This toolbox is very useful. It can improve many problems in my applications. However, it seems some small bugs when I evaluate the derivative of nurbs curves/surfaces.
In the file "nrbderiv ":
this file call the function "bspderiv". If the weights of the original nurbs curve/surface are equal ( example: the weight = 1 at each vertex ), this weights of nurbs curve/surface vanish after call bspderiv in file nrbderiv.
Maybe, we should revise the file "nrbderiv" before calling the function "bspderiv" to preserve the original weights.
I have a set of points say 300 something following the outline of cerebral aneurysm. I want to smooth this curve using the NURBS tool box provided here. How do i use this ? Where do I give my input? I just need a Bspline fitting to the data I have i.e. effectively to smooth the outline of the trace I have. Help me out..
Thanks!
