A WebGL2 GPU path-tracer that runs in your browser.
Features physical materials by implementing the Enterprise PBR Shading Model (DSPBR)

Demo Viewer (glTF drag&drop)

Minimal Demo [ Code ]

• Browser-based, unbiased* GPU path-tracing
• Implements parts of the Enterprise PBR Shading Model (DSPBR)
  • Rough Metal & Dielectrics (opaque/transparent)
    Using energy preserving, multi-scattering GGX BRDF and directional albedo scaling for diffuse/sheen components
  • Sheen
  • Clearcoat
  • Emission
  • Iridescence
• Three.js scene compatibility
• Implements most of the new glTF PBR Next material extensions [1,2] and extension proposal pull requests (marked as PR below).
