Much of the stuff that is supposed to be on this page has not yet moved over from the old website.
I released version 1.2 of my Common Lisp Fourier Transform library today. It is significantly faster than the old version. On my MacBook Pro in SBCL 1.0.30 with a 512 by 512 by 16 array, version 1.2 takes 9.77 seconds where version 1.0 took 25.31 seconds. Version 1.2 consed 2.4M while version 1.0 consed 7.4M. [...]
In response to my recent post about genetically selecting cosine waves for image approximation, several reddit commentors said that I should just have taken the Fourier transform, kept the largest 100 coefficients and did the inverse Fourier transform. [I haven't run the RMS calculation on the result yet, but visually, it looks pretty nice with [...]
Earlier, I gave a sneak peek at some artwork for the children’s spelling game I am making for the iPhone. Here is a screenshot of the application (click for full size): I need to touch up the jaunty logo tiles in the upper left. Some of them are worse for the wear after the perspective [...]
My first iPhone app is a children’s spelling game. Development is coming along well now that I’ve discovered cocos2d-iphone. I should have screenshots to show early next week. For now, here is a sneak peak at one of the cards in the game.
Some time back, xach posted information about all of the interdependcies amongst the Lisp packages available on Cliki. He had toyed with a few visualization techniques. Me, I tweaked some old code visualization stuff I had written to output where everything was after it stabilized. Then, I tweaked my ray tracer to read that input [...]
