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.
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.
Hi, so trying out the suggestions - it would be great to have a dynamic control of the contour of the tiles. - May be here the 3D Quad Distort object has the highest flexibility. But I am not sure how to tweak all the parameters of "3D Quad Distort" to shape on-the-fly. So it needs a few more experiments.
