Category: Miscellaneous Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Nobody/Anonymous (nobody) Assigned to: Nobody/Anonymous (nobody) Summary: make vertices/object move along paths Initial Comment: Synfig is great fun to do animations in, but there are is one thing that has been bugging me and, to the best of my internet search skills, does not seem to have been implemented/described anywhere. Basically, I would like to be able to draw a bline with N vertices and have a shape move along that bline (the whole shape or individual vertices). Currently the only way I have found to do what I want is to draw a bline, and then move a shape along that line manually at fairly small intervals (very frustrating). Example: A triangle that should move along a sine curve always pointing in the direction it is going to move next. In that case I would like to be able to draw the triangle and the sine curve (or other bline) and say move the centre of the triangle along the bline and rotate it according to the shape of the bline. I have no idea how you would implement that, but it is a feature readily available in most 3D animation programs. Aternatively/in addition, it would be great to be able to change/edit the "movement path" (I have no idea what it really is called) in the window in the time-line dialog (the one selectd by the icon with the squiggly line next to the keyframe window), i.e. adding vertices or editing the tangents so that the interpolation between keyframes is changed. I hope I didn't just miss either of these features. Synfig is great (a big pat on the shoulder of the developers and the people producing the tutorials) but the documentation is quite sketchy at times so finding what is possible and how to do it is far from straight forward. ---------------------------------------------------------------------- >Comment By: dooglus (dooglus) Date: 2007-09-24 00:12 Message: Logged In: YES user_id=1546005 Originator: NO I implemented this in svn r745. See http://wiki.synfig.com/Following_a_BLine for a tutorial and http://wiki.synfig.com/Convert#BLine_Tangent http://wiki.synfig.com/Convert#BLine_Vector for documentation. ---------------------------------------------------------------------- Comment By: dooglus (dooglus) Date: 2007-09-18 18:30 Message: Logged In: YES user_id=1546005 Originator: NO I found that it is already possible to get an object to follow a single bline, but not a general outline. I uploaded an example to YouTube: http://www.youtube.com/watch?v=wJ7C-FcxAy0 The sif file is http://dooglus.rincevent.net/synfig/follow-bline.sifz and the .avi movie file is http://dooglus.rincevent.net/synfig/follow-bline.avi I still intend to make it possible to do the same for general outlines (lists of blines). I had to fix a few bugs in Synfig to get this to work, so it probably won't work in any of the released versions. The fixes will be in subversion in an hour or so, and will be in the next release. ---------------------------------------------------------------------- Comment By: dooglus (dooglus) Date: 2007-09-18 02:45 Message: Logged In: YES user_id=1546005 Originator: NO Interesting suggestion. I'll have a go at implementing something like that soon. I'll post more here as and when I've got anything. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=757419&aid=1781903&group_id=144022 ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
