I had to google TIN-algorithm to get a gist of what you talk about. It looks like the triangulation I've tried to figure out. I'm not getting passed the convex hull. I've writte a pile of code that hasn't been tested .. it's doomed. <BR>
I assume that you are working on the clouds that you collect with the lidar? <BR>
<BR>
The point 'painting' .. is that the Device.DrawPoints (or something eqvivalent, Draw.Point is not supported in Xna)<BR> <BR>

I usually deal with point clouds, which are<BR>> not gridded, so either I display just a set (cloud) of points, or I have to<BR>> run a TINning algorithm to make a surface to display.<BR>> <BR>> One of the issues I like to complain/whine about a lot is the lack of a<BR>> really good, standalone-portable, quality-scalable TIN construction library.<BR>> Having something like that is a part of my dream 3D geo engine library...<BR>> <BR>> -mpg<BR>> <BR>> <BR>> <BR><BR> </body>
