What is the minimum of shader I need to use to run basic calculation on GPU?
- by Jinxi
I read, that the Hull Shader, Domain Shader, Geometry Shader and Pixel Shader can be used optional. So, is the Vertex Shader optional too? If no: What does a basic Vertex Shader look like? Just like a simple pass through? Is the Vertex Shader necessary to tell what kind of datastructure (Van Stripes or Meshes) are used? What can I do, with just the vertex shader?
Are the fixed functions working without any help of programming a programmable stage?
