The Lead (Rust) Renderer

This is an experimental render taking certain inspirations from the Nori renderer. I plan to follow the PBR Book (3ed) in my pursuit to create a Pathtracer.

I initially started this project in C++, but I quickly realized that rather than learning what was going on behind the scenes, I started copying code verbatim, or with minimal changes. What did I do next? Why I switched over to Rust! With its borrow-checker and type-system I hope to better learn how to manage different coding patterns accross different languages.

Current To-Do list -

• Move away from Nori towards a more PBR-like implementation Since it is in Rust, the implementation is fundamentally different

• Add Geometry stuff (coordinate systems, vectors, points, rays, b boxes, transformations and interactions)

• Add animated transformations

• Add Shapes

  • Sphere

  • Cylinders, Disks

  • Quadrics, Curves

  • Triangle Meshes

  • Subdivision Surfaces

• Add Primitives interface

• Add aggregates Bounding Volume Heirarchy

• Add Spectra and Color stuff

• Add Camera models

  • Orthographic camera

  • Perspective camera

  • Environment (panoramic) camera

• Add samplers

  • Stratified sampler

  • Other samplers

• Add Film and Writer

• Add BxDFs

• Add textures (procedural and images)

• Add Volumes!!!!!!

• Add Light sources

• Create Direct integrator

• Create recursive Path integrator

• Create Volume Renderer

• Create Bidirectional Renderer

• Create Photon Mapping integrator (maybe)

• Add parallelism

• And much much more....

Note - This list of to-dos is NOT exhaustive it is just what I could think up of right now
