Understanding What a Shader Model Does

A shader model is a system used to program different types of graphics and effects into one spectacular visual. The most common examples of things that are being generated by shaders are computer games. People initially thought that the shader had reached its maximum, but it was further enhanced to generate better graphics and visuals. Today, there are thousands of games that are being run by shader models; these are being made to look realistic.

There are two types of engines that are being utilized by games. These are the Direct3D and the OpenGL. Both of them are composed of three layers, which are unified by a shader model.

Vertex Shaders

Vertex shaders are responsible for giving computer games realistic colors, textures and object positions. Basically, it is the thing giving life to the games that millions of people play. It is the very beginning of the three way process.

Geometry Shaders

These are responsible for giving more depth and realism to the visuals that our computers produce. It is also responsible for holding, adding or deleting portions of a mesh. A mesh or a polygon mesh is what forms the models and characters of the game.

Pixel Shaders

A pixel shader is an advanced form of shader which was released in recent years. Its main focus is to provide better lighting effects to the visuals. It is also responsible for color toning and bump mapping, which gives more life to the graphics of computer games.

Unified Shader Model

This shader model finally compiles the three shaders mentioned above into Direct3D and OpenGL. Through this process, PC games as well as consoles, such as the XBOX360 and PlayStation3, will surely continue to rise.
