Simple question about tutorials.

The objects are clipped against the far clipping plane. As I understand it you cannot turn off this clipping, but you can move the plane further away by setting a larger distance when calling glFrustum(), or any other function that sets up the projection matrix (glOrtho(), gluPerspective(), etc).

(Removed gluLookAt() for the reason mentioned below)

(gluLookAt has nothing to do with the far clipping plane.)

Furthermore you won''t have to worry about the far clipping plane because when you have a full 3d scene normally the scene has so many objects that you can''t "see" the far clipping plane.

Thanks for correcting me. I don''t know how that got in there. gluLookAt() is for setting up the view matrix not the projection matrix.

Sorry about that.

to ANSWER your question thou, find THIS line.

gluPerspective(45.0f,(GLfloat)width/(GLfloat)height,0.1f,100.0f);

The 0.1f, 100.0f is the starting point and ending point for how deep we can draw into the screen, if you would like to push that back, change this to 200.0f that will double the depth of how far u can draw
