Member Function Documentation

bool GLTextureHandler::bindImage	(	ImagePtr	image,
		const ImageSamplingProperties &	samplingProperties
	)

overridevirtual

Bind an image. This method will bind the texture to an active texture unit as defined by the corresponding image description. The method will fail if there are not enough available image units to bind to.

Reimplemented from ImageHandler.

static ImageHandlerPtr GLTextureHandler::create ( ImageLoaderPtr imageLoader )

bool GLTextureHandler::createRenderResources	(	ImagePtr	image,
		bool	generateMipMaps
	)

overridevirtual

Create rendering resources for the given image.

Reimplemented from ImageHandler.

int GLTextureHandler::getBoundTextureLocation ( unsigned int resourceId )

Return the bound texture location for a given resource.

int GLTextureHandler::getNextAvailableTextureLocation ( )
