Hi.
I can use the glutDisplayFunc() to rotate the stuffs I draw. But this doesn’t work when I want to scale the viewport to see more stuffs. Do I need to use glScale() to scale the stuffs or change the fovy of the gluPerspective()?
Thanks.
What do you mean see more stuffs?
Can’t you just draw more?
Hi,
I can draw more, but I just can’t see them. At the present, I just can’t understand well what the Viewport is. So, I want to the form to display everything I drawed.
He probably is getting clipped by the near and far plane. If you are using a perspective frustum, then set znear to 0.1 and zfar to 2000.
If you are in ortho projection, then I guess -1000 and 1000.
