This is a quick little demo that takes an image and does some neat warping animation on the screen with it. I was using this as a handy way to test and iron out bugs in a function I recently wrote. The function can read a polygon from a source image, and draw its contents to another polygon in another image. What makes it so useful is that those polygons do not have to be identical. I have already used it to implement a blitting function with transformations that is much faster than the one I wrote in college. It does have a few limitations. For one thing, although the polygons in use do not have to be the same shape, they do need to have an equal number of defining points (for instance, you could copy between any two triangles, but not from a triangle to a square). This could actually be changed if necessary, but I do not consider it so for now. The other (more significant) limit is that the polygon to which it's drawing must be convex (although the one from which it's reading does not need to be). That too could be avoided, but doing so would slow the function down. This demo is always drawing to a rectangle (the whole window), but is reading from a polygon that is transforming.

The file linked at the top contains the source code and a make file, having been written to work on the GNU/Linux platform. A good friend of mine was kind enough to compile this on his Windows machine for me, so if you're using Windows and would like to see the program in action, you can download it in this zip file.

This is a simple little demo of transformations being done with my new image manipulating algorthm. It has a bunch of heads bouncing and spinning on the screen. The heads depicted are actually a slightly modified photograph of an origami mask that I made some time ago. The only modification to the picture was the addition of pupils on the eyes.

This is a screensaver style of graphical demo that uses a 3D graphics library I wrote when I was in college. It shows a bunch of spheres bouncing around on the screen. The angle of the lighting can be changed by moving the mouse, and the number of balls increased and decreased by clicking on the left and right mouse buttons respectively. The program will end when you hit the escape key.

Another quick demo of my old 3D graphics library. In this case, there is a model of a red maple leaf on the screen, which can be rotated using the mouse.

A simple program that draws a cube on the screen and lets you rotate it by moving the mouse. The main purpose of this program is to demonstrate a function I wrote which draws textured polygons in three dimensions. This was written for Xwindows on the GNU/Linux platform using SDL.

This "zip" file actually has three different programs in it, each one demonstrating the same algorithm. It started out as a simulation of a series of wagons being pulled, and evolved into these more interesting toys.

This is a GNU/Linux version of the worm algorithm that I originally developed under MS-DOS. It uses Mesa, the Linux port of OpenGL, and runs on the Xwindows desktop.

A bunch of particles with colour-coded masses almost following the laws of gravity. You move the heaviest particle around with the mouse and the others will follow.

The Mandelbrot Set is a fractal which is named after Benoit Mandelbrot, the mathematician who first plotted out this set of numbers on a computer. The program here is my own rendering of that set.

This is another version of that same Mandelbrot set, written to work with Xwindows on GNU/Linux. It uses the Mesa graphics library and should port pretty easily to other platforms.

When I was in high school, I and a good friend of mine discovered screen savers (bear in mind that these were a new concept at that point). We both thought they would be fun to write and did so. This program demonstrates some of the ones that I wrote.
