e52a6f0149 Tiling may be used as a preprocess to other techniques. This produces few artifacts when applied to scenes with polygons of similar size forming smooth meshes and back-face culling turned on. PowerVR Dreamcast List of Sega arcade system boards . Various screen-space subdivision approaches reducing the number of primitives considered per region, e.g. OpenGL Demo Codes OpenGL 2.0 Getting started with openGL on Linux and Windows : Click here OpenGL-Installation-Guide : Click here to download Introduction to C OpenGL Programming : Click here OpenGL vs. Problem Statement Performance based marks (indicative) Group IDs Alloted (by preference, FCFS) Details Preference No.
Optimising this process relies on being able to ensure the deployment of as few resources as possible towards the rendering of surfaces that will not end up being rendered to the user. Ray tracing attempts to model the path of light rays to a viewpoint by tracing rays from the viewpoint into the scene. In 3D computer graphics, hidden surface determination (also known as hidden surface removal (HSR), occlusion culling (OC) or visible surface determination (VSD)) is the process used to determine which surfaces and parts of surfaces are not visible from a certain viewpoint. ZBuffer hardware may typically include a coarse 'hi-Z' against which primitives can be rejected early without rasterization, this is a form of occlusion culling. F. Because the C-buffer technique does not require a pixel to be drawn more than once, the process is slightly faster. These objects are thrown away if their screen projection is too small.
