Graphics Projects


Here is a bunch of graphics-related projects I’ve worked on.

Hand sketches using Perlin noise

I write up some toy programs that use Perlin noise to simulate hand-drawn lines. It takes drawings represented by a series of lines and makes them more fluid and messy. Using this same technique, I wrote up some more demos that simulate lightning with animated Perlin-noise lines. Here is a simple example:

Ray Tracer
This was a joint project with Adam Stirtan who worked on ray tracer efficiency and model loading among other things.

2D-in-3D Rendering Engine

This was a university project I created in OpenGL which used GLSL for some of the rendering strategies. The engine featured Z-axis aligned billboard animated sprites, skyboxes, and selectable render strategies for tiles.

I decided to redo the engine using the Irrlicht Game Engine. So here’s what I had when I was working on it.

Portal Clone
A while ago I tried to make a portals system using the Java implementation of the Irrlicht Game Engine (Jirr)

    That ray tracer was probably the apex of fun I’ve had in University.
