Vulkan

This is a project I started to learn more about vulkan API. I started off just creating a regular glTF model viewer, but kept adding features, and it became more of a playground for exploration on rendering.

Renderers

Usage

VulkanApp.exe "path/to/your/model.gltf"

you can add another parameter to set the global scale of the scene, like so :

VulkanApp.exe "path/to/your/model.gltf" 0.01

Features

Renderers

It has 6 different “renderers” available :

Forward :

The simplest one, it just does forward rendering using the vulkan graphics pipeline. It’s using a pbr material shader. It also supports image based lighting, and directional lighting.

Deferred :

Simple Deferred rendering pipeline, just to understand how offscreen render targets work in vulkan It also supports image based lighting, and directional lighting.

Path Tracer RTX

A path tracer that uses the hardware acceleration features on new NVidia RTX gpus. It can also use Open Image Denoise to denoise the renders. It’s a simple path tracer, but still able to produce some good looking images!

Path Trace CPU

Well, that’s the same path tracer as the previous one, except it’s running on the CPU.

As it cannot benefit from hardware accelerated ray tracing, it’s using a custom BVH based on the great BVH series by Jacco Bikker.

Rasterizer CPU

As the title says, it’s a rasterizer that runs on the cpu that renders the scene. It really has a limited set of features : Only draws the triangles with a simple lighting algorithm.

It is based on tinyRenderer
