vtkConeSource::SetDirection not always right
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
If I call cone_source->SetDirection(-1,0,0) the orientation is actually (1,0,0), which is wrong. if I set the direction to (1,0,0) the orientation is correct.
You can use Examples/Tutorial/Step1/Python/Cone.py and add a call to set the direction
Also I've noticed that doing a SetDirection(-1,0.00000000000000001, 0) actually sets it reeeeaaaalllly close to what I want. Make the parameter zero, and the cone does a 180.
