hi,
while converting the documentation chapter on scene inspection i found
that the inline help example of (bb/bb-intersect?) does not work.
(clear)
(define a (with-state
(build-sphere 10 10)))
(define b (with-state
(translate (vector 2 0 0))
(build-sphere 10 10)))
(every-frame
(begin
(with-primitive b
(translate (vector (* -0.1 (sin (time))) 0 0)))
(with-primitive a
(when (bb/bb-intersect? b 0)
(colour (rndvec))))))
it looks like the bounding box is not transformed, and they are checked
for inclusion not for intersection.
