Shaders
summary
Hands‑on Unity shader course that moves from fixed‑function ShaderLab to custom Cg: downloads of UnityCGIncludes and built‑in samplers, implementation of ambient vertex shader, then per‑pixel Blinn‑Phong lighting, separate specular channel, textures via sampler2D, and per‑pixel lighting that compiles and runs in the editor. Demonstrates debugging pitfalls, uses modelview/inverse‑transpose matrices and up to four lights, and finishes with procedural effects like animated UVs and normal extrusion. Original session covered ~20% of slides; this version completes the examples.
