Hello all,
One quick question
I have a proven program that works with stl import. However, when i try to
import this file [1] i get the following error
FATAL /build/yade-KKgSmd/yade-1.20.0/pkg/common/Facet.cpp:26 postLoad: Facet
has coincident vertices 0 (0 0 0) and 1 (0 0 0)!
FATAL /build/yade-KKgSmd/yade-1.20.0/pkg/common/Facet.cpp:26 postLoad: Facet
has coincident vertices 0 (0 0 0) and 1 (0 0 0)!
FATAL /build/yade-KKgSmd/yade-1.20.0/pkg/common/Facet.cpp:26 postLoad: Facet
has coincident vertices 2 (0 0 0) and 0 (0 0 0)!
What i dont understand is why. The same file without one tiny shape covering 2
holes passes just fine.
The code i use to import the stl is the following
facets = ymport.stl(name)
rod1 = O.bodies.append(facets)
# converts facets to gts (see the other question)
s = gts.Surface()
for facet in facets:
vs = [facet.state.pos + facet.state.ori*v for v in
facet.shape.vertices]
vs = [gts.Vertex(v[0],v[1],v[2]) for v in vs]
es = [gts.Edge(vs[i],vs[j]) for i,j in ((0,1),(1,2),(2,0))]
f = gts.Face(es[0],es[1],es[2])
s.add(f)
print s.is_closed()
threshold = 1e-3
s.cleanup(threshold)
print s.is_closed()
assert s.is_closed()
# use gts to filter spheres
pred = inGtsSurface(s)
print "r = ", r
I really appreciate any suggestions
