Having finished my Rendering tutorial series, I have now begun publishing tutorials in the Advanced Rendering category. While the Rendering series covered Unity's built-in rendering pipeline and standard shaders, the advanced tutorials go beyond that and cover more specialized functionality.
The first advanced rendering tutorial is Flat and Wireframe Shading. It introduces screen-space derivatives and custom geometry shaders, using then to apply flat shading and a wireframe effect to any mesh.
The second tutorial in the series is Tessellation. The concept of subdividing triangles into smaller ones is straightforward, but getting that to work on the GPU is nontrivial. We'll have to create a hull shader, a domain shader, and a patch constant function.
The third tutorial is Surface Displacement. It combines tessellation with vertex displacement to create more interesting surfaces. It's like parallax mapping, but better.
Tutorial four is Bloom. It covers the bloom post-processing effect, which can be used to make things appear to glow, or for other artistic effects.
Tutorial five is Depth of Field. This is a post-processing effect that simulates camera focus.
