Constructor & Destructor Documentation

◆ HlmsUnlitMobileDatablock()

Ogre::HlmsUnlitMobileDatablock::HlmsUnlitMobileDatablock ( IdString  name,
Hlms creator,
const HlmsMacroblock macroblock,
const HlmsBlendblock blendblock,
const HlmsParamVec params 
)

Valid parameters in params:

Parameters
paramsdiffuse [r g b [a]] If absent, the values of mR, mG, mB & mA will be ignored by the pixel shader. When present, the rgba values can be specified. Default: Absent Default (when present): diffuse 1 1 1 1

diffuse_map [texture name] [#uv] Name of the diffuse texture for the base image (optional, otherwise a dummy is set) The #uv parameter is optional, and specifies the texcoord set that will be used. Valid range is [0; 8) If the Renderable doesn't have enough UV texcoords, HLMS will throw an exception.

Note: The UV set is evaluated when creating the Renderable cache.

diffuse_map1 [texture name] [blendmode] [#uv] Name of the diffuse texture that will be layered on top of the base image. The #uv parameter is optional. Valid range is [0; 8) The blendmode parameter is optional. Valid values are: NormalNonPremul, NormalPremul, Add, Subtract, Multiply, Multiply2x, Screen, Overlay, Lighten, Darken, GrainExtract, GrainMerge, Difference which are very similar to Photoshop/GIMP's blend modes. See Samples/Media/Hlms/GuiMobile/GLSL/BlendModes_piece_ps.glsl for the exact math. Default blendmode: NormalPremul Default uv: 0 Example: diffuse_map1 myTexture.png Add 3

diffuse_map2 through diffuse_map16 Same as diffuse_map1 but for subsequent layers to be applied on top of the previous images. You can't leave gaps (i.e. specify diffuse_map0 & diffuse_map2 but not diffuse_map1). Note that not all mobile HW supports 16 textures at the same time, thus we will just cut/ignore the extra textures that won't fit (we log a warning though).

animate <#uv> [<#uv> <#uv> ... <#uv>] Enables texture animation through a 4x4 matrix for the specified UV sets. Default: All UV set animation/manipulation disabled. Example: animate 0 1 2 3 4 5 6 7

alpha_test [compare_func] [threshold] When present, mAlphaTestThreshold is used. compare_func is optional. Valid values are: less, less_equal, equal, greater, greater_equal, not_equal Threshold is optional, and a value in the range (0; 1) Default: alpha_test less 0.5 Example: alpha_test equal 0.1

◆ saveTextures()

virtual void Ogre::HlmsDatablock::saveTextures ( const String folderPath,
set< String >::type &  savedTextures,
bool  saveOitd,
bool  saveOriginal,
HlmsTextureExportListener listener 
)
virtualinherited
Remarks
It's possible to set both saveOitd & saveOriginal to true, but will likely double storage requirements (2x as many textures). Setting both to true is useful for troubleshooting obscure Ogre bugs.
Parameters
folderPathFolder where to dump the textures.
savedTextures[in/out] Set of texture names. Textures whose name is already in the set won't be saved again. Textures that were saved will be inserted into the set.
saveOitdWhen true, we will download the texture from GPU and save it in OITD format. OITD is faster to load as it's stored in Ogre's native format it understands, but it cannot be opened by traditional image editors; also OITD is not backwards compatible with older versions of Ogre.
saveOriginalWhen true, we will attempt to read the raw filestream of the original texture and save it (i.e. copy the original png/dds/etc file).

Reimplemented in Ogre::HlmsPbsDatablock.

◆ setAlphaTest()

virtual void Ogre::HlmsDatablock::setAlphaTest ( CompareFunction  compareFunction,
bool  shadowCasterOnly = false 
)
virtualinherited

Sets the alpha test to the given compare function.

CMPF_ALWAYS_PASS means disabled.

See also
mAlphaTestThreshold. Calling this function triggers a HlmsDatablock::flushRenderables
Remarks
It is to the derived implementation to actually implement the alpha test.
Parameters
compareFunctionCompare function to use. Default is CMPF_ALWAYS_PASS, which means disabled. Note: CMPF_ALWAYS_FAIL is not supported. Set a negative threshold to workaround this issue.

◆ setAlphaTestThreshold()

virtual void Ogre::HlmsDatablock::setAlphaTestThreshold ( float  threshold)
virtualinherited

Alpha test's threshold.

See also
setAlphaTest
Parameters
thresholdValue typically in the range [0; 1)

Reimplemented in Ogre::HlmsPbsDatablock, and Ogre::HlmsPbsMobileDatablock.

◆ setBlendblock() [1/2]

void Ogre::HlmsDatablock::setBlendblock ( const HlmsBlendblock blendblock,
bool  casterBlock = false 
)
inherited

Sets a new blendblock that matches the same parameter as the input.

Decreases the reference count of the previous mBlendblock. Runs an O(N) search to get the right block. Calling this function triggers a HlmsDatablock::flushRenderables

Parameters
blendblock@See HlmsManager::getBlendblock
casterBlockTrue to directly set the blendblock to be used during the shadow mapping's caster pass. Note that when false, it will reset the caster block to the same as the regular one.

◆ setBlendblock() [2/2]

void Ogre::HlmsDatablock::setBlendblock ( const HlmsBlendblock blendblock,
bool  casterBlock = false 
)
inherited

Sets the blendblock from the given pointer that was already retrieved from the HlmsManager.

Unlike the other overload, this operation is O(1). Calling this function triggers a HlmsDatablock::flushRenderables

Parameters
blendblockA valid block. The reference count is increased inside this function.
casterBlockTrue to directly set the blendblock to be used during the shadow mapping's caster pass. Note that when false, it will reset the caster block to the same as the regular one.

◆ setColour()

void Ogre::HlmsUnlitMobileDatablock::setColour ( const ColourValue diffuse)

Sets a new colour value. Asserts if mHasColour is false.

◆ setMacroblock() [1/2]

void Ogre::HlmsDatablock::setMacroblock ( const HlmsMacroblock macroblock,
bool  casterBlock = false 
)
inherited

Sets a new macroblock that matches the same parameter as the input.

Decreases the reference count of the previously set one. Runs an O(N) search to get the right block. Calling this function triggers a HlmsDatablock::flushRenderables

Parameters
macroblock@See HlmsManager::getMacroblock
casterBlockTrue to directly set the macroblock to be used during the shadow mapping's caster pass. Note that when false, it will automatically reset the caster's block according to HlmsManager::setShadowMappingUseBackFaces setting.

◆ setMacroblock() [2/2]

void Ogre::HlmsDatablock::setMacroblock ( const HlmsMacroblock macroblock,
bool  casterBlock = false 
)
inherited

Sets the macroblock from the given pointer that was already retrieved from the HlmsManager.

Unlike the other overload, this operation is O(1). Calling this function triggers a HlmsDatablock::flushRenderables

Parameters
macroblockA valid block. The reference count is increased inside this function.
casterBlockTrue to directly set the macroblock to be used during the shadow mapping's caster pass. Note that when false, it will automatically reset the caster's block according to HlmsManager::setShadowMappingUseBackFaces setting.

◆ setSamplerblock()

void Ogre::HlmsUnlitMobileDatablock::setSamplerblock ( uint8  texUnit,
const HlmsSamplerblock params 
)

Sets a new sampler block to be associated with the texture (i.e.

filtering mode, addressing modes, etc).

Parameters
texUnitID of the texture unit. Must be in range [0; 16) otherwise throws.
paramsThe sampler block to use as reference.

◆ setTexture()

atlasParamsThe atlas offsets in case this texture is an atlas or an array texture

◆ setTextureUvSource()

void Ogre::HlmsUnlitMobileDatablock::setTextureUvSource ( uint8  texUnit,
uint8  uvSet 
)

Sets the set of UVs that will be used to sample from the texture unit.

Remarks
Calling this function implies calling
See also
HlmsDatablock::flushRenderables. If the another shader must be created, it could cause a stall.
Parameters
texUnitID of the texture unit. Must be in range [0; 16) otherwise throws.
uvSetThe uv set. Must be in range [0; 8) otherwise throws. If the datablock is assigned to a mesh that has less UV sets than required, it will throw during the assignment.

◆ setUseColour()

void Ogre::HlmsUnlitMobileDatablock::setUseColour ( bool  useColour)

Controls whether the value in.

See also
setColour is used. Calling this function implies calling
HlmsDatablock::flushRenderables.
