[ANSWERED] Position Data --> Data Visualization

emullis

Hi there.
I'm working with the Rokoko Smartsuit Pro and would like to display the x,y,z data for particular joints from the Rokoko Studio Live Watcher. That is, I'd like the audience to just see the streaming data of, say, the x coordinate of the left elbow. Is there a way to capture and display this?

Thank you for any assistance!

Text Formatter and Text Draw are likely the actors you are looking for.

If you right-click the Rokoko Studio Live Watcher and select the top option from the contextual menu ("Show Actor Help in Browser") there's a list of joint names. Rokoko doesn't have a tracker on the elbow, so you need to pick 'left-upper-arm', 'left-lower-arm', or do some math yourself to figure out the likely position of the elbow.

These joint names can be put into the 'point sel' input of the Skeleton Decoder actor to make it show data for just that joint (or just the selected joints if you provide a list).

This is wonderful. Thank you.

That said, Izzy is now crashing every time that I start steaming data from Rokoko Studio in. It works fine if I don't use the Rokoko Studio watcher or if I don't stream the data. If data is streaming and I add a watcher into a patch; crash. If I have a watcher already in and then turn on streaming in Studio; crash.

Here's what I'm running:

- Izzy 4.1.1
- Rokoko Studio 2.6.1 (most recent version)
- MacBook Pro - M2 Pro - Tahoe 26.3.1

Please let me know next steps.

Questions for you:

Can you try in Isadora 4.1.3 (the most recent public version)?
Can you try with the legacy version of Rokoko Studio?
Are you working with a Rokoko SmartSuit Pro II, or the first version of the Rokoko SmartSuit Pro?
