vtkSelectVisiblePoints not getting some valid points as visible
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
When using vtkSelectVisiblePoints, some points are marked as invisible when they should be visible.
at about line 161 diff = fabs(z-dx); if( diff <= this->Tolerance ) ....
now lets say that z = .6 and dx = .4 and Tolerance = .001. That point would be invisible even though if it were drawn, it would be visible.
Should probably be something like if( dx < (z + this->Tolerance) )
now lets say z = .6 and dx = .4 and Tolerance = .001 then my point would be marked as visible, because if it were drawn, it would be visible.
