Hi Ranjan, this is a non trivial problem. perhaps you search the web for alpha-shapes and molecular surfaces to get an idea of how much math and science is behind this problem.
there are some fast c-algorithms around that can compute the surface for you. ;) you just would need to extract and visualize their output. cheers, Karsten > Am fairly new to Java 3D concepts.
