<html><div style='background-color:'><DIV>Hi, All</DIV>
<DIV> </DIV>
<DIV>Sorry for asking this question again. I followed instructions from Bill
and Don, and I used the following code (partial list) to draw some texts.</DIV>
<DIV> </DIV>
<DIV>RealType shape = new RealType("shape");<BR>ScalarMap shape_map = new
ScalarMap(shape, Display.Shape);<BR>display.addMap(shape_map);</DIV>
<DIV> </DIV>
<DIV>RealTupleType coord_type = new
RealTupleType(longitude,latitude,elevation,shape);</DIV>
<DIV> </DIV>
<DIV> double[] start = {0.0, 0.0, 0.0};<BR> double[] base =
{0.3, 0.0, 0.0}; <BR> double[] up = {0.0, 0.3,
0.0};<BR> boolean center =
false;<BR> <BR> PlotText pt = new PlotText();</DIV>
<DIV> </DIV>
<DIV> VisADLineArray shape1 = pt.render_label("My text is
here", start, base, up, center);</DIV>
<DIV>//shape2</DIV>
<DIV>//shape3</DIV>
<DIV> VisADGeometryArray[] shapes = new VisADGeometryArray[]
{shape1,shape2,shape3};</DIV>
<DIV> ShapeControl shape_control = (ShapeControl)
shape_map.getControl();<BR> shape_control.setScale(0.2f);<BR> shape_control.setShapeSet(new
Integer1DSet(3));<BR> shape_control.setShapes(shapes);</DIV>
<DIV> </DIV>
<DIV>I also used the following code to specify the location for the text and
add the shapes to display:</DIV>
<DIV> </DIV>
<DIV>RealTuple coord_tuple = new RealTuple(coord_type, new double[]
{samp2[0][0],samp2[1][0],fResult2[0],0});</DIV>
<DIV>DataReferenceImpl ref_coord_tuple = new
DataReferenceImpl("ref_coord_tuple");<BR>ref_coord_tuple.setData(coord_tuple);<BR>display.addReference(ref_coord_tuple,streetColor);</DIV>
<DIV> </DIV>
<DIV>The code worked for me. The text is displayed at the given location (in
this case, samp2[0][0],samp2[1][0],fResult2[0])as we can see from Test 45 and
Test 69, i.e., the text is dsiplayed parallel to x-axis and I can
read it as output from any System.out.println.</DIV>
<DIV> </DIV>
<DIV>Now, I want to display the text with any specific angles to x, y
and z axis. for example, I want to display text with 50 degrees to x-axis,
100 degrees to y-axis, and 260 degrees to z-axis. I do not know how to set
start, base and up in this case. </DIV>
<DIV> </DIV>
<DIV>Thanks a lot.</DIV>
