What is this?
A step-by-step guide to implementing 3D game shading techniques such as SSAO, depth of field, bloom, normal mapping, fog, and screen space reflection/refraction for your own 3D game.

Beginners who want to learn practical shading techniques for 3D games, explained conceptually so the knowledge transfers across engines.What shading techniques does it cover?It covers texturing, Blinn-Phong lighting, Fresnel factor, rim lighting, cel shading, normal mapping, deferred rendering, fog, blur, bloom, SSAO, motion blur, chromatic aberration, screen space reflection/refraction, foam, flow mapping, outlining, depth of field, posterization, pixelization, sharpen, dilation, film grain, LUTs, and gamma correction.
