We have it running in 3D now.

It needs quite a lot of RAM but, hey, i think the result is worth it. Hoping for a 25fps version :)http://biterror.lo-res.org/2006/08/video.htmlnoreply@blogger.com (Aaron)0tag:blogger.com,1999:blog-31979398.post-115481788699279157Sat, 05 Aug 2006 22:25:00 +00002006-12-05T13:40:24.486-08:00Continued to experiment with the visualization together with a friend.<br /><br />Some very nice outputs. Even possible in stereo! (blue/green glasses needed).<br />Movies are coming... <br /><br />This show some gradient autodetection features.<br /><img src="image-00000-small.png"><br /><br /><br />This is a cut through the same wave file as below. <br /><br /><img src="image-00002-small.png"><br>cut through the same wave file<br>http://biterror.lo-res.org/2006/08/wave-calculations-2.htmlnoreply@blogger.com (Aaron)0tag:blogger.com,1999:blog-31979398.post-115439585281283511Tue, 01 Aug 2006 01:30:00 +00002006-08-03T16:03:02.706-07:00recently started to get interested in <a href="http://en.wikipedia.org/wiki/wave">wave equations</a>. Pantha Rei! Everything flows! Imagine yourself as a pure collection of wave functions - the sum of all wave functions of each of your atoms, electrons, neutrinos and quarks combined.<br />No matter anymore, just pure waves. :) Strange imagination for me. I can not quite grasp it yet but it definetely makes sense from the physics that i know.<br /><br />Some nice results were obtained by visualizing wave interference patters via volumetric rendering.<br /><br />Ten random point sources for some sound wave collide:<br /><img src="wave1.jpg" width=800><br /><br />the same wave but looking at it from a different angle with different colors:<br /><img src="wave2.jpg" width=800><br /><br />download the <a href="http://tema.lo-res.org/~aaron/waves/waves20060802.tgz">GNU GPL'ed source code (ANSI C)</a> for calculating the NxNxN cube. And use some software for <a href="http://en.wikipedia.org/wiki/Computer_Tomography">CT</a> such as <a href="http://www.cs.utah.edu/~jmk/simian/index.htm">Joe Kniss's Simian</a> for visualizing.http://biterror.lo-res.org/2006/07/waves-calculations_31.htmlnoreply@blogger.com (Aaron)0
