hi,
what there already is for translation? If not, how hard would it be
to add something like (lock-camera-target (vector n n n)) so that
wherever the camera is, it's always pointed at that spot or object?
i think this should not be very difficult. as far as i know, lock-camera
works by getting the global transformation matrix of the object, inverts
it and multiplies the camera matrix with it.
3) Is there a quick way to translate the axis of rotation on a
primitive so that it does that orbit-effect instead of rotating in
place?
you can achive this by switching the order of translate and rotate. are
you thinking about something like this?
(clear)
(define p (build-cube))
(every-frame
(with-primitive p
(identity)
(rotate (vector 0 (* 90 (time)) 0))
(translate #(3 0 0))))
