1st homework: Scattered data interpolation

Inverse distance weighting (IDW) with its basic form, the Shepard’s method and Modified Shepard’s method with limited radius of influence of each data point. Interpolate.exe reads standard input data (Console.ReadLine) and outputs floats to binary file output.raw. There is also an option to output byte binary file for visualization of the volume.

Compile c# with:

csc *.cs

Run interpolate.exe with basic method (command prompt, not powershell):

./interpolate < input1k.txt --method basic --p 2 --min-x -1.5 --min-y -1.5 --min-z -1  --max-x 1.5 --max-y 1.5 --max-z 1  --res-x 128 --res-y 128 --res-z 64

or modified method:

./interpolate < input1k.txt --method modified --r 0.5 --min-x -1.5 --min-y -1.5 --min-z -1  --max-x 1.5 --max-y 1.5 --max-z 1  --res-x 128 --res-y 128 --res-z 64

2nd homework: Path tracing

Physically based rendering path tracing framework with basic path tracing algorithm with Russian roulette for stopping and importance sampling of choosing ray directions, support for spherical light sources and Oren-Nayar material.
