The JS actor does not have any drawing abilities. It can create streams of numbers for animation, that you would feed to a Shapes actor or Lines actor. But can't create polygons directly.

Hi,

The Mac OS patch I recreated from @SherLynn description and indication did not have any unexpected behaviour. @SherLynn would need to provide the file.

I would also love to know if there is a way to modify the anchor point of a shape. 

 Take a look at my answer in this thread, you may find it, and some of the methods I discuss, to be helpful. There's also a Guru Session that Mark did which covers this topic.

You may also find this (as of yet unreleased) motion tracking mini-tutorial I've made to be helpful. (It's bundled with another mini-tutorial on alpha masks, but the motion tracking one will be the one you'll want to look at for this particular topic.)

I am researching around and intuitively I would use OPENNI tracker to track my hand and then hook up the motion to the width and height dimensions but, because I don't have a Kinect compatible with the plugin, before I buy it I would like to know if there is a better way, and even if this method can be successful.

If you do end up going the Kinect and OpenNI route, you will want to check out the OpenNI Tracker Tutorial and download the OpenNI Plugins from our Plugin Page.

to change the anchor point of a shape you can use the FFGLPanSpinZoom actor (spin ctrl x and spin ctrl y). It is not a real anchor point but could simulate it.

This plugin doesn't come with a fresh install of Isadora. You'll need to download the TroikaTronix FFGL plugins from our plugin page and install them if you want to use them. Personally, I use FFGLPanSpinZoom all the time because it's more convenient than using both a Zoomer actor + Panner actor + Spinner actor.

Thanks for the pointers, insight and knowledge. All very helpful and good information to digest.

I downloaded the videos off a list from youtube ( copyright is in place) and the exhibition is part of public facing element on vaccines. The content was existing videos given with consent for the project. I am playing about 12 videos on a loop and all was fine till I realised the designer had put a rounded rectangle in place.....

I take you points re warping. I will follow your guides ref re-using the mask directly and see how I get on. All the scene are set up with a user actor so I can trial it quickly enough.

Again, many thanks for all the advice.

(I used one CI actor, so unfortunately it's Mac-only, you'll also need the TroikaTronix FFGL Plugins: https://troikatronix.com/plugin/tt-ffgl-for-isadora-2-3/)

thanks! I am going through it.
