Programming Assignment #3

Calculating Form Factors
Form factors were calculated using the following methods:
1. Monte Carlo with random samples: 16 samples per differential area on the receiver
2. Monte Carlo with uniform sampling: source was divided into 16 equal areas
3. Monte Carlo with jittered sampling: source was divided into 16 equal areas and centers were randomly perturbed
4. Point to disk
5. Analytic solution (point to polygon method)
Distance between polygons Monte Carlo / random sampling Monte Carlo / uniform sampling Monte Carlo / jittered sampling Point to disk Analytic solution (Point to polygon)
0.1
0.25
1.0
4.0

Notes:
- at large distances all methods perform roughly the same
- point to disk method works well if the distance is not too close
