In computer graphics, A-buffer, also known as anti-aliased, area-averaged or accumulation buffer, is a general hidden surface mechanism suited to medium scale virtual memory computers. It …

The algorithm begins by sorting by depth. For example, the initial “depth” estimate of a polygon may be taken to be the closest z value of any vertex of the polygon.

Depth buffer method (Image space method) •It is an image-space approach. The basic idea is to test the Z-depth of each surface to determine the closest (visible) surface. •The depth values …

A buffer and a z-buffer are both techniques used in computer graphics to handle the visibility of objects in a scene. A buffer is a temporary storage area that holds pixel data before it is …

Z-buffer algorithms Associate a z value with each pixel Contains z for nearest point drawn so far OpenGL, Direct3D, etc. Where do we get the Z?

How can we emulate transparent objects? Geometry Processing. • Only Z-buffer the size of scan-line is required. A := A + {P in Scene : YMin(P)<=y}; A := A - {P in A : YMax(P)<y}; for each …
