LiteRF

implementation of various radiance fields in C++

Build (CPU):

1. clone this repo:
   • git clone https://github.com/msu-graphics-group/LiteRF.git
   • cd LiteRF
2. clone submodules:
   • git submodule init && git submodule update
3. use Cmake to build project:
   • mkdir cmake-build-release && cd cmake-build-release
   • cmake -DCMAKE_BUILD_TYPE=Release ..
   • make -j 8

Build (GPU):

1. clone and build kernel_slicer (https://github.com/Ray-Tracing-Systems/kernel_slicer) in some directory

2. find and use VS Code config 'Launch (LiteRF)' in 'kernel_slicer/.vscode/launch.json':

   • you need to change all paths to your LiteRF sources
   • launch kernel_slicer with this config
   • you can make you own command line script if don't like VS Code configs
   • alternatively you can use bash/bat scripts:
     • bash setup.sh my/path/kernel_slicer/cmake-build-release/kslicer my/path/to/kernel_slicer (once)
     • bash bash run_kslicer.sh

3. build shaders:

   • cd example_tracer/shaders_generated && bash build.sh
   • or use record 'Build Shaders (GLSL, example_tracer)' in vs code config 'tasks.json': just press 'Ctr+Shift+B'

4. use Cmake to build project with 'USE_VULKAN' flag == 'ON':

   • mkdir cmake-build-release && cd cmake-build-release
   • cmake -DCMAKE_BUILD_TYPE=Release -DUSE_VULKAN=ON ..
   • make -j 8
   • Note that the program will seek for 'example_tracer/shaders_generated/kernel2D_RayMarch.comp.spv'
   • Therefore you have to run it from LiteRF root folder (what is done by default in VS Code config) or copy appropriate SPIR-V file to get 'cmake-build-release/example_tracer/shaders_generated/kernel2D_RayMarch.comp.spv'
