Function Documentation

void _mesa_finish_render_texture	(	GLcontext *	ctx,
		struct gl_renderbuffer_attachment *	att
	)

void _mesa_render_texture	(	GLcontext *	ctx,
		struct gl_framebuffer *	fb,
		struct gl_renderbuffer_attachment *	att
	)

Called when rendering to a texture image begins, or when changing the dest mipmap level, cube face, etc.

This is a fallback routine for software render-to-texture.

Called via the glRenderbufferTexture1D/2D/3D() functions and elsewhere (such as glTexImage2D).

The image we're rendering into is att->Texture->Image[att->CubeMapFace][att->TextureLevel]; It'll never be NULL.

Parameters:

	fb	the framebuffer object the texture is being bound to
	att	the fb attachment point of the texture
