• problems with quadric surfaces
• what is a surface shader?
• intro to writing surface shaders

Examples

• aov - secondary images
• layered shading
• using smoothstep
• using noise
• cellnoise
• flames and opacity
• texture channels
• rotating texture space
• repeating patterns
• high frequency aliasing
• edge effects (aka facing ratio)
• blobby shading effects
• shader to shader messaging
• fake sub-surface effects

• color by height
• polar coordinates & famous curves
• archimedes spiral
• regular polygon
• rosette
• trace sets
• selective occlusion
• point clouds, brickmaps & occlusion
• sierpinski point clouds
• nebula point clouds
• point clouds as accumulation buffers
• cellular automata
• 3d textures
• blobby sticky noise (rsl2)
• color by collision

Displacements

• what is a displacement shader?
• writing displacement shaders
• writing a smoke displacement shader
• displacement shading domes

Ray Tracing (very old style!)

• basic ray tracing - reflections
• basic ray tracing - refractions
• ambient occlusion
• surface names & ray names
