I can't find that option in my 1.2 build from last week. there's the BPA, a poisson reconstruction which are available in 1.1 and MLS (which I don't fully understand right now, I still have to read the corresponding paper) stuff in 1.2. the filter option "build surface from point" is not available in my build (2008-11-06). > third: my points-cloud is in the format > x,y,z,I > where I is the value of reflectance recorded by the LIDAR.

I have to deal with xyzrgb data (which in fact is xyzI, as yours) but as I'm not interested I converted that to an obj file by addingt a 'v ' in the beginning of every line. where dumb shell script for that is available upon request. I'm not quite familiar with the obj format, but I guess you could encode the color into that with a more elaborate shell script easily (depending in your scripting knowledge). cheers, norbert |
