• GUI using Dear ImGui
• Texture mapping for materials
  • Diffuse maps
  • Specular maps
  • Normal maps
• Shadow mapping for multiple directional lights
• Frustum culling with bounding spheres
• Voxel Cone Tracing
  • Indirect diffuse/specular lighting
  • Voxel-based Ambient Occlusion

Installation

Linux (Arch)

Depending on your GPU you first need to run one of these commands:

• NVIDIA - pacaur -S cuda
• Intel - pacaur -S intel-opencl-sdk
• AMD - pacaur -S amdapp-sdk

pacaur -S ocl-icd opencl-headers glew glm jsoncpp assimp
git clone --recursive -j8 https://github.com/bwiberg/conflagrant.git
cd conflagrant
mkdir build && cd build
cmake ..
make

MacOS

Does not work at the moment, but the following should be a good start

brew install glm jsoncpp assimp
git clone --recursive -j8 https://github.com/bwiberg/conflagrant.git
cd conflagrant
mkdir build && cd build
cmake ..
make

Windows...

Does not work at the moment, but the following should be a good start

Install these libraries (preferred way is to build from source). Add their base directories to the Path env. variable.

• GLEW
• GLFW3
• GLM
• Assimp - needs to be built from source
• json-cpp - needs to be built from source

Using Git for Windows (or similar), run the following:

git clone --recursive -j8 https://github.com/bwiberg/conflagrant.git

Next step is to build using CMake using one of the alternatives below:

• Use CLion as IDE (my preferred solution)
• Use cmake-gui.exe to create a project solution (Code::Blocks, Visual Studio, Unix Makefiles etc.)

Running examples

cd conflagrant/build/examples
./exampleN
