when I use "print hits” I read the value 0.50000000016 for both min_depth, max_depth.
For example, when I call “print min_depth, max_depth, names” l’output is:
0.50000000016 0.50000000016 [object_X’s name]
0.50000000016 0.50000000016 [object_Y’s name]
If I use GLdouble(min_depth or max_depth), I read 0.5000000001641532
I read always 0.50000000016 except when I draw objects very near. At that moment I read values like 0.49…, 0.48, …. etc. and min_depth != max_depth
It seems that Selection works only in range [0.2,0.5] where 0.2 is forced by gluPerspective(45, 1.0*width/height, 0.2, 2.0)
If you want I can send you my code but I will do it only if you are agree.
Sorry if I write you no at sourceforge.net. It seems that I am not able to create a new account

Oggetto: Re: [PyOpenGL-Users] Need help about Picking
Unfortunately, I can't immediately detect any problems with this code.
-The name stack is, by default, only 64 large. There's no advantage to having a 1024-length selection buffer.
-What happens if you use "print hits"? Is it all zeroes?
