trouble with gl*List()

OpenGL Development JOGL Development
#1

Hi all, thanks in advance for the help.

I’m trying to make calls to glCallList and glNewList by passing an integer variable as my parameter.

That is, I have a static Integer id, and I call using gl.glCallList(id) and also gl.glNewList(id, GL.GL_COMPILE).

However, I get a big GL exception when I try this. The only way I’ve found of not running into an error is if I pass an actual integer as a parameter (something like glCallList(5)).

Exception in thread "AWT-EventQueue-0" javax.media.opengl.GLException: glGetError() returned the following error codes after a call to glNewList(): GL_INVALID_VALUE 
	at javax.media.opengl.DebugGL.checkGLGetError(DebugGL.java:12715)
	at javax.media.opengl.DebugGL.glNewList(DebugGL.java:6151)
	at ObjMaker.drawObject(ObjMaker.java:23)
	at Node.apply(Node.java:232)
	at Node.apply(Node.java:237)
	at SceneGraph.draw(SceneGraph.java:99)
	at Main.display(Main.java:52)

Can variables be passed to these methods?

UPDATE: Ah…0 isn’t allowed. That was the problem. Thanks anyway ::slight_smile:

You should acquire the ids for your lists via glGenLists.
