Currently im making a 3d world.... as i posted a week ago in http://forums.inside3d.com/viewtopic.php?t=1401 I now have the majority of my bounding box code sorted however i now need to scale objects... I have managed to do this just fine... however as a side effect of this it seems after scaling even though im only moving any particular object by the exact same speed as previously it appears to move faster if i have scaled the object bigger and slower if i have scaled an object smaller?
Would there be any real reason for this ? the movement speed is a set 0.1 so this is quite strange...
Also when calculating a bounding box after scaling i cannot think of the most sensible way to do this... obviously it cannot simply be scaled by a factor or a percentage because of it being co ordinate based... So does anyone have an idea of what is a good way of scaling the box to the same proportion as i scale each 3d model?
Thanks for the help again guys!

keep scale and offset separate, rather than scaling the offset? _________________ What's a signature?
