Z Buffer Algorithm Or Depth Buffer Algorithm In Computer Graphics In Hindi | Z Buffer Algorithm Z-buffer, which is also known as the Depth-buffer method is one of the commonly used method for hidden surface detection. Depth buffer algorithm is simplest image space algorithm. The algorithm for the Z-buffer method is given below :. In computer graphics, z-buffering, also known as depth buffering, is the management of image. The computer would start (arbitrarily) with Polygon 1 and put it's depth value into the buffer.
