VoxelToy is a simple Qt/OpenGL-based voxel renderer. The project is in early stages of development, and it currently implements:
- Progressive global illumination renderer (path tracing).
- Importance-sampled image based lighting.
- Lambertian BRDF for matte materials, Torrance-Sparrow for metals.
- Orbit and fly-through camera.
- Camera depth of field.
- Dense voxel representation in 3D texture, DDA traversal.
- Voxels can be seeded from input meshes. Voxelization carried out in GPU.
- Basic voxel adding/removing tool.
- Requires OpenGL 4.3.
- The project is developed in Linux (Ubuntu) using Vim/QtCreator. A CMake-based script for cross-platform building is provided, but no other platform has been tested yet.
