Slicing

Slicing is is one of the most common and useful visualization operations. A 2D dataset is sliced out of the 3D cube and color of each point on the slice corresponds to the magnitude of the data value at that location. Both the slicing and graphic rendering for the slice can be done in one operation using the arbitrary slicer mapper module. This module can also slice in non-orthogonal directions through the dataset.

As with the isosurface example, the dataset is the probability density for finding an electron in a d0 hydrogen orbital. The hydrogen orbital dataset is in "fields/hydrogen.fld" from the default starting directory for the read field module.

Combining Imaging Techniques

This network can easily be combined with the isosurface network to produce a composite visualization. Just grab an isosurface module and connect it into the network.

Seeing Through Isosurfaces

You should take advantage of the geometry viewer's rendering capabilities to help you see the parts of the slice obscured by the isosurface.
Select the isosurface in the geometry viewer and render it as lines.
Select the isosurface in the geometry viewer and use Edit Property to make it transparent. Make certain that the rendering method is set back to Inherit or Gouraud


Cropping Back Isosurfaces

And finally, you can put a crop module right in front of the isosurface module's input connection so that you can peel the isosurface back in orthogonal directions. This is accomplished by the following network.
