Glut depth buffer
Author
I''m using the glut library to create my OpenGL window and set the display mode via
glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGBA | GLUT_DEPTH);
The standard size for the depth buffer is 16 bits, but I need 32 bits precision.
How can I change the depth buffer size?
Thanks in advance
The most simple way would be to change the constant GLUT_DEPTH in glut.h from 16 to 32

You obviously don''t understand why GLUT_DEPTH is set to 16. GLUT_DEPTH is a flag, the fifth bit in an integer, which happens to have the decimal value 16. If you change it to 32, it will represent the sixth bit, which means asking for a stencil buffer (GLUT_STENCIL is defined as 32).
glutInitDisplayString seems to do what you want.

btw many cards dont support 32bit depth
eg with all nvidia cards 24bit is the max
