Other usage issues

Hi all,

How have people found the performance and limitations of GeomAPI_PointsToBSplineSurface() for creating complex surfaces in terms of number of points that can used and accuracy?

Does anyone have any experience in comparing this to the SSP product or other methods?

I tried the Geom_Plate example method but it seemed to fail with a fairly small number of points.

Cheers,
Ads

Hi, Ads.
How many points you've tryed with Geom_Plate sample?
I'm looking to handle about 1..5e6 scattered points to construct surface, draw profile lines, construct isolines and so on.

I have never used either GeomPlate or SSP, but you might want to check out this thread:
