How 3D Game Rendering Works, A Deeper Dive: Rasterization and Ray Tracing

[Julio Franco]

In this second part of our deeper look at 3D game rendering, we'll be focusing what happens to the 3D world after all of the vertex processing has finished. We'll need to dust off our math textbooks again, grapple with the geometry of frustums, and ponder the puzzle of perspectives. We'll also take a quick dive into the physics of ray tracing, lighting and materials -- excellent!

After reading this, my head hurts with all the math. Very interesting stuff though and an enjoyable read for sure!

Very long and informative.

Voxels are the future thou!

Bottom line:
You can't play games with hi-quality graphics unless you know your math.
Go finish your homework!

Well if you want to make your own high-end 3D graphics engine from scratch, then you really need to know your math! Stay in school, folks
