Meshing around the outside of a circle
6 views (last 30 days)
I am creating a 3D plot using individual, unevenly spaced data points obtained around the outside of a rod. I am currently using the meshgrid and griddata funtions to interpolate and plot them around the outside contour of a circle representing the rod. However when I do, the delaunay triangles created in the mesh extend into and across the circle.
Is there a way to create the mesh such that it stops at the outer boundary of the circle?

Are you using the DelaunayTri class to generate the mesh? If so, you might be able to use the Constraints property. This documentation page has a nice example: http://www.mathworks.com/help/techdoc/ref/delaunaytri.inoutstatus.html
