I think you just need to run the result of the splat through vtkContourFilter.<br><br>I just made this demo - see if it does what you need:<br><a href="http://www.vtk.org/Wiki/Create_a_surface_from_Unorganized_Points_%28Gaussian_Splat%29">http://www.vtk.org/Wiki/Create_a_surface_from_Unorganized_Points_%28Gaussian_Splat%29</a><br>

<div>I want to creat a mesh form the points cloud on the surface</div>
<div>but Delaunary3D and surface reconstruction do not work</div>
<div> </div>
<div>So Finally i have to use the gaussian splatting</div>
<div>it seem correct</div>
<div>but what i got it's not a mesh</div>
<div>It's a a surface with thickness</div>
<div>So does some one know how to shrink this thickness</div>
<div> </div>
<div>It's a surface with thickness in polyData</div>
<div>I tried shrinkfilter it just shrink the size of the triangles, it doesn't work</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>

Or do you have points on the full 3d object (ie. front and back and top and bottom, etc)?<br>
