Noun
z-buffer (plural z-buffers)
(computer graphics) A buffer for the purpose of tracking the relative depths of different objects in a scene and determining which are closer to the observer than others.
As Z-buffer implementations generally rely on fixed-precision depth-buffer registers implemented in hardware, there is scope for visibility problems due to rounding error. Source: Internet
It proved better than Z-buffer painter's type algorithms at handling scenes of high depth complexity with costly pixel operations (i.e. perspective-correct texture mapping without hardware assist). Source: Internet
Consequently, in contemporary interactive graphics applications, the Z-buffer has become ubiquitous. Source: Internet
The Z-buffer allows larger volumes of primitives to be traversed linearly, in parallel, in a manner friendly to modern hardware. Source: Internet
This is because of the size of the intermediate datastructures required during rendering—which can exceed the size of a Z-buffer for a complex scene. Source: Internet
This kind of algorithm can be easily integrated with many other graphics techniques, such as the Phong reflection model or the Z-buffer algorithm. Source: Internet
