if youve watched my production animation - you may have realised the flaw in that the square based pyramid DOES look like it rotating but seems to get thinner and wider on every 45 turn (one face). i was going over this and realised it looks like this because it was "mapped" out on an isometric square (isometric has no perspective as it is used mainly for design/instructional images). Last night i was working on sorting this out and cracked it! i wand a 5:5:5 cm pyramid and all i needed to do was work out the distance away it would look for 5 cm... geddit?
look at the posted images and you should understand...
The image above is the final base that i'd need to work on to get a regular pyramid and therefor correctly fluid animation.
i was amazed at the processes gone into these simple motions - it made me realize how tricky it must be for real animators.. they probably have formulae to work with regarding these things - the perspective thing about the marked CM points getting closer was just something my mum taught me but it seems pretty mathematical really.
