<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2> Thanks for your info. It works well
using the two examples you provided. Now I may ask do you know how to
convert 3D height map (generated from 2D image using shape from shading) to
the XML file?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2> Thank you. </FONT></DIV>

<DIV>Dongqing,<BR><BR>I don't think you will get the results you are looking
for with that method. It is assuming the meshes are strict subsets of each
other. I'm assuming you are looking for a nice manifold surface output. I put
together an example here: <A
href="http://www.rpi.edu/~doriad/VTK_List/SurfaceStitching/">http://www.rpi.edu/~doriad/VTK_List/SurfaceStitching/</A><BR><BR>There
are two surfaces which are overlapping synthetic LiDAR scans of a discrete
sphere. Using Stitching.cpp I took SphereScan1.vtp and SphereScan2.vtp and
produced Stitched.vtp. You can see by looking at Stitched.vtp that the two
surfaces are simply naively combined rather than "stitched".<BR><BR>I think
this is quite a useful thing to be able to do (namely to create 3d models from
real life objects using real LiDAR scans). There are some volumetric methods
for surface stitching (<A
href="http://www-graphics.stanford.edu/software/vrip/">http://www-graphics.stanford.edu/software/vrip/</A>).
I've been looking at trying to get something like this into VTK but it's quite
a project. Has anyone done anything similar to this with VTK and care to
share/contribute it?<BR><BR clear=all>Thanks,<BR><BR>David<BR>
