Programs

The following are small applications and demos made for various classes and projects.

Edge Test

This program implements a basic edge detection technique I’m studying for my thesis. It is mostly complete, but still needs a good linear depth buffer generator that can handle more than typical depth resolution. This application renders the edges of objects using a double pass render that uses Sobel’s filter on the normal and depth buffers.

GLSL Engine

This program was created to allow me to test different types of shaders for my thesis work. I made a wrapper for a lot of the OpenGL functionality relating to shaders. This program is still in development, but features three shaders to try out.

Ray Tracer

This contains the entire project for our Ray Tracing class. We kept adding new features throughout the semester. This ray tracer can recognize several types of shapes, materials, and cameras. There is a special file format it reads, designed by Professor Jason Hanson. Several example scenes and the scene specification format have been included with the project.

Controls

  • Open scene files via the menu
  • Adjust the options via the menus or use the shortcuts listed there
  • Choose one of several rendering types to begin ray tracing
  • If you want a larger image, just resize the window to the desired size

Requirements

  • Windows XP

Occlusion Demo

This was our occlusion graphics project. The wireframe boxes are rendered this way to prove that the boxes behind them are correctly occluded. The technique uses a special depth buffer and object buffer, all manually generated and mip-mapped to interact with the scanline renderer built into the framework.

Controls

  • Left-click and drag to view the scene from different angles
  • Avoid pressing other buttons, some framework functions may still be enabled and could lead to crashes

Requirements

  • Windows XP
  • OpenGL (basic support, comes with graphics drivers)
  • GLUT

Bump Mapping Demo

This was our bump mapping graphics project. It toggles between using normal textures and using a bump texture. The bump mapping effect was done manually in the scanline renderer framework.

AI

Zombie Attack

This program was built to learn about state machine-based AI. I simulated interactions between zombies, civilians, and police officers. Over a period of time, either all the population will turn into zombies (and rapidly die) or a portion of the population will remain with no zombies left.

A* Pathfinding

This is my implementation of A* pathfinding. The avatar can avoid objects as it travels from its starting point to the selected goal. There are lots of options available to customize the experience, all available through the on-screen buttons.

Curve Editor

This program contains implementations of most of the curve algorithm techniques I learned in our curves and surfaces class. These include several variations of De Casteljau for Bezier Curves, Interpolating Polynomials and Splines, and De Boor Algorithm for B-Spline Curves. There is also a mode for offset curves, a research project I did as part of my extra Masters-level requirements.

Controls

  • Left-click to set points
  • Right-click a point to delete it
  • Left-click and drag points to move them around
  • Use the side menus, buttons, and options to switch to different curve types and show data on curve construction
