<DIV>Thank you David</DIV>
<DIV>not only a single lidar scan, i scan it from everywhere</DIV>
<DIV>the point cloud include the top bottom even inside the big fisure</DIV>
<DIV>i change the alpha, the best result that delaunay3d get is ok but with some triangle missing and some edge isolated(without triangle)<BR>--- <B>09å¹´6月24日，周三, David Doria <I><daviddoria@gmail.com></I></B> 写é“：<BR></DIV>

<DIV>Hi everyone</DIV>
<DIV>this is the first time i use this mail list</DIV>
<DIV>I hope it work</DIV>
<DIV>please reply me thank you very much</DIV>
<DIV> </DIV>
<DIV>I have a point cloud in 3D scanned from a surface of an object</DIV>
<DIV>I want to create the mesh(triangulization) for this surface</DIV>
<DIV> </DIV>
<DIV>I tried vtkSurfaceReconstructionFliter, but the output is not a mesh</DIV>
<DIV> </DIV>
<DIV>I tried vtkDeluanay2D but it project my point to a 2D plan</DIV>
<DIV>and my points is on a complex surface(for example a flower) </DIV>
<DIV>i cannot find the project function</DIV>
<DIV> </DIV>
<DIV>i tried vtkDeluanay3D it will create the mesh in side the object</DIV>
<DIV>I set alpha = 0.2 it will remove most the edge inside but it also remove the edge on my surface</DIV>
<DIV>Someone has some good idea?</DIV>
<DIV>I thing it is problem very commun create a mesh for a surface </DIV>
<DIV>I see some CAD software do it perfectly i know there must be a solution</DIV>
<DIV> </DIV>
<DIV>Thank you very much for you attantion</DIV>
