TextRenderer rendering faults

Hi,

I'm using the TextRenderer class to display some labels on various 3D objects.

I'm using com.jogamp.opengl.util.awt.TextRenderer and call it like this:

//... rotate to align to screen space ...
textRenderer.begin3DRendering();
textRenderer.draw3D(text, ...);
textRenderer.end3DRendering();
textRenderer.flush(); // doesn't really make a difference.

However, when I'm drawing many objects (100+), the text renderer sometimes swap characters arbitrarily. It seems like it does some wrong look-ups from the character map. The problem persists when changing "setUseVertexArrays(...);"

Could I be doing anything wrong? Any ideas for a work-around or solution to this?

Regards, Mikael.

(This is on Windows Vista 32bit, Geforce 570GTX, and using the 11/04-2013 auto-aggregated builds.)

Hi

I already succeeded in drawing hundreds of labels with this text renderer. Please provide a unit test.

Yes, I understand it is difficult to help without having a unit test case - the reason I ask this way, is because these things are not always easy to reproduce.

So I was hoping someone had a suggestion before I started working on a test case - it is quite likely that the error is on my side.

I understand your position. When I started using the text renderer, I complained about its high memory footprint and it was a bit difficult to exhibit this behaviour with existing test cases. I had to fix it by myself. I have no suggestion of workaround as I have never experienced what you described.
