PORTFOLIO

Project Description

This is an implementation of voxel cone tracing using the Vulkan Graphics API. This is rendered in real time using a GTX 1080 Ti GPU. Shadows, reflections and lighting all use a cone tracing algorithm that uses a 3d Texture as a voxel grid. The voxelization of the scene is performed in real time using the GPU’s geometry shader pipeline, which is stored into a 512x512x512 3D texture image.

The program was written in C++ and uses a custom 3d engine that I built including a math library, resource management and gizmo control for manipulating objects in 3D space. This project was an implementation of voxel cone tracing that I created from using a variety of online resources on the subject. It took a couple of weeks working full time to produce a working implementation with the Vulkan API. It does not perform well achieving 30~60 frame per second at 1440p resolution on a Nvidia GTX 1080 GPU but when considering what is going on this is still impressive.
