General TouchDesigner Discussion

Hi,
I am learning about the edge blend through the tutalial named “Introduction to touchdesigner.pdf”,but I can’t find the container named edgeBlend which was mention in the pdf.
I’m using the version of touchdesigner is 088 .
Could you tell me how can I find the container of edgeBlend .And there is other new way to blend serval projectors ?

Thanks very much for any help.

Hey,

there are several approaches to this. In the Palette you can find 2 components which can help with this:
Under Tools you can find the projectorBlend Component which can blend multiple projectors that are aligned in a grid.

Another component which allows for blending is camSchnappr. This is used in case you are projection mapping onto a physical structure which you have the model for. As you would calibrate the camera for multiple projectors, camSchnappr will output a blend mask which you can apply onto each output. There is more information on camSchnappr here:
derivative.ca/wiki088/index. … mSchnapper

Also currently if you are running TouchDesigner with a Pro License, you will be able to find the Scalable Displays TOP. More info here: derivative.ca/wiki088/index. … e_Displays

The edgeBlend is in the palette. (maybe the name has changed since I wrote the tutorial). To get to palette you can either use Alt + L, or in the top menu, go to dialogues, and you will see Palette in there. Then you go to tools and you can find it.

Hi Snaut,
thanks a lot for your help.I have found it in the palette,which named projectorBlend.And try to use it last weekend.I will try the CamSchnapper this week.By the way ,May I know which is better between the CamSchnapper and the Scalable Displays TOP? Becase I haven’t bought the Pro License yet.

The Scalable solution is super powerful but you’'ll need a $$$ licence from Scalable Displays.

Does anyone mind outlining the pros and cons of using Scalable Display vs Vioso? Looking into using either for a large semi permanent multi-projector setup that needs some auto-calibration as well as significant blending.

I was leaning towards Vioso for a few reasons, cost being one of them, but would love to hear what people think.

Thanks!
