• Monte Carlo path tracer
  • Next Event Estimation
  • Russian roulette
  • Surface lights (spheres, quads)
  • Anti-aliasing (multiple samples per pixel)
• Structures
  • Plane, sphere, triangle primitives
  • Bounding volume hierarchy data structure (automatic construction and traversal)
• Shading
  • Diffuse, specular, dielectric material properties
  • Predefined materials: air, glass, water, metal, light source
  • Bitmap textures
• Pixel accumulator
• Skybox
• Mesh loader (OBJ)
• Scene switcher
• Moveable first-person camera
• Parallelized ray calculation

To do

• Improve render time per frame
• Add realistic camera (e.g. lens simulation for depth of field)
• Add more materials (e.g. micro-faceted)
• Etc
