WebThe algorithm works by sequentially executing the following steps: 1. For each pixel position (x,y) a. Set the frame buffer locations to the background intensity. b. Set the z-buffer locations to zmax=zmin the minimum of available depths. 2. For each polygon (object surface) in the scene. WebThe depth buffer algorithm illustrates several features common to all hidden surface algorithms. First, it requires a representation of all opaque surface in scene polygon in this case. These polygons may be faces of polyhedral recorded in the model of scene or may simply represent thin opaque 'sheets' in the scene.
