   Shape Lines (Bezier, etc)
  Hi,I am looking for an efficient way to draw shape lines (B-spline or Hermite),and I want to be able to edit the control points while the application isrunning. I am thinking of using index/vertex buffers but I amworried that it might get heavy, like was written in Microsoft DirectX newsgroup. I am wondering if there are any ways to make it more efficient? I thought ofusing vertex shader but since I need the values of the curve to perform otherthings, I am afraid that is a little bit impossible. I am wondering ifsomeone has had the same problem before and could point me how to best overcomethis problem? Sindharta T.
