I am not sure why your code would hang. There are three approaches to doing this: 1. Do much as you are doing, but extend VisADCanvasJ3D and put you draw call in its renderField() method (followed by super.renderField()). This is necessary to synchronize with Java3D rendering. 2. Put your text in VisAD objects and plot the way that Test45.java and Test69.java do in visad/examples. Note that this locates text in data space rather than screen space and so may not be what you want. 3. Use the new J3DGraphics2D class that is part of Java3D, and is described in the version 1.2 documentation. This is probably the best approach for you. Good luck, Bill ---------------------------------------------------------- Bill Hibbard, SSEC, 1225 W.
