Hi Roger,




There is indeed a way to determine the number of vertices of the final PDM. The final mesh is created from the spherical harmonic description via icosahedral subdivision. The number of subdivisions will determine the number of vertices, and thus you dont have total control on what number of vertices to choose (see http://www.ncbi.nlm.nih.gov/pmc/articles...).

More about this here: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3062073/


I hope that helps.
Let us know.
