Vulkan Renderer

A rendering sandbox project intended to accumulate rendering features over time. Currently contains a few interesting features like deferred rendering, SSAO, and omnidirectional shadow maps as well as the ability to drop-in fragment shaders for postprocessing a la Shadertoy. Future iterations will add extra features like PBR and a basic UI to control the settings.

After modifying a shader, run the buildshaders.ps1 script from that shader's directory.

Currently only Windows build configurations are available; there is nothing platform-specific in the codebase so Linux build configs will be available eventually.


The first command line parameter is the name of a directory under the assets/models/ directory, the second parameter (optional) is the scale of that model, e.g.:

> Renderer.exe sponza 0.01

The .obj file to be loaded must have the same name as the directory itself e.g. models/sponza/sponza.obj.
