I have a data set of (x,y,z) coordinates for several points that form a point cloud in the form of the bones in a human leg. I want to use nearest neighbor interpolation of these points in order to create a grid and eventually an stl file to export to solid works. Thanks

Five years later, but may still be relevant...
Try using the "boundary" function. You can input a point cloud of (x,y,z) coordinates and it will return the solid formed by them. You can graph it using "trisurf."
Hope this helps!

... it has lots of tools for creating meshes from various types of data.

Check the following file in mathworks file exchange...It will convert the mesh to stl file, which you can export to other wares..

I suggest you look in the FEX for John D'Errico's work on Alpha Shapes.

Darn, I get confused sometimes about what John has released or not. He has spoken of his code in the past, but it looks like he has not put it on the FEX.

You can also do it using tri and trimesh function:
example:
DefoNodes--> x,y and z coordinates of each Node
tri = delaunay(DefoNodes(1,:),DefoNodes(2,:));
trimesh(tri, DefoNodes(1,:), DefoNodes(2,:), DefoNodes(3,:),'EdgeColor','k');

Hi, Great writing! I have a question about using PointCab Suite. I read introduction of Point cloud to BIM on an article https://www.marsbim.com/blog/scan-to-bim-introduction-from-technology-to-the-bim-model/ and understand about PointCab Suite Revit. And I know that PointCab Suite is powerfull tool for point cloud modeling and easily manage .LAS files and covert it into .RCP format. But when to load that file in Revit, I received some issue on that process. Is there any other format to directly open point cloud files in to Revit? Thanks.
