Re: Modify surf output (axes, scaling)

Thanks :) until then, fred's tip with the Compute Normals filter does a pretty decent job. Still, I have some questions about this filter and some more general, small problems with mayavi2.

About the original topic: how do I apply the filter via shell? enthought.mayavi.filters.poly_data_normals.Instance(s) seems to create an instance of the filter, but it dooesn't show up in the scene explorer.

And on another note: Can I somehow change the behavior of the camera/mouse interaction? I'd like the system to rorate only about two axes, the vertical and the horizontal one. In other words, the axis which is separately activated when I press ctrl should be disabled when moving the viewport with the mouse normally. Is that possible?

Also, how can I move a glyph-plot relative to the origin of the scene (for example, from enthought.mayavi.mlab import quiver3d;from numpy import array;quiver3d(*array(range(6))) )? Moving surf-plots works by choosig Array2DSource->Data->Origin. Is there a equivalent way to do this via shell or explorer for a quiver3d plot?

Thanks again, cheers

Thomas

OK, Thomas, that won't solve your issue in the short term, but I just
improved the surf and mesh functions to address this. In the upcoming
release of mayavi, you'll get the same nice smooth surfaces.
