Odin - A Vulkan-based Path Tracer

Odin is a path tracer that is written using the Vulkan API and compute shaders. Odin has been tested on an NVIDIA Geforce GTX 970 and Intel Integrated graphics GPUs.

Features

• Support for diffuse, caustic, and dielectric materials
• Tracing of geometry serialized in the OBJ file format
• A basic Bounding Volume Hierarchy using axis-aligned bounding boxes

Installation

Dependencies

Make sure you have CMake, the Vulkan API, and Boost's boost::program_options installed on your system. It is also important to have a compiler that supports c++17 to be able to compile Odin.

Building

1. Clone the repository - git clone --recursive https://github.com/tstullich/odin.git
2. Create a build directory and build

cd odin
mkdir build
cd build
cmake ..
make install

Odin should then be installed in the bin directory. Type odin --help for more information.

Future Work

Below is a list of planned features and improvements for Odin

• Rewrite BVH construction and traversal logic to use an SAH k-d tree
• Implement Multiple Importance Sampling
• Improve the compute and graphics pipelines to do batched rendering
• Update the camera model to use a view matrix
• Expand material support
• Add a GUI for tuning scene parameters at runtime (Dear Imgui)
• Move Vulkan header to use Vulkan-Hpp
