---|
| 3 | # |
---|
| 4 | # This widget visualizes scalar/vector fields on 3D meshes. |
---|
| 5 | # It is normally used in the ResultViewer to show results from the |
---|
| 6 | # run of a Rappture tool. Use the "add" and "delete" methods to |
---|
| 7 | # control the dataobjs showing on the plot. |
