A question about tracking

Thank you — it's nice to know they were appreciated!

These are the best copies I could find on archive.org (Wayback Machine):

Part 1:

Give them some time to load - archive.org can be a little slow.

I've restored the download links to the demo projects, but you'll need to remove the portion of the links that starts with:

HTH

I reconstituted the articles on one of my sites:

https://sight-creations.com/mysteries-of-oscs-part-one/

You should only need the one link to navigate the three parts and all the download links should work without editing. If they don't — let me know!

Hi

In Motion, there are two options.

1: Track Points Behavior. I think you may already be referring to 'point tracking' but if not, there are some resources here

Track Points controls in Motion – Apple Support (AU)

The best resource I have ever known that explains how to apply the track points behavior to control the points of a shape or a line is an article by Fox Mahoney called 'The Mysteries of OSC explained'. The website that hosted this article is not running anymore, but hopefully Fox will catch this thread and help you here with a link

The article has been used as the basis for many tutorials out there on youtube..but the read about it and learn first hand is the best way to understand everything in context.

The article is related to creating onscreen controls, but in the methods shown, you also have the answer to your question.

2: Line replicators - you can attached the start and end points of a line replicator to objects

In this case, the line displayed is made with a replicator, and the start and end points are linked to the positions of the shapes - as one shape is animated randomly and the other stays still ..you get the result you described.

You can use the line replicators for path networks. To do this with track points behavior is not as easy or versatile.

However, if you are thinking of a template that you can create for FCP, your options are restricted to the user of 3rd party trackers which can be published to FCP, and give more tracking functions than the tracker in Motion and in FCP.

Hi Fox

Thank you so much :)
