"nested" projectors? (mapping and repositioning problem)

  • Hi everyone,

    My co-workers and I have gotten in the habit of using alpha channels and the horizontal/vertical/scaling of projectors to create compositions within a screen. 
    We're just getting started with Isadora 2, and the mapping features are really exciting, but it seems like once we set a mapping for the projector, there's no way to reposition or scale movies/pictures within that mapping. We're so used to moving the projector itself around that we're kind of stumped.
    One idea that I had was the possibility of nesting projectors, so that the final projector handles the mapping, and projectors are fed into that projector for positioning and scaling. Is this possible?
    The Stage Settings provide exactly what I'm asking for, *except* that we have more than one setup in our current show, and it seems that there is no way to have more than one Stage Setting at a time.
    I appreciate any advice, even if it's to rethink our workflow.
    Thanks in advance!

  • There's an FFGL plugin called FRParameters that provides all of those adjustments before a projector. http://www.1210visuals.net/index.php?option=com_content&view=article&id=48:frparameters&catid=34:freeframe&Itemid=58 I think it'll probably do what you're trying to do?

  • you can publish each parameter in map outsie it,  "published" parameter became a input value of your projector. When you are in to mapper just right click on what you need to be published

  • Dear @danieljackson,

    @Maximortal is right. But to clarify what he said:
    Each slice in the mapper has parameters that can be "published" as an input to the projector. For example:
    1) Add a new Movie Player and Projector.
    2) Double click the Projector to create a new IzzyMap
    3) You'll see there is a default "Rectangle" slice
    4) Go to the output and resize this size, making it smaller
    5) Right click the rectangle. From the menu choose "Publish Rectangle 1 : Offset X" Repeat this for "Offset Y." (As you can see, there are many other options, including the transparency, the rotation, etc.)
    6) Close the Izzy Map editor
    7) You'll see that the Projector has two new inputs: "Rectangle 1 : Offset X" and "Rectangle 1 : Offset Y." You can change these inputs to move the slice around horizontally and vertically.
    If you create a second slice, you can publish it's "Offset X" and "Offset Y" and move it independently.
    Maybe this allows you to do what you need to do. If not, let us know and we can help you further.
    Best Wishes,
