Ray Tracing

Visionaray – C++ ray tracing template library

Visionaray is a cross-platform ray tracing framework.

There’s also a viewer available. It supports a number of 3D file formats. The viewer is primarily targeted at developers, as a tool for debugging and testing.

This is free and open source software.

Features include:

  • Cross-platform: Intel CPUs, Nvidia GPUs, Xilinx FPGAs (work in progress). No duplicate code, all platforms targeted from the same C++ code.
  • High flexibility through kernel- and scheduler-based architecture. Kernels describe what a ray does, schedulers describe how a ray is spawned.
  • Built-in kernels: simple ray casting, “Whitted”-style ray tracing, “Kajiya”-style path tracing.
  • Built-in schedulers: simple (scanline, single-threaded), tiled (multi-threaded), TBB, CUDA.
  • User can write custom schedulers and kernels.
  • Built-in performance primitives: SIMD short vector library, fast SBVH builder and traversal, texture support, physically based materials, etc.
  • VR support: Visionaray comes with a plugin for the virtual reality renderer OpenCOVER.
