Wooden PBR Engine is software ray-tracing researching engine for rendering 3D scenes based on C++17, SIMD Math Library, Data-Oriented ECS Design.
Technologies:
C++17, Data-Oriented ECS, Allocators, SIMD Math

Paper(RU):
https://drive.google.com/file/d/1mX7miJLeN_xeZ3ocKnfiUIN57I690-i9/view?usp=sharing

Implemented features:

  • Basic geometry shapes meshes generator
  • Exporter models data from some formats
  • Area lights, Infinite area light
  • Texturing
  • Billinear, Anisotropic samplers
  • Filter functions for reconstruction
  • Uniform, Stratified sampler
  • Uniform sampling different geometric surfaces
  • Dielectric, conductor fresnel
  • BRDF, BSDF, Micro-surface distribution
  • Linear Bounding Volume Hierarchy - hybrid building method based on surface area heuristic + fast morton code 3d volume separation
  • Multiple Importance sampling
  • Several materials (plastic, metal)
  • Blackbody emitters

In progress:

  • Metropolis sampling
  • Photon mapping
  • Volume rendering
  • Subsurface scattering
  • Multilayer materials
  • Scene parser

Libraries:
Data Driven ECS: https://github.com/Mishok43/WoodenECS
Math: https://github.com/Mishok43/WoodenMath
Allocators: https://github.com/Mishok43/WoodenAllocators

Based on:
Physically Based Rendering from Theory To Implementation
Computer architecture a quantitative approach
