Summary0002651: SNL: Streamlines wrong for uniform rectilinear data
DescriptionWhile making a toy vector field with rectilinear data, I noticed that when I made a streamline it was nothing close to what I expected. Attached is a pvs file that sets up a 20^3 image with a simple vector field that spins around the X axis. You would expect a streamline to form a circle around the X axis, but what you get is a streamline that seems to go in completely the wrong direction.

The problem only seems to happen in rectilinear data. If you convert to an unstructured grid (with Clean to Grid), the streamline appears as expected.

The problem was in ComputeStructuredCoordinates - the voxel location being returned was not correct when the lower extent wass not (0,0,0). Problem has been corrected.
