Daedalus Compute Samples

Tiny collection of compute demos, no wrapper around the compute APIs, tested on Windows/Ubuntu.

Features

  • ”proof of concept” demos
  • supports OpenGL, OpenCL, CUDA compute shaders/kernels
  • visualization with OpenGL (vbo/tex interop)

Mesh Deform

Cloth Simulation

Particle Simulation

Ray Tracing in One Weekend by Peter Shirley

PBRT ray-marching volume rendering, with single scattering lighting model

NVIDIA FleX Demo - DamBreak
