- Colloquium today, 4:00 - 5:00, Newton 201
- “An Elementary Construction of Tessellated Surfaces”
- Jonathan Pakianathan
- Extra credit for summaries
- I’m out of town Friday (March 6)
- “Class” will be on-line exercise in designing next ray tracer
- I will moderate remotely
- Specular reflection
- Phong model: specularly reflected light falls off sharply with
angle away from that of perfect reflection
- Functions that compute outgoing intensity from incoming considering angles called Bidirectional Reflectance Distribution Functions aka BRDFs
- Phong model: specularly reflected light falls off sharply with
angle away from that of perfect reflection
- Shadows
- Light sources
- Point sources
- Areal sources have non-zero area
- Require integrating incoming light over angles subtended by light
- What have I glossed over?
- What coordinate system do you do shading calculations in?
- Coordinate systems and shading
