First of all, I love that new jit.anim.path object, it's a great object to make the transition between After Effect and Max and since my main interest in interactive cinema, it's just what I need !

A few questions. See patch below for illustration.

1. To animate the position of a GL object, I use the append message. Is that the best way ?

2. Once I have a path, how can i playback the path ? I found that sending stop, time x then start works well but then how do I stop the animation if I simply want to play from time2 to time3. I thought that next would do that job but that doesn't seems to work...

jit-anim-path

hi nnimar, glad you are finding the anim.path object useful.

unfortunately, there is no built-in way to tell the object to play back from one keyframe to another, although that sounds like a nice feature, and you can consider the request registered.

however, it's quite simple to do this yourself, by querying the @time attribute (gettime).

i've modified your patch to demonstrate this.

let me know if anything is unclear.


What would be great with this tool is to have the same options than After Effect's motion paths and key framing system (or better). I would like to have access to the various keyframe interpolations such as easy ease, easy in, easy out. I have seen the intermode attribute but linear and spline change both the motion path and the keyframe.

I have also tried to take the data from jit.anim.path using zl ecils to process the numbers before sending them to gl.gridshape but if they are not connected, there are no output from jit.anim.path.

the jit.anim.path has a @drawto attribute that allows it to automatically sync it's animation to the render context draw-swap. when you connect an anim.path to any jit.gl object, that attribute is set automatically.

if you want to set it manually (eg when an anim.path is not directly connected to a jit.gl object) you simply need to provide the @drawto attribute explicitly to the anim.path object.

Picking up where this thread left off. Is there a way to specify the handle locations and/or do we have access to parameterization for splines?

hello there, do you know what is the "rate" property relates to the time unit in real world? for example, how do I do if I want to force the object to finish its path in 1 minute, thanks!
