Detailed Description

Class defining a single pass of a Technique (of a Material), i.e.

a single rendering call.

Remarks: Rendering can be repeated with many passes for more complex effects. Each pass is either a fixed-function pass (meaning it does not use a vertex or fragment program) or a programmable pass (meaning it does use either a vertex and fragment program, or both).

: Programmable passes are complex to define, because they require custom programs and you have to set all constant inputs to the programs (like the position of lights, any base material colours you wish to use etc), but they do give you much total flexibility over the algorithms used to render your pass, and you can create some effects which are impossible with a fixed-function pass. On the other hand, you can define a fixed-function pass in very little time, and you can use a range of fixed-function effects like environment mapping very easily, plus your pass will be more likely to be compatible with older hardware. There are pros and cons to both, just remember that if you use a programmable pass to create some great effects, allow more time for definition and testing.

Sets the ambient colour reflectance properties of this pass.

Remarks: The base colour of a pass is determined by how much red, green and blue light is reflects (provided texture layer #0 has a blend mode other than LBO_REPLACE). This property determines how much ambient light (directionless global light) is reflected. The default is full white, meaning objects are completely globally illuminated. Reduce this if you want to see diffuse or specular light effects, or change the blend of colours to make the object have a base colour other than white.

Note: This setting has no effect if dynamic lighting is disabled (see Pass::setLightingEnabled), or if this is a programmable pass.

◆ setAmbient() [2/2]

void Ogre::Pass::setAmbient	(	Real	red,
		Real	green,
		Real	blue
	)

Sets the ambient colour reflectance properties of this pass.

Remarks: The base colour of a pass is determined by how much red, green and blue light is reflects (provided texture layer #0 has a blend mode other than LBO_REPLACE). This property determines how much ambient light (directionless global light) is reflected. The default is full white, meaning objects are completely globally illuminated. Reduce this if you want to see diffuse or specular light effects, or change the blend of colours to make the object have a base colour other than white.

Note: This setting has no effect if dynamic lighting is disabled (see Pass::setLightingEnabled), or if this is a programmable pass.

◆ setBlendblock()

		bool	resetParams = `true`
	)

Sets the details of the compute program to use.

Remarks: Only applicable to programmable passes, this sets the details of the compute program to use in this pass. The program will not be loaded until the parent Material is loaded.

Parameters

name	The name of the program - this must have been created using GpuProgramManager by the time that this Pass is loaded. If this parameter is blank, any compute program in this pass is disabled.
resetParams	If true, this will create a fresh set of parameters from the new program being linked, so if you had previously set parameters you will have to set them again. If you set this to false, you must be absolutely sure that the parameters match perfectly, and in the case of named parameters refers to the indexes underlying them, not just the names.

◆ setComputeProgramParameters()

void Ogre::Pass::setComputeProgramParameters ( GpuProgramParametersSharedPtr params )

Sets the Tessellation Evaluation program parameters.

Remarks: Only applicable to programmable passes.

◆ setDiffuse() [1/2]

void Ogre::Pass::setDiffuse ( const ColourValue & diffuse )

Sets the diffuse colour reflectance properties of this pass.

Remarks: The base colour of a pass is determined by how much red, green and blue light is reflects (provided texture layer #0 has a blend mode other than LBO_REPLACE). This property determines how much diffuse light (light from instances of the Light class in the scene) is reflected. The default is full white, meaning objects reflect the maximum white light they can from Light objects.

Note: This setting has no effect if dynamic lighting is disabled (see Pass::setLightingEnabled), or if this is a programmable pass.

◆ setDiffuse() [2/2]

void Ogre::Pass::setDiffuse	(	Real	red,
		Real	green,
		Real	blue,
		Real	alpha
	)

Remarks: The base colour of a pass is determined by how much red, green and blue light is reflects (provided texture layer #0 has a blend mode other than LBO_REPLACE). This property determines how much diffuse light (light from instances of the Light class in the scene) is reflected. The default is full white, meaning objects reflect the maximum white light they can from Light objects.

Note: This setting has no effect if dynamic lighting is disabled (see Pass::setLightingEnabled), or if this is a programmable pass.

◆ setFog()

void Ogre::Pass::setFog	(	bool	overrideScene,
		FogMode	mode = `FOG_NONE`,
		const ColourValue &	colour = `ColourValue::White`,
		Real	expDensity = `0.001`,
		Real	linearStart = `0.0`,
		Real	linearEnd = `1.0`
	)

Sets the fogging mode applied to this pass.

Remarks: Fogging is an effect that is applied as polys are rendered. Sometimes, you want fog to be applied to an entire scene. Other times, you want it to be applied to a few polygons only. This pass-level specification of fog parameters lets you easily manage both.

: The SceneManager class also has a setFog method which applies scene-level fog. This method lets you change the fog behaviour for this pass compared to the standard scene-level fog.

Parameters

overrideScene	If true, you authorise this pass to override the scene's fog params with it's own settings. If you specify false, so other parameters are necessary, and this is the default behaviour for passes.
mode	Only applicable if overrideScene is true. You can disable fog which is turned on for the rest of the scene by specifying FOG_NONE. Otherwise, set a pass-specific fog mode as defined in the enum FogMode.
colour	The colour of the fog. Either set this to the same as your viewport background colour, or to blend in with a skydome or skybox.
expDensity	The density of the fog in FOG_EXP or FOG_EXP2 mode, as a value between 0 and 1. The default is 0.001.
linearStart	Distance in world units at which linear fog starts to encroach. Only applicable if mode is FOG_LINEAR.
linearEnd	Distance in world units at which linear fog becomes completely opaque. Only applicable if mode is FOG_LINEAR.

◆ setFragmentProgram()

void Ogre::Pass::setFragmentProgram	(	const String &	name,
		bool	resetParams = `true`
	)

Sets the details of the fragment program to use.

Remarks: Only applicable to programmable passes, this sets the details of the fragment program to use in this pass. The program will not be loaded until the parent Material is loaded.

Parameters

name	The name of the program - this must have been created using GpuProgramManager by the time that this Pass is loaded. If this parameter is blank, any fragment program in this pass is disabled.
resetParams	If true, this will create a fresh set of parameters from the new program being linked, so if you had previously set parameters you will have to set them again. If you set this to false, you must be absolutely sure that the parameters match perfectly, and in the case of named parameters refers to the indexes underlying them, not just the names.

◆ setFragmentProgramParameters()

void Ogre::Pass::setFragmentProgramParameters ( GpuProgramParametersSharedPtr params )

Sets the fragment program parameters.

Remarks: Only applicable to programmable passes.

◆ setGeometryProgram()

void Ogre::Pass::setGeometryProgram	(	const String &	name,
		bool	resetParams = `true`
	)

Sets the details of the geometry program to use.

Remarks: Only applicable to programmable passes, this sets the details of the geometry program to use in this pass. The program will not be loaded until the parent Material is loaded.

Parameters

name	The name of the program - this must have been created using GpuProgramManager by the time that this Pass is loaded. If this parameter is blank, any geometry program in this pass is disabled.
resetParams	If true, this will create a fresh set of parameters from the new program being linked, so if you had previously set parameters you will have to set them again. If you set this to false, you must be absolutely sure that the parameters match perfectly, and in the case of named parameters refers to the indexes underlying them, not just the names.

◆ setGeometryProgramParameters()

void Ogre::Pass::setGeometryProgramParameters ( GpuProgramParametersSharedPtr params )

Sets the geometry program parameters.

Remarks: Only applicable to programmable passes.

◆ setIteratePerLight()

void Ogre::Pass::setIteratePerLight	(	bool	enabled,
		bool	onlyForOneLightType = `true`,
		Light::LightTypes	lightType = `Light::LT_POINT`
	)

Sets whether or not this pass should iterate per light or number of lights which can affect the object being rendered.

Remarks: The default behaviour for a pass (when this option is 'false'), is for a pass to be rendered only once (or the number of times set in setPassIterationCount), with all the lights which could affect this object set at the same time (up to the maximum lights allowed in the render system, which is typically 8).

Setting this option to 'true' changes this behaviour, such that instead of trying to issue render this pass once per object, it is run per light, or for a group of 'n' lights each time which can affect this object, the number of times set in setPassIterationCount (default is once). In this case, only light index 0 is ever used, and is a different light every time the pass is issued, up to the total number of lights which is affecting this object. This has 2 advantages:

There is no limit on the number of lights which can be supported
It's easier to write vertex / fragment programs for this because a single program can be used for any number of lights

However, this technique is more expensive, and typically you will want an additional ambient pass, because if no lights are affecting the object it will not be rendered at all, which will look odd even if ambient light is zero (imagine if there are lit objects behind it - the objects silhouette would not show up). Therefore, use this option with care, and you would be well advised to provide a less expensive fallback technique for use in the distance.

Note: The number of times this pass runs is still limited by the maximum number of lights allowed as set in setMaxSimultaneousLights, so you will never get more passes than this. Also, the iteration is started from the 'start light' as set in Pass::setStartLight, and the number of passes is the number of lights to iterate over divided by the number of lights per iteration (default 1, set by setLightCountPerIteration).

Parameters

enabled	Whether this feature is enabled
onlyForOneLightType	If true, the pass will only be run for a single type of light, other light types will be ignored.
lightType	The single light type which will be considered for this pass

◆ setLightClipPlanesEnabled()

void Ogre::Pass::setLightClipPlanesEnabled ( bool enabled )

inline

Gets whether or not this pass will be clipped by user clips planes bounding the area covered by the light.

Remarks: In order to cut down on the geometry set up to render this pass when you have a single fixed-range light being rendered through it, you can enable this option to request that during triangle setup, clip planes are defined to bound the range of the light. In the case of a point light these planes form a cube, and in the case of a spotlight they form a pyramid. Directional lights are never clipped.

: This option is only likely to be useful for multipass additive lighting algorithms, where the scene has already been 'seeded' with an ambient pass and this pass is just adding light in affected areas. In addition, it will only be honoured if there is exactly one non-directional light being used in this pass. Also, these clip planes override any user clip planes set on Camera.

Note: When using SHADOWTYPE_STENCIL_ADDITIVE or SHADOWTYPE_TEXTURE_ADDITIVE, this option is automatically used for all per-light passes if you enable SceneManager::setShadowUseLightClipPlanes and does not need to be specified. It is disabled by default since clip planes have a cost of their own which may not always exceed the benefits they give you.

◆ setLightCountPerIteration()

void Ogre::Pass::setLightCountPerIteration ( unsigned short c )

If light iteration is enabled, determine the number of lights per iteration.

Remarks: The default for this setting is 1, so if you enable light iteration (Pass::setIteratePerLight), the pass is rendered once per light. If you set this value higher, the passes will occur once per 'n' lights. The start of the iteration is set by Pass::setStartLight and the end by Pass::setMaxSimultaneousLights.

◆ setLightMask()

void Ogre::Pass::setLightMask ( uint32 mask )

Sets the light mask which can be matched to specific light flags to be handled by this pass.

◆ setLightScissoringEnabled()

void Ogre::Pass::setLightScissoringEnabled ( bool enabled )

inline

Sets whether or not this pass will be clipped by a scissor rectangle encompassing the lights that are being used in it.

Remarks: In order to cut down on fillrate when you have a number of fixed-range lights in the scene, you can enable this option to request that during rendering, only the region of the screen which is covered by the lights is rendered. This region is the screen-space rectangle covering the union of the spheres making up the light ranges. Directional lights are ignored for this.

: This is only likely to be useful for multipass additive lighting algorithms, where the scene has already been 'seeded' with an ambient pass and this pass is just adding light in affected areas.

Note: When using SHADOWTYPE_STENCIL_ADDITIVE or SHADOWTYPE_TEXTURE_ADDITIVE, this option is implicitly used for all per-light passes and does not need to be specified. If you are not using shadows or are using a modulative or an integrated shadow technique then this could be useful.

◆ setMacroblock()

void Ogre::Pass::setMacroblock ( const HlmsMacroblock & macroblock )

Changes the current macroblock for a new one. Pointer can't be null.

◆ setMaxSimultaneousLights()

void Ogre::Pass::setMaxSimultaneousLights ( unsigned short maxLights )

Sets the maximum number of lights to be used by this pass.

Remarks: During rendering, if lighting is enabled (or if the pass uses an automatic program parameter based on a light) the engine will request the nearest lights to the object being rendered in order to work out which ones to use. This parameter sets the limit on the number of lights which should apply to objects rendered with this pass.

◆ setName()

void Ogre::Pass::setName ( const String & name )

◆ setPassIterationCount()

void Ogre::Pass::setPassIterationCount ( const size_t count )

inline

set the number of iterations that this pass should perform when doing fast multi pass operation.

Remarks: Only applicable for programmable passes.

Parameters

count number of iterations to perform fast multi pass operations. A value greater than 1 will cause the pass to be executed count number of times without changing the render state. This is very useful for passes that use programmable shaders that have to iterate more than once but don't need a render state change. Using multi pass can dramatically speed up rendering for materials that do things like fur, blur. A value of 1 turns off multi pass operation and the pass does the normal pass operation.

◆ setPointAttenuation()

void Ogre::Pass::setPointAttenuation	(	bool	enabled,
		Real	constant = `0.0f`,
		Real	linear = `1.0f`,
		Real	quadratic = `0.0f`
	)

Sets how points are attenuated with distance.

Remarks: When performing point rendering or point sprite rendering, point size can be attenuated with distance. The equation for doing this is attenuation = 1 / (constant + linear * dist + quadratic * d^2).

: For example, to disable distance attenuation (constant screensize) you would set constant to 1, and linear and quadratic to 0. A standard perspective attenuation would be 0, 1, 0 respectively.

Note: The resulting size is clamped to the minimum and maximum point size.

Parameters

enabled	Whether point attenuation is enabled
constant,linear,quadratic	Parameters to the attenuation function defined above

◆ setPointMaxSize()

void Ogre::Pass::setPointMaxSize ( Real max )

Set the maximum point size, when point attenuation is in use.

Remarks: Setting this to 0 indicates the max size supported by the card.

◆ setPointMinSize()

void Ogre::Pass::setPointMinSize ( Real min )

Set the minimum point size, when point attenuation is in use.

◆ setPointSize()

void Ogre::Pass::setPointSize ( Real ps )

Sets the point size of this pass.

Remarks: This setting allows you to change the size of points when rendering a point list, or a list of point sprites. The interpretation of this command depends on the Pass::setPointSizeAttenuation option - if it is off (the default), the point size is in screen pixels, if it is on, it expressed as normalised screen coordinates (1.0 is the height of the screen) when the point is at the origin.

Note

Some drivers have an upper limit on the size of points they support

this can even vary between APIs on the same card! Don't rely on point sizes that cause the point sprites to get very large on screen, since they may get clamped on some cards. Upper sizes can range from 64 to 256 pixels.

◆ setPointSpritesEnabled()

void Ogre::Pass::setPointSpritesEnabled ( bool enabled )

Sets whether or not rendering points using OT_POINT_LIST will render point sprites (textured quads) or plain points (dots).

Parameters

enabled True enables point sprites, false returns to normal point rendering.

◆ setPolygonModeOverrideable()

virtual void Ogre::Pass::setPolygonModeOverrideable ( bool override )

inlinevirtual

Sets whether this pass's chosen detail level can be overridden (downgraded) by the camera setting.

Parameters

override true means that a lower camera detail will override this pass's detail level, false means it won't (default true).

◆ setSamplerblock()

void Ogre::Pass::setSamplerblock ( const HlmsSamplerblock & samplerblock )

Set samplerblock for every texture unit.

Note: This property actually exists on the TextureUnitState class For simplicity, this method allows you to set these properties for every current TeextureUnitState, If you need more precision, retrieve the TextureUnitState instance and set the property there.

See also: TextureUnitState::setSamplerblock

◆ setSelfIllumination() [1/2]

void Ogre::Pass::setSelfIllumination ( const ColourValue & selfIllum )

Sets the amount of self-illumination an object has.

Remarks: If an object is self-illuminating, it does not need external sources to light it, ambient or otherwise. It's like the object has it's own personal ambient light. This property is rarely useful since you can already specify per-pass ambient light, but is here for completeness.

Note: This setting has no effect if dynamic lighting is disabled (see Pass::setLightingEnabled), or if this is a programmable pass.

◆ setSelfIllumination() [2/2]

void Ogre::Pass::setSelfIllumination	(	Real	red,
		Real	green,
		Real	blue
	)

Sets the amount of self-illumination an object has.

Remarks: If an object is self-illuminating, it does not need external sources to light it, ambient or otherwise. It's like the object has it's own personal ambient light. This property is rarely useful since you can already specify per-pass ambient light, but is here for completeness.

Note: This setting has no effect if dynamic lighting is disabled (see Pass::setLightingEnabled), or if this is a programmable pass.

◆ setShadingMode()

void Ogre::Pass::setShadingMode ( ShadeOptions mode )

Sets the type of light shading required.

Note: The default shading method is Gouraud shading.

◆ setShadowCasterFragmentProgram()

void Ogre::Pass::setShadowCasterFragmentProgram ( const String & name )

Sets the details of the fragment program to use when rendering as a shadow caster.

Remarks: Texture-based shadows require that the caster is rendered to a texture in a solid colour (the shadow colour in the case of modulative texture shadows). Whilst Ogre can arrange this for the fixed function pipeline, passes which use vertex programs might need the vertex programs still to run in order to preserve any deformation etc that it does. However, lighting calculations must be a lot simpler, with only the ambient colour being used (which the engine will ensure is bound to the shadow colour).

: Therefore, it is up to implementors of vertex programs to provide an alternative vertex program which can be used to render the object to a shadow texture. Do all the same vertex transforms, but set the colour of the vertex to the ambient colour, as bound using the standard auto parameter binding mechanism.

Note: Some vertex programs will work without doing this, because Ogre ensures that all lights except for ambient are set black. However, the chances are that your vertex program is doing a lot of unnecessary work in this case, since the other lights are having no effect, and it is good practice to supply an alternative.; This is only applicable to programmable passes.

: The default behaviour is for Ogre to switch to fixed-function rendering if an explicit fragment program alternative is not set.

◆ setShadowCasterFragmentProgramParameters()

void Ogre::Pass::setShadowCasterFragmentProgramParameters ( GpuProgramParametersSharedPtr params )

Sets the fragment program parameters for rendering as a shadow caster.

Remarks: Only applicable to programmable passes, and this particular call is designed for low-level programs; use the named parameter methods for setting high-level program parameters.

◆ setShadowCasterVertexProgram()

void Ogre::Pass::setShadowCasterVertexProgram ( const String & name )

Sets the details of the vertex program to use when rendering as a shadow caster.

Remarks: Texture-based shadows require that the caster is rendered to a texture in a solid colour (the shadow colour in the case of modulative texture shadows). Whilst Ogre can arrange this for the fixed function pipeline, passes which use vertex programs might need the vertex programs still to run in order to preserve any deformation etc that it does.

◆ setShadowCasterVertexProgramParameters()

void Ogre::Pass::setShadowCasterVertexProgramParameters ( GpuProgramParametersSharedPtr params )

Sets the vertex program parameters for rendering as a shadow caster.

Remarks: Only applicable to programmable passes, and this particular call is designed for low-level programs; use the named parameter methods for setting high-level program parameters.

◆ setShininess()

void Ogre::Pass::setShininess ( Real val )

Sets the shininess of the pass, affecting the size of specular highlights.

Note: This setting has no effect if dynamic lighting is disabled (see Pass::setLightingEnabled), or if this is a programmable pass.

◆ setSpecular() [1/2]

void Ogre::Pass::setSpecular ( const ColourValue & specular )

Sets the specular colour reflectance properties of this pass.

Remarks: The base colour of a pass is determined by how much red, green and blue light is reflects (provided texture layer #0 has a blend mode other than LBO_REPLACE). This property determines how much specular light (highlights from instances of the Light class in the scene) is reflected. The default is to reflect no specular light.

Note: The size of the specular highlights is determined by the separate 'shininess' property.; This setting has no effect if dynamic lighting is disabled (see Pass::setLightingEnabled), or if this is a programmable pass.

◆ setSpecular() [2/2]

void Ogre::Pass::setSpecular	(	Real	red,
		Real	green,
		Real	blue,
		Real	alpha
	)

Sets the specular colour reflectance properties of this pass.

Remarks: The base colour of a pass is determined by how much red, green and blue light is reflects (provided texture layer #0 has a blend mode other than LBO_REPLACE). This property determines how much specular light (highlights from instances of the Light class in the scene) is reflected. The default is to reflect no specular light.

Note: The size of the specular highlights is determined by the separate 'shininess' property.; This setting has no effect if dynamic lighting is disabled (see Pass::setLightingEnabled), or if this is a programmable pass.

◆ setStartLight()

void Ogre::Pass::setStartLight ( unsigned short startLight )

Sets the light index that this pass will start at in the light list.

Remarks: Normally the lights passed to a pass will start from the beginning of the light list for this object. This option allows you to make this pass start from a higher light index, for example if one of your earlier passes could deal with lights 0-3, and this pass dealt with lights 4+. This option also has an interaction with pass iteration, in that if you choose to iterate this pass per light too, the iteration will only begin from light 4.

◆ setTessellationDomainProgram()

void Ogre::Pass::setTessellationDomainProgram	(	const String &	name,
		bool	resetParams = `true`
	)

Sets the details of the Tessellation domain program to use.

Remarks: Only applicable to programmable passes, this sets the details of the Tessellation domain program to use in this pass. The program will not be loaded until the parent Material is loaded.

Parameters

name	The name of the program - this must have been created using GpuProgramManager by the time that this Pass is loaded. If this parameter is blank, any Tessellation domain program in this pass is disabled.
resetParams	If true, this will create a fresh set of parameters from the new program being linked, so if you had previously set parameters you will have to set them again. If you set this to false, you must be absolutely sure that the parameters match perfectly, and in the case of named parameters refers to the indexes underlying them, not just the names.

◆ setTessellationDomainProgramParameters()

void Ogre::Pass::setTessellationDomainProgramParameters ( GpuProgramParametersSharedPtr params )

Sets the Tessellation Domain program parameters.

Remarks: Only applicable to programmable passes.

◆ setTessellationHullProgram()

Remarks: Only applicable to programmable passes, this sets the details of the Tessellation Hull program to use in this pass. The program will not be loaded until the parent Material is loaded.

Parameters

name	The name of the program - this must have been created using GpuProgramManager by the time that this Pass is loaded. If this parameter is blank, any Tessellation Hull program in this pass is disabled.
resetParams	If true, this will create a fresh set of parameters from the new program being linked, so if you had previously set parameters you will have to set them again. If you set this to false, you must be absolutely sure that the parameters match perfectly, and in the case of named parameters refers to the indexes underlying them, not just the names.
