Hi Scott,
Your program set point antialiasing to true
even though only surface is drawn
pointAttrib.setPointAntialiasingEnable( true );
APP_SURFACE.setPointAttributes( pointAttrib );
In v1.3 beta2 we have bug which classify the
surface as transparency and render in the
transparency queue with depth buffer disable
in this case. (bug 4678932 is filed for this)
Comment out the line
pointAttributes.setPointAntialiasingEnable( true );
will make the program works. However if you
program did use point and line array with
antialiasing on, this is correct behavior.
The reason why it works in D3D version because
point/line antialiaising is not support, so
the checking immediately put those geometry in
the opaque queue to render.
When the object is picked with highlight,
the program set both transparency
highlightAppearance.setTransparencyAttributes(ta)
and CULL_NONE
So the backface and frontface will render in random
order with z buffer turn off. This is expected
behavior and not a bug.
Thanks for your bug report.
