swf null Aug 2002 My first programmed simulation. I later made this into a modified Pong game. images/BallAndToys.swf images/BallAndToys.jpg 600 450 swf null null Just a bunch of randomly blinking smiles. images/Blinkers.swf images/Blinkers.jpg 320 240 swf null August 2002 I was learning how to detect object collisions when I made this simple game. I was surprised at how long this game amused some people for. images/HitAreaGame.swf images/HitAreaGame.jpg 600 450 swf null August 2002 My version of the classic Pong Game. I made this when I had a hand injury that kept me from working or climbing. images/SuperPongGame.swf images/SuperPongGame.jpg 600 450 swf null Dec 2003 An experiment to learn how to animate particles. images/ink_drops.swf images/ink_drops.jpg 500 310 swf null null A random motion experiment where the direction is changed randomly. images/mice.swf images/mice.jpg 500 310 swf null null Adjust the Speed, Amplitude and Frequency to change the sine wave form. images/oscilloscope.swf images/oscilloscope.jpg 600 450 swf null Feb 2003 An attempt to simulate the random but fluid motion of falling snow... although this motion is not so random, each flake's motion is defined by a sine wave. images/snow.swf images/snow.jpg 600 200 swf null null Kind of like the snow but in reverse. images/bubbles.swf images/bubbles.jpg 90 240 swf null Sep 2002 Another particle with forces experiment.

This one uses random changes to acceleration. images/motionNode.swf images/motionNode.jpg 500 310 swf null null A random motion experiment where the acceleration is changed randomly although there are also some forces between the nodes. This one also includes some practice with dynamic drawing in flash. images/starNode.swf images/starNode.jpg 500 310 swf null null Not too exciting other than how the cursor's tail end is sort of dragged along behind the tip. I saw something like this in a game somewhere and just had to try and do that myself. images/pointer.swf images/pointer.jpg 600 450 swf null null Click and drag in the screen to create some sparks. Notice how the sparks pick up momentum from the mouse? images/sparks3.swf images/sparks3.jpg 500 310 swf null null Move the mouse around to create some sparks. Notice how they bounce off the sides and pick up momentum from the mouse? images/sparks2.swf images/sparks2.jpg 500 310 swf null null Move the mouse around to create particles that will dissolve into the scene. images/sparks.swf images/sparks.jpg 500 310 swf null Feb 2004 This was an experiment to try and program various kinds of physics such as gravity, shadows, particles, bouncing, rolling and friction all into one simulation.<br>You can click on the ball to move it around and throw it. You can also move the sun but be careful, it will burn the ball if they touch. images/bounce_roll.swf images/bounce_roll.jpg 600 450 swf null Feb 2004 Just playing with random motion and fake 3D effects. images/choosingAndMove.swf images/choosingAndMove.jpg 500 310 swf null Feb 2004 Just playing with random motion and fake 3D effects. images/choosingAndMove_1.swf images/choosingAndMove_1.jpg 500 310 swf null null Learning so simulate chain links. This algorithm almost works... if you watch for long enough the chain links start to stretch out. I believe this is due to rounding errors in the calculations. images/chain_research.swf images/chain_research.jpg 500 310 swf null Apr 20, 2008 Was talking to my friend Ronald Gagne about some astro physics and got inspired to do another gravity simulation like the <a href='index.htm?10' >first one</a> that I made but with more complexity and physical accuracy. The orbits seem fairly stable at first but if you watch for long enough, interferences occur and the orbits change... often the smaller moons get flung off by the more massive planets. You can also try playing God by clicking the planets and moving them around... however this is likely to cause chaos. Refresh your browswer to re-start the simulation. <br><br>Note, this simulation is somewhat processor intensive and may slow you computer down if you are trying to do other things while watching this. images/L_080420_Gravity_Sim_1.swf images/S_080420_Gravity_Sim_1.jpg 600 600 swf null Apr 30, 2008 This little creature loves to to sit on his little green cross. When the cross moves, he desperately rushes over to its new location. You can move the cross by clicking on the screen although if you wait it will move randomly. This was an experiment with my new Tracer class for capturing and drawing the creature's motion path. This also uses a new navigation algorithm that steers the little guy to his goal. images/mouse_chaser.swf images/mouse_chaser.jpg 413 300 swf null Apr 30, 2008 Another experiment with my new Tracer class. These snakes randomly move around the screen. If you click repeatedly you should capture their interest. images/swimming_worms.swf images/swimming_worms.jpg 413 300 swf null May 6, 2008 Another experiment with my Tracer class. Here the entire graph scales to fit on the screen as it grows over time. Note: this may use up your memory and slow down your computer if you let it run for a really long time. images/stockMarketGraph.swf images/stockMarketGraph.jpg 400 240 swf null May 6, 2008 Another experiment with my Tracer class along with a my new Tracker class that moves the camera (_root movieclip) to follow a point. Notice how the camera lags behind the dot a little bit? This is achieved using a virtual spring and damper. Note: this may use up your memory and slow down your computer if you let it run for a really long time. images/Tracker.swf images/Tracker.jpg 500 310 swf null May 11, 2008 Modified my <a href='index.htm?24' >gravity simulation</a> to include tracers. You can still play God and move the planets around with the mouse. Note: This simulation uses a fair bit of processing power and may slow your computer down if you're trying to run other programs while watching this. images/080511_Gravity_Sim_1.swf images/S_080511_Gravity_Sim_1.jpg 600 600 swf null June 8, 2008 This is an example of some of the vector objects that I recently created to help with calculations in a lot of my simulations. The blue arrows represent generic vectors (objects with a magnitude and a direction). The red arrows are exact copies of the blue vectors only stacked from tip to tail creating a visual form of vector addition. The green arrow is the resulting vector from the addition. These tools can be used to add up a series of forces on an object and calculate its net acceleration.<br> <br> You can click and drag in any of the 4 quardants to change the angle and length of the vectors; moving the mouse left and right changes the angle while moving it up and down changes the length. The top right quadrant controls all vectors while the other quadrants each control a single blue vector. The white boxes control the speed at which the vector rotates. <br> This was partially inspired by a discovery that I made at work where I came up with a method of using vectors to easily visualize/analyse/choose dimensional tolerances for engineered parts. images/080608_vectors.swf images/080608_vectors.jpg 450 450 swf null Mar 31, 2009 images/090331-Ease-in-Ease-out.swf images/090331-Ease-in-Ease-out.jpg 550 400 swf null May 9, 2009 the ecliptic) displayed as a grid centered on the sun. I find it quite interesting to see the sky this way. I might try to do a nicer version of this at some point.
