Hey all,
To get around the issues of curve3d matrix size I'm hoping to use multiple curve3d objects to create one surface.
The biggest problem I'm having is makes the curve surface seamless. Even with variable overlap between "patches" I always see the seams. :(
So if the max matrix size bug could be fixed, or a method of seamlessly joining curve3d objects would be great...
4x 8x8 curve3d's perform fine on the laptop.. (have not tried on linux due to a numarray/py issue)
Any hints would be appreciated.
Thanks all!

I don't recall using curve3d. Is it a cubic Bézier? if so, then the condition for a curve of coefficients $1..$7 to stay "C1" (that is, both continuous curve and continuous slope of the curve) is to have $4-$3 = $5-$4 (for all x,y,z). Is that right? I mean that's I recall from drawing Béziers with CorelDraw, Gimp, Sketch, etc. right? (they enforce that so that moving $3 also moves $5 so that $3,$4,$5 is a straight line of equally spaced points)
If the above hint is right, then can you apply this to _bicubic_ Béziers instead ?
