the output files.

Parameters
namesThe 6 names of the textures which make up the 6 sides of the box. The textures must all be the same size and be powers of 2 in width & height. Must be an Ogre::String array with a length of 6 unless forUVW is set to true.
forUVWSet to true if you want a single 3D texture addressable with 3D texture coordinates rather than 6 separate textures. Useful for cubic environment mapping.

◆ setCurrentFrame()

void Ogre::TextureUnitState::setCurrentFrame ( unsigned int  frameNumber)

Changes the active frame in an animated or multi-image texture.

Remarks
An animated texture (or a cubic texture where the images are not combined for 3D use) is made up of a number of frames. This method sets the active frame.

◆ setEnvironmentMap()

void Ogre::TextureUnitState::setEnvironmentMap ( bool  enable,
EnvMapType  envMapType = ENV_CURVED 
)

Turns on/off texture coordinate effect that makes this layer an environment map.

Remarks
Environment maps make an object look reflective by using the object's vertex normals relative to the camera view to generate texture coordinates.
The vectors generated can either be used to address a single 2D texture which is a 'fish-eye' lens view of a scene, or a 3D cubic environment map which requires 6 textures for each side of the inside of a cube. The type depends on what texture you set up - if you use the setTextureName method then a 2D fisheye lens texture is required, whereas if you used setCubicTextureName then a cubic environment map will be used.
This effect works best if the object has lots of gradually changing normals. The texture also has to be designed for this effect - see the example spheremap.png included with the sample application for a 2D environment map; a cubic map can be generated by rendering 6 views of a scene to each of the cube faces with orthogonal views.
Note
Enabling this disables any other texture coordinate generation effects. However it can be combined with texture coordinate modification functions, which then operate on the generated coordinates rather than static model texture coordinates.
Parameters
enableTrue to enable, false to disable
envMapTypeThe type of environment mapping to perform. Planar, curved, reflection or normal.

EnvMapType
Note
This option has no effect in the programmable pipeline.

◆ setFrameTextureName()

void Ogre::TextureUnitState::setFrameTextureName ( const String name,
unsigned int  frameNumber 
)

Sets the name of the texture associated with a frame.

Parameters
nameThe name of the texture.
frameNumberThe frame the texture name is to be placed in.
Note
Throws an exception if frameNumber exceeds the number of stored frames.

◆ setGamma()

void Ogre::TextureUnitState::setGamma ( Real  gamma)
inline

◆ setHardwareGammaEnabled()

void Ogre::TextureUnitState::setHardwareGammaEnabled ( bool  enabled)

◆ setIsAlpha()

void Ogre::TextureUnitState::setIsAlpha ( bool  isAlpha)

Sets whether this texture is requested to be loaded as alpha if single channel.

◆ setName()

void Ogre::TextureUnitState::setName ( const String name)

Set the name of the Texture Unit State.

Remarks
The name of the Texture Unit State is optional. Its useful in material scripts where a material could inherit from another material and only want to modify a particalar Texture Unit State.

◆ setNumMipmaps()

void Ogre::TextureUnitState::setNumMipmaps ( int  numMipmaps)

Sets how many mipmaps have been requested for the texture.

◆ setProjectiveTexturing()

void Ogre::TextureUnitState::setProjectiveTexturing ( bool  enabled,
const Frustum projectionSettings = 0 
)

Enables or disables projective texturing on this texture unit.

Remarks
Projective texturing allows you to generate texture coordinates based on a Frustum, which gives the impression that a texture is being projected onto the surface. Note that once you have called this method, the texture unit continues to monitor the Frustum you passed in and the projection will change if you can alter it. It also means that you must ensure that the Frustum object you pass a pointer to remains in existence for as long as this TextureUnitState does.
This effect cannot be combined with other texture generation effects, such as environment mapping. It also has no effect on passes which have a vertex program enabled - projective texturing has to be done in the vertex program instead.
Parameters
enabledWhether to enable / disable.
projectionSettingsThe Frustum which will be used to derive the projection parameters.

◆ setRotateAnimation()

void Ogre::TextureUnitState::setRotateAnimation ( Real  speed)

Sets up an animated texture rotation for this layer.

Note
Useful for constant rotations (for varying rotations, see setTransformAnimation).
Parameters
speedThe number of complete anticlockwise revolutions per second (use -ve for clockwise)
Note
This option has no effect in the programmable pipeline.

◆ setSamplerblock()

void Ogre::TextureUnitState::setSamplerblock ( const HlmsSamplerblock samplerblock)

Changes the current samplerblock for a new one.

◆ setScrollAnimation()

void Ogre::TextureUnitState::setScrollAnimation ( Real  uSpeed,
Real  vSpeed 
)

Sets up an animated scroll for the texture layer.

Note
Useful for creating constant scrolling effects on a texture layer (for varying scrolls, see setTransformAnimation).
Parameters
uSpeedThe number of horizontal loops per second (+ve=moving right, -ve = moving left).
vSpeedThe number of vertical loops per second (+ve=moving up, -ve= moving down).
Note
This option has no effect in the programmable pipeline.

◆ setTexture()

void Ogre::TextureUnitState::setTexture ( TextureGpu texPtr)

Sets this texture layer to use a single texture, given the pointer to the texture to use on this layer.

◆ setTextureName()

void Ogre::TextureUnitState::setTextureName ( const String name,
TextureTypes::TextureTypes  ttype = TextureTypes::Type2D 
)

Sets this texture layer to use a single texture, given the name of the texture to use on this layer.

◆ setTextureNameAlias()

void Ogre::TextureUnitState::setTextureNameAlias ( const String name)

Set the alias name used for texture frame names.

Parameters
nameCan be any sequence of characters and does not have to be unique.

◆ setTextureRotate()

void Ogre::TextureUnitState::setTextureRotate ( const Radian angle)

Sets the anticlockwise rotation factor applied to texture coordinates.

Remarks
This sets a fixed rotation angle - if you wish to animate this, see the ControllerManager::createTextureRotater method.
Note
Has no effect in the programmable pipeline.
Parameters
angleThe angle of rotation (anticlockwise).

◆ setTextureScale()

void Ogre::TextureUnitState::setTextureScale ( Real  uScale,
Real  vScale 
)

Sets the scaling factor applied to texture coordinates.

Remarks
This method sets the scale element of the texture transformation, and is easier to use than setTextureTransform if you are combining translation, scaling and rotation in your texture transformation. Again if you want to animate these values you need to use a Controller (see ControllerManager and it's methods for more information).
Note
Has no effect in the programmable pipeline.
Parameters
uScaleThe value by which the texture is to be scaled horizontally.
vScaleThe value by which the texture is to be scaled vertically.

◆ setTextureScroll()

void Ogre::TextureUnitState::setTextureScroll ( Real  u,
Real  v 
)

Sets the translation offset of the texture, ie scrolls the texture.

Remarks
This method sets the translation element of the texture transformation, and is easier to use than setTextureTransform if you are combining translation, scaling and rotation in your texture transformation. Again if you want to animate these values you need to use a Controller
Note
Has no effect in the programmable pipeline.
Parameters
uThe amount the texture should be moved horizontally (u direction).
vThe amount the texture should be moved vertically (v direction).
See also
ControllerManager, Controller

◆ setTextureTransform()

void Ogre::TextureUnitState::setTextureTransform ( const Matrix4 xform)

Sets a matrix used to transform any texture coordinates on this layer.

Remarks
Texture coordinates can be modified on a texture layer to create effects like scrolling textures. A texture transform can either be applied to a layer which takes the source coordinates from a fixed set in the geometry, or to one which generates them dynamically (e.g. environment mapping).
It's obviously a bit impractical to create scrolling effects by calling this method manually since you would have to call it every framw with a slight alteration each time, which is tedious. Instead you can use the ControllerManager class to create a Controller object which will manage the effect over time for you. See the ControllerManager::createTextureScroller and it's sibling methods for details.
In addition, if you want to set the individual texture transformations rather than concatenating them yourself, use setTextureScroll, setTextureScale and setTextureRotate.
Note
Has no effect in the programmable pipeline.

◆ setTextureUScale()

void Ogre::TextureUnitState::setTextureUScale ( Real  value)

As setTextureScale, but sets only U value.

Note
Has no effect in the programmable pipeline.

◆ setTextureUScroll()

void Ogre::TextureUnitState::setTextureUScroll ( Real  value)

As setTextureScroll, but sets only U value.

Note
Has no effect in the programmable pipeline.

◆ setTextureVScale()

void Ogre::TextureUnitState::setTextureVScale ( Real  value)

As setTextureScale, but sets only V value.

Note
Has no effect in the programmable pipeline.

◆ setTextureVScroll()

void Ogre::TextureUnitState::setTextureVScroll ( Real  value)

As setTextureScroll, but sets only V value.

Note
Has no effect in the programmable pipeline.

◆ setTransformAnimation()

void Ogre::TextureUnitState::setTransformAnimation ( const TextureTransformType  ttype,
const WaveformType  waveType,
Real  base = 0,
Real  frequency = 1,
Real  phase = 0,
Real  amplitude = 1 
)

Sets up a general time-relative texture modification effect.

Note
This can be called multiple times for different values of ttype, but only the latest effect applies if called multiple time for the same ttype.
Parameters
ttypeThe type of transform, either translate (scroll), scale (stretch) or rotate (spin).
waveTypeThe shape of the wave, see WaveformType enum for details.
baseThe base value for the function (range of output = {base, base + amplitude}).
frequencyThe speed of the wave in cycles per second.
phaseThe offset of the start of the wave, e.g. 0.5 to start half-way through the wave.
amplitudeScales the output so that instead of lying within 0..1 it lies within 0..1*amplitude for exaggerated effects.
Note
This option has no effect in the programmable pipeline.
