z buffer |
Also found in: Wikipedia, Hutchinson | 0.01 sec. |
z bufferA memory buffer in a graphics accelerator that is used to speed up the rendering of 3D images. It holds the depth of each pixel (z-axis), and as an image is drawn, each pixel is matched against the z buffer location. If the next pixel in line to be drawn is below the one that is already there, it is ignored. This is also known as "hidden surface removal." See graphics pipeline and graphics accelerator.

The pairing of the two technologies will leverage the unique features of the RAGE 128 card such as its power to handle advanced visual effects including, superscalar rendering, line and edge anti-aliasing, gouraud shading, twin cache, single pass multitexturing, perspectively correct texture mapping, mip-mapping and z-buffering and double buffering," said Ed Grondahl, Vice President of Product Marketing of ATI. Incorporating powerful 2D and 3D rendering engines, cached local texture memory, and on-chip DMA, VGA and setup, the REALimage 2000 architecture supports any combination of robust graphics features (lighting, Z-buffering, alpha blending, window clipping, etc. Hardware 3D acceleration features include rasterization, texture mapping, double buffering, 16-bit Z-buffering and an integrated geometry set up engine. |
