Features

Click the cell under "C" column to bring up the color dialog to change the color of the mesh.
Press Grab switch to select the surface mesh directly. This will show up the grab handles for all the meshes.
Add clipping plane by pressing "X". A widget will appear showing the position and orientation of the clipping plane.
Use Outline parameter to bring out the internal structure within the data. The "Transparency" parameter affects the level of transparency of the surface. The outline will always be opaque.
Use the explode command to separate out difference meshes from each other. Normalized coordinates are used.
A label is attached to the mesh. A line is drawn from label text box to the mesh to which it is attached to.
Save a keyframe with meshes in original positions and then another one with their positions moved either via explode or individually.
