Micro simple software rasterizer in a single C++11 header file. Does not use OpenGL. Pure C++11.

Mostly useful as a way of teaching how the rendering pipeline in hardware works.

A day ago, I saw this post Asking how to create a software renderer.

I started writing my response, and it looked something like this:

One should not create a software rasterizer unless they are giant masochists. However, if you were to do it, and first you need to ....

After a while I stopped. After writing my tutorial on how to make a C++ rasterizer in english, I realized it was nearly unreadable.

New idea: I'll just write the tutorial in pseudocode. Then, I looked at the pseudocode. It was unreadable because it wasn't quite a language

New idea: I'll write the skeleton of the header with comments explaining what to put in the code! I did this.

Surely you can see where this is going.

I ended up actually filling in the code, and implementing a simple rasterization pipeline all in one C++11 header standalone header file. The interface is similar to a dramatically simplified version of OpenGL2.0 with shader support, that is only capable of drawing interleaved arrays of vertices from index buffers.

There are a couple examples showing how you use it, and I'll add comments or a tutorial to explain the code at a later date.

It needs Eigen3 for the main header, cmake to build the examples, and CImg (to display) the animation and texturing example.
