REYES renderer in C++

complementary slides about the algorithm and the implementation: https://www.slideshare.net/DraganOkanovic/reyes-59489937

example renderer output	algorithm

Source code is divided as following:

• core/: responsible for systems independent of the reyes algorithm
  • aajob.hpp: multithreading management
  • backend.hpp: win api and opengl init
  • mem.hpp: memory management
• reyes/
  • settings.hpp: modifies behavior and data structures
  • pipeline.hpp: main rendering procedure and heart of the system
  • shape.hpp: main abstraction of the input
  • shading.hpp: abstraction of a material and shading system
  • grid.hpp: microgrid abstraction
  • scene.hpp: convenient data structure
  • camera/
    • scene.hpp: abstraction of the virtual camera
    • film.hpp: abstraction of the image's film
    • film/: different implementations of the film
  • lib/: different implementations of the core parts of the shading system
    • lights/
    • materials/
    • samplers/
    • shapes/
  • misc/: vector math and matrices

• basic buffer (1 sample per pixel)
• no bucketing
• no splitting and bounding (dice entire primitives, each and every)
• basic pipeline
• basic rasterizer

• transformations (translate, scale)
• dicing
• bounding and splitting
• entire reyes pipeline
• finalize quadrilaterals and triangles
• G-buffer
• improved memory management and speed
• geometry: plane, sphere, disc, cubic bezier patch, Utah teapot
• support for different materials (custom "shaders")
• texture samplers in "shaders"
• support for lights: directional, point

• threaded renderer
• improved memory managment
• A-buffer
  • stochastic (multi)sampling
  • transparency support
  • inject optimizations
• dof
• motion blur
• task (job) manager
• profiling
• bucketing
• (progress indicator)
• (camera; perspective and orthographic)
• (Klein bottle)
• (SH light)

• optimized memory layout
• (GP)GPU implementation
• (pseudo) real-time

• alogirthms for fixing cracks
• fix elongated micropolygons
• dice criterium different
• dynamic dicing

• shadow mapping
• additional post-processing effects
• animations
• materials (toon, phong, ggxD)
• additional geometry
  • catmull-clark subdiv
  • more bezier
  • nurbs (b-spline)
  • loop subdiv
• full Renderman specification
