ZillumGL

Zillum Renderer based on GLSL compute shader. [The CPU version] [Relevant blog posts]

Features

• Multiple integrators

  • Single-kernel naive-schedule path tracer (with MIS)
  • Single-kernel naive-schedule adjoint particle tracer (light tracer)
  • MIS-weighted (s = 0, t = any) + (s = 1, t = any) + (s = any, t = 1) integrator (triple path tracer)

• Multiple BSDF models including Disney Principled BRDF

• Multiple-threaded BVH from Implementing a practical rendering system using GLSL

• Environment map importance sampling (path tracer only)

• Interactive

• A simple Sobol sampler

• XML scene file

Currently or potentially working on

• Ray regeneration / streaming

• GPU BDPT

• GPU BVH construction

• A scene editor
