SORT

Introduction

SORT, short for Simple Open-source Ray Tracing, is my personal cross platform ray tracing renderer. It is a standalone ray tracing program, while works well in Blender as a renderer plugin. Simliar to other open source ray tracer, like PBRT, luxrenderer, SORT is also a physically based renderer. However, since it is a solo project that I worked on in my spare time, it is way simpler comparing with its peers.

Features

Here are the features implemented so far:

• Integrator. (Whitted ray tracing, direct lighting, path tracing, light tracing, bidirectional path tracing, instant radiosity, ambient occlusion)
• Spatial acceleration structure. (KD-Tree, BVH, Uniform grid, OcTree)
• BXDF. (Disney BRDF, Lambert, LambertTransmission, Oran Nayar, MicroFacet Reflection, Microfacet Transmission, MERL, Fourier, AshikhmanShirley, Modified Phong, Coat, Blend, Double-Sided)
• Node graph based material system.
• Camera. (DOF)
• Multi-thread rendering.
• Blender plugin.
