bezier curves

[appdeveloper]

I'm trying to draw bezier curves to contour patients heads. I'm using the visual basic 2005 with Tao Framework and when i searched google i found several pages on this topic, but never managed to make them work. The best one i found was
http://www.ia.hiof.no/~borres/cgraph/math/bezier/p-bezier.html
but could not use glMap1f, since the last parameter is a pointer to the first element in the array.
Can anyone tell me how to draw bezier curves using vb2005?


My thanks in advanced

I don't know much about vb but in C# you'll need to pin the array.


GCHandle p=GCHandle.Alloc(points, GCHandleType.Pinned);
try
{
glMap1f(target, u1, u2, stride, order, p.AddrOfPinnedObject());
}
finally
{
p.Free();
}

As vb is a managed language, the code should (after translation to vb, of course) do the trick.
