I made a user actor that allows the user to feather the edges of any Izzymap shape.

This is great for projection-mapping on organic shapes, when you don't want a sharp edge.

In order for the actor to work you need to setup a virtual stage first. Please read the comments inside of the user actor for instructions.

The technique is based on @DusX 's technique described in this thread: https://community.troikatronix...

There is some weirdness. When I add user input actors for intensity and active, they sometimes default to "0" or "1" no matter what I do. Also, the order that the user input boxes appear in the scene editor seems to be pretty arbitrary.

@woland

thanks  for explaining ! and thanks so much for the feature request ! 

@michel Great, thanks just tried it out! Thank you for the fast reply!

@woland thank you!

@Kathmandale 

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.

although that could be convenient to have the rotation parameter shown so as for the resolution when we move a point.

 Yes, I already added that as well. :)

@mark Ah that makes sense, and gets it all in one place so easier to layout.  

Thanks, 

Mark

I thought It was because of my projector definition

 What is your projector definition? The higher the resolution the better (obviously) but also understand that the larger the image you're trying to project on a surface, the more visible the individual pixels will be. 

@fred

All excellent points. I can see how this would be a very valuable addition to IzzyMap. Thank you for taking the time to give us feedback :)

I have a case where I want to use a user actor for mapping a lot of small pieces, but I want to use the same mapping for an alpha layer, but the pieces in the two need to have different blend modes. It would be great if the projector blend mode had some other options, like when the mapper was engaged the blend modes still worked, so they could be additive, transparent opaque OR mapper. and when the mapper was used and transparent was selected it would set all the mapper pieces to transparent. If it was set back to mapper then it would use the blend setting of the individual pieces. I think there are other options for doing this, but a way of having the smae mapping with different blend modes for using alpha layers with different projectors into the mapper would be cool.

BTW would be great to see/monitor datas of the mapping points ( ex: you need geometrical form and you need feedback to accomplish it perfectly)`

+ @mark could it be possible to publish all points of a composite with a single clic? 

@dillthekraut thank you very much !!

Best,

Thank you Michel for the fast answer.

This seems to work for what I need.

On Mac you have these options:

 Sorry! Today all day behind Windows/Mac makes me confuse, so, control-click publish points and command-click adding points.  Thanks

 No worries, I only knew that because I went and checked to verify. It's a lot to keep straight in one's head, especially cross-platform.

That buttermilk suggestion could saved me a lot of money..... Thanks for the tip! I will try in the future.

@woland perfect, That will do the job nicely. thanks.

Although I still don't know why the "complex shape" tool behaves differently for me in the input window than the output window.

it's one of those gaps in understanding that I feel will come back to bite me at a later date when I need to mask something a bit more detailed. 

Oh well, I'm on track for now at least. 

thanks everyone, You've given me some paths to start investigating.

I'll either come back with a bunch more questions or i'll let you know what I settle on.

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.
