OpenGL depth issues

[DeadEli]

I am trying to write a basic 3D game with OpenGL and when I make the objects far enough back they disappear. What I want is to have the objects look smaller when they get further back. How can I get this to work?

Adjust the znear/zfar planes.
Look at glFrustrum()

I tried adding this:
glFrustum(1.0, 1.0, 1.0, 1.0, 5, 100);
but it seemed to do nothing. What am I doing wrong?

glFrustum is so last millenium.

I found this quite helpful:

Or, more specific to your problem:

It uses OpenGL 2.0 so some deprecated functionality is used, but that's rather small-ish things (like using gl_FragColor and stuff like that).

Don't see how it's last millenium as it's the same thing as doing glm::perspective. Simply different parameters, one which requires more knowledge than the other.

Glut is so last millenium, a lot of newer options are available, as well as open sourced.
