Hi Desiree,
Text2D utility implement this by Texture2D. So if the texture
size is bigger than that support by graphics card. The text
may not show correctly or is truncated. It is up to the
underlying driver to handle it. In this case when font
size change from 560->660 it just went pass the maximum
texture limit so font did not show correctly. When the
font size is too large, Java3D need to allocate a bug
chuck of memory for the texture so it is possible to
run out of memory. You can use
java -Xmx128m -Xms128m Test
to increase the heap size of java.
The method
text2D.setRectangleScaleFactor(2);
text2D.setString("new 2D Text");
should work in v1.2.1 release.
However
text2D.setRectangleScaleFactor(2);
will not change the scale factor if it set
after scene graph live. (workaround is to
call setString() after it). Bug 4431725
is filed for this.
Thanks for your bug report.
