Hi Renaud,
The original bug is reproducible by
examples/PickTest/IntersectTest
and is fixed in v1.3 release so you should
not able to reproduce this using the test.
Although the stack trace is the same,
the problem that you encounter is different.
As you can see from the utility source code
of PickIntersection,it did throws
RuntimeException at
double[] getInterpWeights()
in
case 3: // triangle
if (!interpTriangle(0, 1, 2, coordinates, pt)) {
throw new RuntimeException ("Interp point outside triangle");
}
break;
which I think is
pointCoordinatesVW;
not initialize properly before
pickIntersection.getPointCoordinates();
invoke.
Please send us a complete test case to take a look.
Thanks.
