For my graduation project in design university I'm working with the technique of vacuum forming. My goal is to be able to physically print an image onto a sheet of plastics and then form this sheet of plastic over a mold (for instance a face). Like described in this video: https://www.youtube.com/watch?v=kKHb1hBS7bY&index=57&list=PLhQgkDdtdogQNrsdQWNkaNwtS8ROL_PdF&t=3s
The problem is that the plastic sheet does not equally deform everywhere so the image that im using needs to be pre-distorted according to the deformation of the plastic. My plan to solve this problem is to first print a grid on a sheet of plastic and form this over the mold so I have an idea of how the plastic is deforming. I could then 3D scan this formed piece of plastic with the grid on top. But then my question is: How do I figure out how to deform my original texture so it fits the face perfectly when I vacuum form it? Thanks a lot in advance!
I made a more comprehensible overview of the steps I made to obtain the deformed image. See added picture.
Step 1: I drew a grid on a piece of plastic. I vacuum formed this plastic sheet over the clock so now I now the deformation of the sheet of plastic
Step 2: I 3D scan the sheet with the grid
Step 3: I remodel the geometry of the clock and overlap the faces with the deformed squares of the scan
Step 4: I 3D scan the original clock
Step 5: I bake the textures from the scan of the original clock on the model I made in step 3
Does anyone now have an idea how I can take the newly baked texture and deform it so it matches the undeformed grid I drew on the plastic sheet?
