Hi Eugene, Display. Shape is now implemented. Note that case 47 includes a box, as in your original request, that has different colors, locations and sizes according to values of RealTypes mapped to color DisplayRealTypes, spatial DisplayRealTypes, and Display. Here are some words from Section 4.7 of the Developers Guide about Shape. The DisplayRealType Display.
Shape can be a very powerful tool for building complex displays.
When RealTypes are mapped to Display. Shape, their values are quantized according to the Set argument to ShapeControl.setShapeSet and the resulting indices are used to look up VisADGeometryArray shapes. These are located according to any RealTypes mapped to spatial DisplayRealTypes, scaled according to any RealType mapped to Display. ShapeScale, and for those VisADGeometryArrays that do not include colors values, colored according to any RealTypes mapped to color DisplayRealTypes. Multiple RealTypes may be mapped to Display.
