Any suggestions on a good, efficient algorithm for testing for the visibility of an object?

1. bounding sphere round each object.
2. hierarchy of bounding spheres to group objects.
3. test spheres hierarchically against a cone representing the frustum.

That should be enough to cull away the vast majority of what isn''t visible.
