>Subject: [JAVA3D] Bug/problem with OrientedShape3D with Offscreen rendering
>To: [EMAIL PROTECTED]
>
>We're using an off screen buffer and have several simple shapes identified but
>text names using Text3D. In order to keep the text in the correct orientation
>we've used OrientedShape3D.
>
>This has worked fine up until the point we actually used the Off screen buffer.
>The text itself doesn't seem to scale with the other shapes.
>
>Below is a simple example, simply enter a scaling factor in the dialog
>(0.something to about 10 should work fine) and view the result. The Sphere
>scales but the Text does not.
>
>There is a SHOW_BUG boolean you can switch in the code to demonstrate what we
>expect to happen.
>
>Comments would be welcome.
