Welcome

This site contains many samples and prototypes that I have developed. All the code for the samples are available on bitbucket and people are free to do with it what they will. Ideally its best if you use the latest version of the Chrome browser, I tend to use the latest available APIs and features as I prototype and learn new subjects.

If you like what you see, why not chip in $1 to my patreon if you feel inclinded.

3D Fungi Prototypes

Fungi is a 3D / Game engine built from sratch using Javascript(ES6) and WebGL 2. I tend to do most of my 3D prototypes using fungi since its built around the purpose of rapid prototyping.

  19. Axis Aligned Lattice Deformer CPU Based on the Lattice created for unity3d by Barnaby Smith. Only difference is the math was redone in world space for my prototype.
  20. Axis Aligned Lattice Deformer GPU This is port of the previous example which ran on the cpu, but this one runs on the gpu through GLSL.
  21. Atmospheric Scattering Skybox Port of Felix Westin (@FewesW)'s Unity Example of Atmospheric Scattering.
  22. Octasphere A special type of sphere.
  23. Marching Cubes Editor During the progress of a project, I needed to be able to handle users selecting areas of a dual grid then procedurally generate meshes based on what the user selected. This was made as a proof of concept.

Three.js Prototypes

When doing professional work, I opt to use three.js instead of fungi.

  1. Wave Function Collapse Using 3D model tiles, the algorthm will connect them together to procedurally generate a road system.
