A while ago I saw a question from a beginner in the world of CG about what would be the interpolation in shaders.

I think this topic can be interesting for those who are getting familiar with the topic.

Here I will talk about the basic concept behind the interpolation that is performed inside shaders.

The best analyser is the Radeon GPU Analyser, because it compiles the code, and you can see the shader instructions it generates, the amount of registers it uses, etc…

This is our starting point.
