    Stacking 3D objects and maintain correct perspective

      I have searched and searched but cannot find any useful conversation about best practices in stacking 3D objects.

       

      Here is the scenario, I have a marketing photo of a single device but I need to synthesize stacking of multiple copies. The problem is view point and perspective change with each copy of device.

       

      Example:

      stacking 3D objects.png

       

      Notice that the copy [top image] doesn't align on left-side and back-right side. What tricks can be used to manipulate the copied image in order to simulate proper perspective? I have tried playing with the 'perspective' function but it doesn't allow the corrections required.

       

      I have attached a .psd file of above images, if you wish to experiment. Note: this is a random image I found for demo purposes only.

       

      Thank you for your advice.

       

      Grrr.... Adobe Forum doesn't seem to allow .psd attachments! Seriously?

          Would be fantastic if PS supported persistent projection baking in its 3D part, would it not? Would make this a walk in the park. Otehrwise you will have to muddle through. A good place to start would be to separate the faces so they can be warped and skewed separately, then clone them as needed. Ultimately you will only need one top face - more or less - anyway.

            "separate the faces"

             

            That is what I am already doing but I didn't want to taint the conversation with what I though might not be the best method.

             

            What I am doing is separating the face, the top, and the side (3 separate layers) and skew the heck out of the back to pieces, and finally, a little bit of free transform to make everything mostly fit together. I real pain... especially manually masking the face plate (because there is not enough contrast to use the magnetic lasso).

             

            I guess we need to go here and make a feature request (not sure it helps)? https://www.adobe.com/cfusion/mmform/index.cfm?name=wishform&product=12

             

            Wondering if there are any other ideas (besides getting new photos)?
