By studying the famous 'RayTracing' series, I tried to write down my own Ray tracing renderer, which currently supports following functions below:

• Path tracing using monto carlo integration
• materials rendering include:
  • lambertian material
  • perlin noise texture
  • image texture mapping
  • mixture densities material

• tidy my code
• path tracing optimization
• change the saving file from 'bpm' to 'png'
• change the input file by reading '.obj' file
• change the basic rendering unit to triangle and compare the performance

reference: tiny renderer, nori, PBRT

Rendering results are as follows:

RayTracingInOneWeekend final output with 500 spp

RayTracingInOneWeek final output with 20000 spp

RayTracing: Rest of your life with 10000 spp(also as a cornell box)
