3d photorealistic rendering

first, the graphics fixed pipeline rendering processFirst set the way to observe the scene Setupthecamera (); Clear the depth cache clearzbuffer (); Set ambient light and atomization [if needed] setgloballightandfog (); 1. World scene level operation//Get visible object list potentiallyvisibleobjectlist = highlevelvisibilitydetermination (Scene); 2. Object triangular grid-level operations, render them for (all objects in potentiallyvisibleobjectlist)

the math problems involved can be seen by the Wolfram Mathworld:the Web's most extensive mathematics Resource. Code: such as the source code of the engine (Unreal, Klayge, etc.), open source demo/example (in recent years the Direct3D official example also has some paper implementation), Unity's Asset store, Shadertoy beta and so on. Engineering problems are usually not a single technical problem, need to consider the integration of multiple systems, as well as the work flow and other aspect
