How to render 3D anamorphic movie on curved screen? (or fake 3D image)

Hi!
I’d like to show the anamorphic motion graphic( or i think it can be called fake 3d art) on the curved glass screen. it should include the front, side, ceiling as well.
Is it possible to render 3d anamorphic panorama with a third perspective view in one single movie?

Here is the reference that I want to make.


youtube clip is here here

As you can see those images, those methods are already rendered as calculated distortion for giving 3d depth. Even it is only effective from the specific point to see, I want to test it as a mockup though.

I got information that a specification of this curved screen that 7,840 by 1,952 pixels of resolution. (also 80m width and 20m tall it is, but for making mockup, it’s not necessary.)

here is an interesting idea that similar to my aim.

But I have no idea to implement that with python or more coding.

Plz, give me any idea!
Thanks!

I think @magdesign know how to project on that screen.

You don’t need to create the screen. Using fSpy addon you can get the correct perspective for the camera, model a cube and render your object and animation. After you will have to composite, color grade and some masks. If your animation go outside the box you will have to create a shadow catcher and maybe a few rotoscopes if have people or objects in front of it.

Here is the scene: display.blend (959.1 KB)

Thank you for your answer!
That addon looks so cool!
However, my aim is slightly different :disappointed_relieved:.
That is not composite on still image, i want to render a single flat image for showing on the real curved screen directly.

The below image is what i what to get from rendering.
is there any way to get it?

Thank you for your introducing him!

It’s called texture extraction or projection painting, it will extract an image disconsidering the camera perspective. Here’s a tutorial:

If you want to do the oposite, you need to reverse the other file I sent.

Thank you for answering!!
That’s quite a good way to get texture! maybe I can use it when I need to modify my 3D scanning project to fix the losing part!
I’m so sorry that it also has a gap with my desire.
Composited still image is not my goal.
like in my last reply, the result of what I want is one flat single image for a curved screen. That image is to show 3d feeling to the audience in reality. To be elaborate, it will be short animation of the internal space of the box. So while rendering the animation, I think it needs to manipulate that intentional distortion on the result of rendering.

Hi
I am very new to blender, actually I was searching for the same thing how to create such content on the screen. How did you manage to get the flattened output shown above? If any one knows the method to render out the distorted projection in the final resolution of the display.

you need to model your stage/object in realscale, then define the “best point of view” and render from there with a large lens 80-100mm.
its quite tricky, but doable.
anamorphic projections will never work from all view points… hope that helps.

Thank you for your advice. how can I get the flat distorted rendered output in the specified resolution?

you need a mapping tool like ofxPiMapper or similar…

Thanks, will try it out.

Hi guys, I just signed up!
I have to make a 10 second animation for a double 3D led screen, where a character seems to “come out” from the led screen. I don’t know how to set it all up. I can’t find tutorials on the net.
I would like to understand: how do I render the scene to give the feeling I need?
I have read the conversation above but need some more help.
Can you kindly help me please?
Thanks.

Nobody? :frowning:
I hope someone can reply.

Thank You.

Yeah, I can help you. Just a bit busy at the moment. I’ll get back to you.
