Multiple mask display portions to display single image? how?

Attached is the file I’ve been working on.

What I’m trying to figure out is how to get a single image across all of the boxes with the spaces between the boxes compensated for, so that it looks like you’re looking at this image through a set of windows.

So, right now I have a ramp drawn on every box. I need to make it so that only portions of the ramp are drawn on each box that will make the boxes come together to form a complete image of the ramp.

I read in the Kantan posting that this can be accomplished with Crop TOPS but I’m not sure if I’m using it right - or what. The proportions and timing seems off when I try to line everything up that way.

Thanks.

Hi June,
I haven’t looked to far into your toe file but I’ve been doing mapping projects like this for quite some time. This may be easier than you think.

Let me give you a little theory behind how this is done, hopefully this helps. Forget resolution details for now - let’s assume we’re working within a single 1920 x 1080 space coming from a projector.

1. Scale entire space: the 1920 x 1080 space needs to be scaled to contain the height or the width without cropping out any portion of the screens.
2. Calculate image size: Calculate the physical size of your projection area
3. Determine PPI (pixels per inch): Convert physical dimensions from feet to inches to get PPI: 15’ x 12" = 180". ) So, 1080px / 180in = 6 PPI.
4. Calculate screen resolutions: Use the PPI to calculate resolution on the remaining screens. 75.5 in x 6 ppi = 453 pixels

I have some write-ups of how to do this but I figure this may give you a really good idea of how you need to apply the crops to these images to scale them properly.

Let me know if this helps or if it’s a bunch of gibberish.
Thanks.

Hmmmm. I think I understand what you’re getting but - so let’s say it is 570x453.

Where would that go? Under common output resolution? Or - Crop > Pixels (seems to be a range from 0 to 1)

Where would I put the resolution value?

And thanks a bunch!

Ah, you can change your crop values from percentage to pixels here:

We can approach this crop equation with the same formulas presented before with some slight modifications but I’ll write more about that later. Think I’ll start the new year by getting some rest!

Upon closer inspection the workflow I laid out would be doable with an input source routed through a display or projector but the way TD handles image textures adds another layer of “uhhhh, wait a minute. Something isn’t right”.

I haven’t done much mapping through TD yet but I’ll throw together a basic run through of these concepts and add them to the post this evening.

Catch you later.

Brain.

ahhhh. Thanks much. I will play around with it a little more today when I get some time.

I really appreciate you taking the time to help me connect with these concepts.

Cheers.

Hey June,
Check out the attached TOE file, it’s super-basic but I think will help convey the idea. I wish this example were more drawn out with SOPs in a 3D environment but I’m still trying to get my feet under me at the moment.

Admittedly, I am just a toddler in TD and I would still be trying to figure out how to get a button to work properly if it were not for the help of the forum users and the awesome TD staff. However, blending images and working on large scale displays is something I’ve been doing for more time than I wish to remember. My last mapped screen, just before the holiday, was a 31 projector blend on a 30’ x 1,000’ screen.

I still need lots of help but I’m glad to repay it where I can.

Let me know what you think.
