Member Function Documentation

void Ogre::GpuNamedConstants::generateConstantDefinitionArrayEntries ( const String & paramName,

const GpuConstantDefinition & baseDef

)

Generate additional constant entries for arrays based on a base definition.

Remarks:
Array uniforms will be added just with their base name with no array suffix. This method will add named entries for array suffixes too so individual array entries can be addressed. Note that we only individually index array elements if the array size is up to 16 entries in size. Anything larger than that only gets a [0] entry as well as the main entry, to save cluttering up the name map. After all, you can address the larger arrays in a bulk fashion much more easily anyway.

static bool Ogre::GpuNamedConstants::getGenerateAllConstantDefinitionArrayEntries ( ) [static]

Indicates whether all array entries will be generated and added to the definitions map.

void Ogre::GpuNamedConstants::load ( DataStreamPtr & stream )

Loads constant definitions from a stream, compatible with GpuProgram::setManualNamedConstantsFile.

GpuProgram::setManualNamedConstantsFile

void Ogre::GpuNamedConstants::save ( const String & filename ) const

Saves constant definitions to a file, compatible with GpuProgram::setManualNamedConstantsFile.

GpuProgram::setManualNamedConstantsFile

static void Ogre::GpuNamedConstants::setGenerateAllConstantDefinitionArrayEntries ( bool generateAll ) [static]

Sets whether all array entries will be generated and added to the definitions map.

Remarks:
Usually, array entries can only be individually indexed if they're up to 16 entries long, to save memory - arrays larger than that can be set but only via the bulk setting methods. This option allows you to choose to individually index every array entry.

Member Data Documentation

size_t Ogre::GpuNamedConstants::floatBufferSize

Total size of the float buffer required.

Definition at line 152 of file OgreGpuProgram.h.

size_t Ogre::GpuNamedConstants::intBufferSize

Total size of the int buffer required.

Definition at line 154 of file OgreGpuProgram.h.

GpuConstantDefinitionMap Ogre::GpuNamedConstants::map

Map of parameter names to GpuConstantDefinition.

Definition at line 156 of file OgreGpuProgram.h.

bool Ogre::GpuNamedConstants::msGenerateAllConstantDefinitionArrayEntries [static, protected]

Indicates whether all array entries will be generated and added to the definitions map.

Remarks:
Normally, the number of array entries added to the definitions map is capped at 16 to save memory. Setting this value to true allows all of the entries to be generated and added to the map.
