Re: path constraint via ICE

Even better :) Le 28/06/2013 12:22, Edy Susanto Lim a écrit : Hi, If we use object as an upvector, then we don't need the Increment Rotation with 2 vectors compound. We can just use 'Direction to Rotation' node.  -tangent as 'Point At'  -the position difference of the upvector object position to the curve position as 'Up Vector' Cheers, edy On Fri, Jun 28, 2013 at 5:58 PM, olivier jeannel <olivier.jean...@noos.fr> wrote: I don't know the official way, but since the tangency will control the rotation on one axis, you just need to add a second Set Rotation that look UP on another axis.

So tangency is controlled in the Increment Rotation node - how would I control the upvector, say with another null? To better understand how it works, how come it is necessary to key the null to zero rot and pos for it to work?   Morten     Den 26. juni 2013 kl. 16:45 skrev Alan Fregtman <alan.fregt...@gmail.com>: http://s3.darkvertex.com/hlinked/ice/ICE_example_kinematics_pathOrCurveUConstraint.png   Maybe something like this? You may need to do more to deal with the upvector better if your curve complexity is intense.   On Wed, Jun 26, 2013 at 10:34 AM, Ponthieux, Joseph G.
