From StockChartChallenge:
This remarkable fast applet (http://anfyteam.com/anj/voxel/anvoxel.html) shows a synthetic landscape, that is dynamically rendered as a fly-by movie.
The real challenge is now, to extend this voxel engine to a DataMusicVoxelApplet, being attractive for
C-source and a DLL, prepared for VB6 voxel experiments, can be found at http://www.ur.co.nz/flyby.htm. I don't know yet, whether this code is related with the code of the above mentioned Andrea "6502" Griffini.
Another java source for voxel software is http://www.lynx.ch/contacts/~/thomasm/voxel/default.html
