What is a list of common, cheap, real time rendering algorithms?
I am well aware of the existence of Blinn-Phong shading, which is a great tool when you are doing, for example, modelling algorithms and wan't to focus on the model. In this case a full BRDF result, ...

Is there some kind of Bresenham algorithm or equivalent for scanline rendering a rotated ellipse?
Back in the day when you often had to write your own low level rendering algorithms we all used to learn the Bresenham algorithms for lines and circles.
It was almost trivially easy to extend the ...
