virtual void draw ( )

overridevirtual

Override this method to draw your own node.

The following GL states will be enabled by default:

• glEnableClientState(GL_VERTEX_ARRAY);
• glEnableClientState(GL_COLOR_ARRAY);
• glEnableClientState(GL_TEXTURE_COORD_ARRAY);
• glEnable(GL_TEXTURE_2D); AND YOU SHOULD NOT DISABLE THEM AFTER DRAWING YOUR NODE But if you enable any other GL state, you should disable it after drawing your node.

Reimplemented from Node.
