Cloth Simulation / Soft Shadows / HDR

This is a basic cloth/spring simulation with a gravity force and an external wind force. The mass points and springs are read in from a mesh. Phong shading is used for the lighting. Soft shadows have been implemented using Variance Shadow Maps (as seen in GPU Gems 3) and a basic HDR has been implemented based on ATi's implementation of Paul Debevec's SIGGRAPH paper. C++ and HLSL are used.

Raytracer

This is a raytracer that implements phong shading, soft shadows, anti-aliasing, refractions and reflections. Learning how a raytracer works was always something I wanted to learn. Seeing how to implement offline graphics gave me a different perspective from real-time graphics and rasterization. This project uses C++ and Win32.

Inverse Kinematics / Hierarchical Bone Animation / Bezier Curve Path-following

This project combines hierarchical mesh animation and inverse kinematics. The mesh is read in from a .X file exported from 3DSMax. The key frames are manually interpolated using LERP and SLERP (the animation controller is bypassed). The model also walks upon a bezier curve at constant speed. Written in C++ with DirectX.

Sokoban Solver

This is a program that solves Sokoban using A*, written in C++. No fancy graphics here, all ASCII output. The purpose of this exercise was not A* specifically, but in finding a way to drastically limit the search space that is produced by the game of Sokoban. An abstracted A* algorithm was created, that made use of the Astar_node interface. This interface was then extended to the problem of Sokoban, with each node also representing the state of a Sokoban board.

Bezier Curves

A program to draw Bezier Curves, written in C#.

Computer Graphics - Bump Mapping / Texturing

A software renderer that does per-pixel lighting, texturing, and bump mapping. Written in C++, with some OpenGL helpers, but most functionality overridden for the sake of the project.

Hollow Point - 2nd Year Game

Student game from the 2007-2008 school year. On a team of four programmers, and four artists, I am the technical director for the game, and initially worked on the game architecture, and later focused on graphics. The game uses component-based object design, along with an event-based messaging system using a subscriber pattern. Graphical features I've implemented are: Instancing, Phong lighting, Animations, Post Processing effects, dynamic wall generation, and smoothed shadow maps. The game is programmed in C# using XNA Game Studio 2.0.

The following are Pre-Alpha screenshots (read: programmer art :) )

Trash Gordon - 1st Year Game

Student game from the 2006-2007 school year. On a team of four programmers, I am the technical director for the game, and primarily worked on the game architecture, which includes a component-based design, and event driven messaging system. The game is programmed in C++ using DirectX.

It's a space shooter, with a slight twist, you collect the debris of enemies that you have destroyed to use as a shield, or special attacks. There are three levels, and a myriad of enemies and bosses. As well as a killer soundtrack!
