I fiddled around with the Ayam surface modeler and it's (old school)
openNURBS export, and after climbing a bit of a GUI learning curve and
hacking our 3dm-g converter in various ugly ways I managed to get the
following two surfaces into a .g file:
http://bzflag.bz/~starseeker/extreme_ssi_test.g
I'm not entirely sure they constitute a "fair" set of test surfaces - they
may be too extreme to be regarded as reasonable - but they're the closest
thing I have so far to a general test case for multiple-sub-surface-patch
intersections between general NURBS surfaces. A raytrace indicates the
complex surface structure is there, but unfortunately the shaded display
code is showing flat planes for both surfaces, not just the one that's
supposed to be flat...
Wu, I'm not quite sure what the "correct" command to test these two
surfaces for intersections would be (the only attempt I've made thus far
crashed) but if these turn out to be useful test cases feel free to add
them to the test NURBS geometry in the source tree. (dbconcat will be
useful for that)
