In the 3D Contour Editor [21], the user makes fine adjustments in computer-estimated curves, using their neighbours in space or time as a guide to help distinguish fact from artefact. Figure 2 shows a snapshot of this environment, in which the editing tool is editing a control point.
The stylus interacts with the stack of MRI slices. Each slice is a 2D MRI density map, texture-mapped over a polygon. In each stack, there is always a 'working slice' or slice of interest, in which the contour editing takes place. Editing primitives include move or delete points, change of slice, play-back control, magnification, etc. . .
