Syntax:
vacuum { vector_lo, vector_hi }
Where is - vector_lo lower corner, - vector_hi higher corner.
Same as box primitive.
vector_lo, vector_hi is like a bound.
These two values directly goes to BBox field of OBJECT struct.
Vacuum primitive is only important for developers of POVRay.
It is useful for speed testing and bug finding.
For users vacuum is useless!.
