I didn't have a chance to look all over through the JOGL docs, i'm mostly coding at the help of samples.

the initi() setup is like below, my 3D obj have a very strong deformation while rotating. it looks like the deformation is because "bigger nearer and smaller faraway", i tried a few combinaions of "DEPTH" (i have no idea what's depth func, just trying -_-!!) but does have no luck. what do i miss?

UPDATE:  my code is modified from this:https://github.com/ILDAR1976/JoglObjLoader-master, i replaced the original obj with mine, the obj still deformed, but i didn't look that much with the "plane obj".

i have an exe ObjViewer, and that does not deform at all.

And another question, how do i make the light just shine like sun, no shader, do not change reflections while rotating?

                gl.glBlendFunc(GL2.GL_SRC_ALPHA, GL2.GL_ONE_MINUS_SRC_ALPHA);
                gl.glEnable(GL2.GL_BLEND);
