Caused by: javax.media.opengl.GLException: Not a GL3 implementation

Question

I am getting a "Not a GL3 implementation exception" in the method init when it tries to do the assignment.

void init(GLAutoDrawable glad){
GL3 gl3 = glad.getGL().getGL3();

}

I downloaded the jogamp-all-platforms. I am using Eclispe IDE and configured the build path by making a new user library. The new user library has all the jars of the jogamp-all-platforms in it. I looked at similar questions but it is not that helpful.

Answer 1

You should read this document. In your case, glad.getGL() is probably a GL4bc instance or a GL2 instance. It depends on the GLProfile instance you use in your code.

Answer 2

The easiest way I've found to debug these kinds of things is to get a GLProfile and print it as a string -- this way, you can easily see whether or not your system actually supports a specific version. You can do this with something like:

GLProfile glp = GLProfile.get(GLProfile.GL3);
final GLCapabilitiesImmutable glcaps = (GLCapabilitiesImmutable) new GLCapabilities(glp);
final GLCapabilities tGLCapabilities = new GLCapabilities(glp);

System.out.println("System Capabilities:" + glcaps.toString());
System.out.println("Profile Details: " + glp.toString());
System.out.println("Is GL3 Supported?: " + glp.isGL3());
