Frustum

Distance Cull
Object that are to far away do not have to be drawn. How far is to far depends on the size of the object, the bigger the object the further it should be seen.

Bounding volume
Wrap the object in a basic primitive such as a sphere or a cube and check if that is visible to the camera. If not it does not have be drawn.
