In this tutorial we incorporate our first shader stage into the 3D pipeline: the pixel shader stage. We also explore some basic example pixel shaders (more heavy-duty stuff to come later).

The tutorial video is on YouTube here.
- What is a Pixel Shader and why is it used? 0:20
- We want to make color mapping of the triangles in the rendering pipeline configurable
- One way is to use templated function objects (functors) as "plug-in" code
- These functors determine the color of the pixel based on their input
- Refactoring of the
gfx.PutPixel(...)function inPipeline.h<code> 2:04
