Description Julien Gouesse 2013-08-08 13:48:11 CEST
The legacy renderer doesn't work with GL3 as you can see below:
Exception in thread "main-FPSAWTAnimator-Timer0" java.lang.RuntimeException: javax.media.opengl.GLException: Not a GL2 implementation
Caused by: javax.media.opengl.GLException: Not a GL2 implementation

        at com.jogamp.opengl.util.awt.TextRenderer.beginRendering(TextRenderer.java:384) 

A contributor provided a patch to improve this renderer but it's not clean, there are some code duplications, it doesn't use our shader utilities, it requires some work:

Of course, this request for enhancement is not in high priority as:
- the new text renderer always supports the programmable pipeline
- several high level engines already have their own mechanisms to display text

@Julien Gouesse: What is the "new text renderer" you speak of? Because I am experiencing this same trouble with "Not a GL2 Implementation" using the class com.jogamp.opengl.util.awt.TextRenderer. Is there another text rendering API I could be using with a GL3 context?

Look at com.jogamp.graph.
