[x3d-public] Fwd: Meshes as images and image generation

[Joseph D Williams]

➢ Indeed, can mesh animation be represented as an image or images?

Yes, we have significant practical proofs of that happening in anywhere everywhere realtime anytime yourtime, all the time, relatively. The details are not sketchy, the capture of any instant may be thought of as a keyframe, which, In the case of animation of the subject mesh, can interact with other keyframes depending upon the author intent to produce model behavior between key defined instances. 

Creating and animating a mesh can be simple, just move the mesh points and look at the the 2D on your screen. Once yo have this then probly the best way to hide how you did it would be to covert to a 2D, like make a video. That wil make it fard for anyone to figure out much about how the thing was actually created except that it must have been a lot of work.

For starters, can STL be converted to image(s) and recovered?

The idea would be to generate (mesh) images, then translate them to STL.

I realize several pictures can be translated to 3D meshes, and one can render the meshes.   I am more concerned about the fidelity of the geometry.

The idea would be to use the image(s) as an alternate encoding of the STL.  One probably couldn’t view the image and 3D model and recognize them as each other.  The images would encode the tuples of the STL at a minimum.

Should we discuss adding time as a coordinate to normals and vertices in STL for animation?  4D printing?

I read recently on this list i think that meshes can be represented in an “image” format.   I am wondering if the current crop of image generation tools, like DALL-E/2, imagen, parti, MidJourney, and stable diffusion could be used to generate meshes in that image format.

Thanks!
