load()

bool Wizt::GLTextureTentacle::load ( const MemCore::RefPtr< MemCore::ChunkBase > & TextureData, RenderBasin::TextureFormat TF, int rank, const size_t * Dimensions, int TextureUnit = 0, RenderBasin::TextureStorageFormat TSF = RenderBasin::AutomaticTexture(), int level = 0, bool GenerateDoMipMap = false )

overridevirtual

Parameters

TextureData	actual data to be loaded
TF	The type of the texture
rank	The dimensionality of the data
Dimensions	The extension of the data in each dimension, must match the provided TextureData
TextureUnit	The OpenGL texture unit in which to load these data
TSF	The internal storage format of the texture, affects memory utilization.

setTextureParameter()

bool Wizt::GLTextureTentacle::setTextureParameter ( const std::string & name, const std::type_info & T, const void * dataptr, int multiplicity = 1 )

overridevirtual

Set a texture parameter.

Note that this call will not immediately issue any OpenGL calls. Rather it prepares the TextureTentacle such that the right texture parameters will be set at the right time.

Parameters

name	A textual specification of the render parameter from the list in http://www.opengl.org/sdk/docs/man4/xhtml/glTexParameter.xml or as otherwise documented in the implementation of some RenderContext.

Returns

true if the texture parameter could be set, false otherwise, for instance when the given name is an unknown keyword and/or not supported by the underlaying render context implementation.

Implements Wizt::RenderBasin::TextureTentacle.
