- Colloquium
- “Quantum Messages and Quantum Games”
- Monday, April 13, 4:00-4:50pm
- Newton 201
- Tom Cooney
- Department of Mathematics
- Louisiana State University
- Faculty candidate!
- Extra credit for summaries
- Hour exam 2 is next Monday (April 13)
- Material since 1st exam (e.g., shading, normals, reflection, Monte Carlo, etc.)
- Rules and format similar to 1st exam
- Project presentations start after exam (Wednesday April 15)
- Talk about what you hope to do, including examples of effect, why it’s interesting/important to math or graphics, what sources you’re looking at
- Aim to fit into about 10 minutes, including time for questions
- Side note: Matlab is more adamant than I had realized about not
sharing structures between references, so we can’t store
samplers in objects, have to store them in a separate global
vector instead
- Goal is to displace perfect reflection vector and use result as a
single sample for reflection
- Given a reflection direction and angular displacements Θ
and Φ, how do you calculate displaced vector?
if nReflections > 0 Calculate perfect reflection direction Get Θ from cosine sampler Get Φ from uniform distribution on [0, 2π] Generate reflection vector displaced from perfect by Θ and Φ [ reflT, reflObj, reflPoint ] = trace reflection vector if reflT is finite reflColor = calculateColor( reflObj, reflPoint in world coordinates, reflPoint in local coordinates, reflection vector, ... nReflections - 1 ) else reflColor = background color finalColor = finalColor + reflColor * coefficient of specular reflection else do Phong specular shading
