Compute Shaders - Overview and theory

The compute shaders in both DirectX and OpenGL allow us to use the GPU in a way that is not pipelined as object->primitive->pixel.
In one sentence, what they allow you to do is dispatch an arbitrary number of GPU computing threads that operate in an arbitrary way on resources.

GR Graphics - Post Processing

The conceptually and temporally final step before display on the screen, which is also optional but practically ever-present in modern graphics, is post-processing.

Post processing is basically any processing that happens after you create a ready - to - display 2D image from your 3D model data. HLSL and GLSL gives you a very convenient place to perform that post processing in the pixel shader.

Deferred shading - Dealing with low precision normal artifacts

While the G-Buffer format I described at the previous post was quite workable, after careful examination, in close-ups, some artifacts DID pop up.


As in most "real" detective stories, the culprit is really the "obvious" candidate. Obvious?
