Detailed Description

Texture buffer represents a framebuffer with a multiple attached textures.

Note: Use of TextureBuffer requires use of gl_FragData[] in the shader

Member Function Documentation

◆ ensureTexture()

bool TextureBuffer::ensureTexture	(	video::ITexture **	textureSlot,
		const TextureDefinition &	definition,
		PipelineContext &	context )

private

Make sure the texture in the given slot matches the texture definition given the current context.

Parameters

textureSlot	address of the texture pointer to verify and populate.
definition	logical definition of the texture
context	current context of the rendering pipeline

Returns: true if a new texture was created and put into the slot; false if the slot was not modified

size	width and height of the texture in pixels
height	height of the texture in pixels
name	unique name of the texture
format	color format
