Raytracer

TODO

• fix lighting with cube
• add way to save/load a meshcollection
• make filepath different for different users
• Importance sampling
• Implement MSAA in camera
• Redo recursive ray intensity calculation (only one bounce per ray per hit, shoot multiple rays (samples) per pixel)
• Customizable FOV in Camera
• Use C++11 random library instead of rand()
• Remove hacky code DiffuseMaterial (l 25) (moved to HalveUnitSphereVectorGenerator::generateCosineWeightedVectorAroundNormal)
• Extend MeshGenerator (circle, square, sphere, cone, suzanne?, ...)
• Get OpenCV working
• Phong reflectance model
• pure absorbing material (ja dit kan al met een difuus materiaal met albedo 0, maar komaan, proper is t niet :p)
• use kd-tree or something similar for triangle stuff
• Parallelisation
• Add sun light
• add Reinhard tone mapping
• Russion roulette path termination
• next event estimation
• bidirection raytracing?
