Graphics Card Inspection

[kalinwilson]

We have an Eclipse RCP based application that is deployed via Java web start. We've run into situations where users download the app to machines with graphics cards that aren't suitable or optimal for worldwind. Is there support within worldwind/jogl for reporting on the graphics capabilities of the host machine so that we can warn if capabilities are missing?

I didn't find anything in the forum on this when I searched.

Thanks,
Kalin

Have a look at WorldWindHackApps.ShowExtensions.java

    public void display(javax.media.opengl.GLAutoDrawable glAutoDrawable)
    {
        javax.media.opengl.GL gl = javax.media.opengl.GLContext.getCurrent().getGL();

        boolean fbo = gl.isExtensionAvailable("GL_EXT_framebuffer_object");
        String es = gl.glGetString(javax.media.opengl.GL.GL_EXTENSIONS);
        javax.media.opengl.glu.GLU glu = new javax.media.opengl.glu.GLU();
        String eus = glu.gluGetString(javax.media.opengl.glu.GLU.GLU_EXTENSIONS);
//        Object pexts = glAutoDrawable.getGL().getPlatformGLExtensions();

        String[] esa = es.split(" ");
        String[] eusa = eus.split(" ");
        java.util.Arrays.sort(esa);
        java.util.Arrays.sort(eusa);
        for (String s : esa)
        {
            System.out.println(s);
        }
        for (String s : eusa)
        {
            System.out.println(s);
        }
    }

Thanks for the pointer!
