Cannot generate a manufacturable .obj model

[toddwprice]

• On macOS, I installed julia with brew install julia.
• I modified the cat image to be black and white first, and save as a PNG:
  
• I added the Images package to my global environment. Then ran julia create_mesh.jl cat_posing.png. It generates the following .obj model, as seen imported into MeshMixer:
  
• Zipped and added here for reference:
  cat_posing.png.obj.zip

Unless I'm missing something, this model doesn't appear to have the desired features that would produce a "magic window". I'd love to help but thought I'd first see if anyone else has had success generating a model successfully.

@toddwprice the surface details are very small so depending on the display settings of your modelling software, you may not be able to see them. If I open the file you linked in your above comment in Fusion 360, I can see the image of the cat because of the way Fusion displays mesh details. So I think you were successful in running the code and you got the expected result, it's just not easy to see in MeshMixer.

@timtomch thanks for the reply. How did you open the .obj file in Fusion 360 though? When I upload it and open it, it appears to be an empty mesh:
