# [✓] Extract surface information from BSplineSurface?

GROUPS:
 Hello,I have generated simple surfaces using the BSplineSurface in the Graphics3D wrapper. While easy to visualize the resulting surface, its not clear how to extract the resulting surface coordinates for related processing. Any help would be appreciated.-Michael Sacks Attachments:

 Thank you - simple fix!To determine a 3D coordinate triplet on the surface, it looks like one must first determine the parametric coordinates (u,v) first. So, if I want to fit a 3D point cloud, I have to first convert that dataset to u,v coords. Doesn't seem any other way to do this in Mathematica.-M-
