For my project I need to discretize curvature in a UV grid.
Doing so in Rhino took 180+ seconds, in PythonOCC it takes less than 2.
Over a 100* fold speedup...
What can I say... thanks Thomas!

tA = time.time()
u_grid, v_grid = numpy.arange(0.0, 0.1, 0.0002), numpy.arange(0.0,
0.1, 0.0002)
for u in u_grid.tolist():
for v in v_grid.tolist():
curvature.SetParameters(u,v)
s=curvature.GaussianCurvature()
is_locally_spheric = curvature.IsUmbilic()
#tan_u, tan_v = curvature.TangentU(), curvature.TangentV()
_mean, _min, _max = curvature.MeanCurvature(),
curvature.MinCurvature(), curvature.MaxCurvature()
tB = time.time()
print 'It took', tB-tA, 'to sample n_samples',
u_grid.shape[0]*v_grid.shape[0], ' a N*N grid',
u_grid.shape[0] ,'*', v_grid.shape[0]
tA = time.time()
for u in u_grid.tolist():
for v in v_grid.tolist():
pass
tB = time.time()
print 'Just looping ( python overhead, NON optimal ) takes ', tB-tA
