# Sparse Voxel Octree
A GPU SVO Builder using rasterization pipeline, a efficient SVO ray marcher and a simple SVO path tracer.  
[Vulkan version](https://github.com/AdamYuan/VulkanSVO) with multiple performance improvements is working in progress.

## Compilation
```bash
cmake . -DCMAKE_BUILD_TYPE=Release
make
```
