Hako-1.0 Massive Voxel Renderer
Everything is Voxel. A renderer for the Ray Tracing Camp 9 ( https://sites.google.com/view/rtcamp9/home ).
The short introduction: renderer_introduction
The short introduction audio: ずんだもん.wav
Video
Environment
AMD: Navi 10 or later ( vega10 or vega20 could work but I didn't really test it ) NVIDIA: compute capability 7.0 or later ( https://en.wikipedia.org/wiki/CUDA ) and need cuda SDK( 12.0 is used for the submission ) for nvrtc API
Assets
The final scene ( rtcamp9.abc ) that is used for the submission. It also contains a zbrush project, obj geometry files, houdini project file to generate "rtcamp9.abc".
Build
git submodule update --init
premake5 vs2022
Open MassiveVoxelRayTracing.sln and build.
