Romanesco is a GPU based Fractal Renderer developed using the NVIDIA Optix framework, it is still in a work in progress state but has been proven in production already!
- Progressive rendering of SDF (Signed Distance Field) surfaces using path tracing.
- Dump animated frames to .exr files, with useful data channels including surface normal, depth and orbit traps.
- SDF scenes are defined with simple hit kernels, these can be edited and compiled at runtime if Romanesco is built with a CUDA version that supports NVRTC. These scene hit functions can define any possible distance field, by combining primitives using distance operations like those found here.
- Render scenes in 360 for fractal environment maps!
- Cross-platform (tested on Windows/Linux, builds on Mac).
- Qt 5
- CUDA 7.0
- Optix 3.8.0 (other versions are untested, may require different CUDA versions)
- [Optional] OpenEXR
- [Optional] Boost
Note: The supported versions of CUDA/Optix will only work with up to VS2013 on Windows, if you are running a more up to date version of VS then install the build tools and force the toolset as described below
git clone --recursive https://github.com/TomMinor/Romanesco
Note: Make sure to add --recursive so all the submodules in dependencies/ are synced too
As specified in the Qt docs, you need to set CMAKE_PREFIX_PATH to Qt5's location.
If Optix, CUDA, OpenEXR or Boost cannot be found (if they are installed in a non-standard location), their locations can be appended to CMAKE_PREFIX_PATH.
Note: On Windows it is currently necessary to force a 64-bit build with CMAKE_GENERATOR_PLATFORM
mkdir build
cd build
cmake .. -DCMAKE_GENERATOR_PLATFORM=x64 -DCMAKE_PREFIX_PATH="D:\Qt\5.8\msvc2013_64;D:\ProgramData\NVIDIA Corporation\OptiX SDK 3.8.0"Use the toolset argument (-T) to force the 2013 compilers in a newer version of Visual Studio (such as community)
cmake .. -DCMAKE_GENERATOR_PLATFORM=x64 -T v120 -DCMAKE_PREFIX_PATH="D:\Qt\5.8\msvc2013_64;D:\ProgramData\NVIDIA Corporation\OptiX SDK 3.8.0"mkdir build
