Projects

Here is an overview of some of the software projects I’ve worked on in my free time.

Unnamed voxel project

A small, simple voxel editor written in C. The goal is to bolt ray tracing into the editor eventually. I’m posting about it on bluesky occasionally: https://bsky.app/profile/nelarius.bsky.social.

`rayfinder`

path-traced-sponza

An interactive WebGPU pathtracer, implemented for desktop platforms using the Dawn renderer.

The goal was to learn how to implement path tracing for triangle meshes. The project contains

next event estimation for sampling the sun disk
a physically based sky model
using animated blue noise as sampling distributions
simple lambertian diffuse material

`imnodes`

imnodes

A small, dependency-free node editor extension for dear imgui. It features a small immediate-mode API similar to dear imgui itself.

Find it on github.

wrenpp::VM vm;
vm.beginModule( "math" )
.beginClass( "Math" )
  .bindFunction< decltype(&cos), &cos >( true, "cos(_)" )
  .bindFunction< decltype(&sin), &sin >( true, "sin(_)" )
  .bindFunction< decltype(&tan), &tan >( true, "tan(_)" )
  .bindFunction< decltype(&exp), &exp >( true, "exp(_)" )
.endClass()
.endModule();

vm.executeString( "import \"math\" for Math\nSystem.print( Math.cos(0.12345) )" );

A C++ binding generator for the Wren programming language. It utilizes modern C++14 metaprogramming features and is fairly compact as a result. You can use Wren++ to wrap any C++ function or class in Wren code. Wren++ also provides access to Wren code from C++.

I wrote a small tutorial on its usage here.
