Inheritance diagram for GBufData:

Public Attributes
float	z
	The floating point depth value at the center of the fragment that is foremost in the sorted list of a-buffer fragments.
UBYTE	mtl_id
	The ID assigned to the material via the Material Editor.
UWORD	node_id
	This is the ID assigned to node via the Object Properties / G-buffer ID spinner.
Point2	uv
	UV coordinates, stored as a Point2.
DWORD	normal
	Normal vector in view space, compressed.
RealPixel	realpix
	Non clamped colors in "RealPixel" format.
UBYTE	coverage
	Pixel coverage of the front surface.
UWORD	rend_id
