Mesh - Diagrid - Perforations- Gradient

Hi, I am a new user of grasshopper. I have a mesh imported from maya. I am trying to subdivide this mesh into diagrid and generate series of perforations based on the diagrid. and there would be a gradient in this diagrid (size). Now my main issue is, 1, is it possible to convert this mesh into surface in rhino; 2, is it possible to do it in rhino or it should be done in maya w/ maya paint and script? (which I find here, but not sure how it was achieved [http://computationalmatter.com/P-aintermetric]

Please let me know if there's any suggestions. Thanks
