You can append the two meshes with vtkAppendPolyData followed by a<br>
vtkCleanPolyData to remove duplicate points.<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>
