Hello, I have problems using OpenGL with my 2011 Macbook Pro 13".
My system has the following configuration:
Mac OSX 10.8.2 Mountain Lion
Sandy Bridge @ 2,3Ghz with HD3000 graphic
I've tryed different releases of JOGL and Gluegen, downloading the automatic builds here:
http://jogamp.org/deployment/autobuilds/master/I run the attached code using Eclipse with the jogl-all.jar and gluegen-rt.jar both imported and the result (see "Crecked" image) is that spheres appear "cracked". This seems connected with the light, becouse drawing flat-color spheres without light gives no problems.
I've tryed installing Eclipse on my Windows 7 BootCamp partition and the result this time is perfect (see "Correct" image).
I can't find a solution.
