The ContourWidget handles mappings to IsoContour in both the 2-D case and the 3-D case. The "contours" checkbox will turn contours on and off in both 2-D and 3-D. The JSlider is for selecting an iso-level in 3-D (it has no effect in the 2-D case). The "labels", "dashed lines", "interval", "base", and range select controls are all for controlling iso-contours in the 2-D case only. They do not have any effect in the 3-D case. DisplayTest 1 demos the ContourWidget in 3-D. DisplayTest 5 demos the ContourWidget in 2-D. It turns out to be a rather complicated issue for the ContourWidget to detect whether a given display is in 2-D or 3-D, so it just displays all of its controls all the time, even though some of them are not necessary in certain cases. -Curtis -- Curtis Rueden <curtis@xxxxxxxxxxxxx>, (608) 262-7288 VisAD home page: http://www.ssec.wisc.edu/~billh/visad.html
