How to generate cross section from the boundary of a 3D point cloud?










0















I had a number of raw 3d points and a boundary for it, as well as the indices for those points on the boundary surface. As shown in the figure:



Left: Raw data points and its boundary; Right: points on the boundary surface



I want to make cross sections out of the boundary surface, at a different angle. How should I do this?



I looked at varies ways to make cross sections, including 2D interpolation and 3d contour plot for meshgrids, but none of them work since the point cloud is not a meshgrid.

          There are plenty of application that will generate an approximating mesh from a point cloud. Geomagic Wrap may be the easiest to use.
