Hi Olver,
You are probably using a DisplayImplJ2D or a DisplayImplJ3D
with a TwoDDisplayRendererJ3D. In both cases it wll try to
display lines and points over filled triangles. Text without
a font (or with a Hershey font) uses lines, text with a font
uses triangles (and hence go behind the lines of your FlatField).
The easiest approach is to use a Hershey font.
Another apporach is possible if you are using a DisplayImplJ3D
with a TwoDDisplayRendererJ3D. It is to not use the
TwoDDisplayRendererJ3D, but instead use:
GraphicsModeControl mode = display.getGraphicsModeControl();
mode.setProjectionPolicy(DisplayImplJ3D.PARALLEL_PROJECTION);
You may also want to call MouseHelper.setFunctionMap() to
disable rotation (see an example of this function in
visad/examples/Test00.java).
By not using TwoDDisplayRendererJ3D, you can use ConstantMaps
to ZAxis to explicitly place your Text and FlatField in depth
to control what's over what.
Good luck,
Bill
