3D Fundamentals Tutorial 9

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).

• 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 in Pipeline.h<code> 2:04
