Hi,
I have a data set consisting of xyz coordinates as floats, measured
by an imaging lidar. The scenes I work with provide irregular sampling
of tree canopies, tree trunks and portions of the forest floor. For
example, I may have measurements of the north side of a tall tree from
ground level to 4 meters, a gap, then measurements from 6 to 12
meters, etc. up the length of the tree. Voids in the measurements are
the result of occlusions in the foreground. Currently, I represent
every xyz measurement of the tree trunk as a separate square polygon
and besides being horridly inefficient, the resulting point cloud of
squares looks pretty rotten to boot. I would rather represent each
illuminated section of the trunk as a polygon since I believe it would
not only look better but also be far more efficient to render due to
the large number measurements in the data set.
Any suggestions on how to approach this? Any help would be greatly
appreciated.
Thanks,
Bill
