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>Aarontag:blogger.com,1999:blog-31979398.post-1155760308673463012006-08-16T13:27:00.000-07:002006-12-05T13:39:54.146-08:00<p>This is now the <a href="waves_rixc_small.avi">final version</a> 25fps of the video we played at an exhibition. <a href="http://www.calit2.net/~jschulze/projects/vox/">Deskvox</a> was used to calculate this movie.<br />Seems like cave like visualization is also possible... hm, let's see.<br /><br /><p><br />hurra, we made a first draft <a href=" http://tema.lo-res.org/~doron/doron_waves1.avi">video</a> with deskvox. It needs quite a lot of RAM but, hey, i think the result is worth it. Hoping for a 25fps version :)Aarontag:blogger.com,1999:blog-31979398.post-1154395852812835112006-07-31T18:30:00.000-07:002006-08-03T16:03:02.706-07:00recently 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.Aaron
