| − | == Game Rendering Terms ==
| + | |
| − | It helps to understand the terms a graphics programmer uses, so you can talk the talk.

| − | ; GPU : The Graphics Processing Unit is a parallel processor for floating point operations; it's the heart & soul of your graphics card. It's mostly used for rendering calculations, but it can also be tricked into doing physics, particle systems, vertex skinning, real-time texture compression, etc. It frees the CPU (Central Processing Unit) to handle the rest of the processing tasks in the game like transforms, AI, sound, etc.

| + | |
| − | | + | |
| − | * ''"Offline rendering systems, such as those used in CAD applications, stress accuracy over frame rate... each frame of animation might take hours to render. Real-time renderers, like game engines and simulators, tend to emphasize constant frame rate to keep animations smooth and fluid, and are willing to sacrifice both geometric and texture detail in order to do this."'' - from the [http://www.extremetech.com/article2/0,3973,9722,00.asp ExtremeTech 3D Pipeline Tutorial] by [http://www.extremetech.com/author_bio/0,1728,a%253D234,00.asp Dave Salvator]
