Hey,
Ive really wanted to have crack with Radiohead's lidar data:
http://code.google.com/creative/radiohead/ (http://code.google.com/creative/radiohead/)
But ive have got no real help from anywhere on converting it to something useful.
My thoughts so far--
Method 1 (Hard):
There are loads of people on the youtube forum who have successfully done Delaunay triangulations on the data. If I could do the same and get an OBJ sequence i could use in maya, that would be amazing. There is a great program called qHull that does just this, but seems to require a science degree to understand. I found a mel script but couldnt get any meaningful results:
http://researchnodes.org/doku.php?id=examples:qhull:start (http://researchnodes.org/doku.php?id=examples:qhull:start)
and qHulls home
http://www.qhull.org/ (http://www.qhull.org/)
Method 2 (easier):
My next thought was meshing it in Realflow. This would either require writing filein importer for Realflow that converts each point to a particle, or a Maya equvilent (ive got a script to export maya particles to realflow).
Basically, if anyone has any ideas on getting the data as an animated mesh in maya, that would be freaking sweet.
Cheers,
