Meshing around the outside of a circle

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?

Thanks.

I don't know if this could be theoretically done, except by interpolating on an infinitely fine mesh. But that's just a seat-of-the-pants judgment, and there could be a way that did not come to mind.

I'm not an expert at this, but I did work on 3D models using patch and isosurface. Have you considered using these? I could generate 3D models and export it to CAD packages as a .stl file using the patch command.

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
