Can the 3D stage Orientation Actor follow a path?

OK, 

I'm trying to make an animation that evokes those 1st person views from a rollercoaster and I'm curious about adding in dynamics which respond to real world input.

This only feels like it would be possible if I can track the camera (read 3d stage orientation) to a path so that it can follow the surface of a 3d model that I import (in this case an implied track), but I'm not really sure where to start on this one.

So is there any way to track a camera to a path in isadora, or should I make do with a prerendered animation instead?

It might be possible to do this with a spline path. Although I haven’t tried this myself with the ‘3D Stage Orientation’ module, I have a workflow for 3D paths implemented for 3D objects and particles etc. in Isadora.

I start by making the shape with requisite number of points in a 3D software and export. I then open the 3D file in MeshLab and export as a JSON file. In Isadora the ‘JSON Parser’ (it might require multiple) is then configured to read out the point data (x,y,z). This is done simply enough with a ‘Pulse Generator’ and a wrapped ‘Counter’. The streams of x,y,z would then each be fed to a ‘Limit-Scale Value’ before linking to the ‘3D Stage Orientation’.

The other thing to look at is the ‘3D Ropes’ as this has a follow path built into the module. You can limit the parameters to one rope and control curve etc. the actor has option to reveal coordinate xyz outputs that travel along the rope as a 3D path.
