  1. Multiple 3D layers in one Photoshop document

  2. Photoshop document with one 3D layer • A Photoshop document with one 3D layer

  3. Duplicating the original 3D layer • Duplicating the original 3D layer

  4. Duplicating the original 3D layer • Let's accept the name suggested for the new layer

  5. A document with two 3D layers • Now the layers panel shows we have two layers • although we can see only one cone in the document • this is because both layers are identical

  6. Some key parts of a 3D layer • Each 3D layer has many different parts • For now, however, it is important to note that every 3D layer has its own • 3D object • or, as we will see later, a set of 3D objects • camera • ground plane

  7. A document with two 3D layers • Turn on the 3D panel

  8. A document with two 3D layers • Since the upper layer is selected in the layers panel, • the 3D panel contains information about this layer

  9. A document with two 3D layers • Click on the ground plane toggle in the 3D panel to ...

  10. A document with two 3D layers • ... to turn on the ground plane for the upper layer

  11. A document with two 3D layers • In the layers panel, select the lower layer • In the 3D panel, toggle the ground plane switch for the lower layer to ...

  12. A document with two 3D layers • ... turn on the ground plane for the lower layer • Both ground planes are now turned on • But we can see only one ground plane in the Photoshop document because the two layers are identical

  13. Let's see what happens when ... • Let's see what happens when • in a document with more than one 3D layer • we move the camera for one layer

  14. Moving one camera in a document with two 3D layers • Select the camera tool set • Since the lower layer is selected, the camera tools will manipulate the camera for the lower layer

  15. Moving one camera in a document with two 3D layers • When we alter the camera for the lower layer • we see both ground planes

  16. Moving one camera in a document with two 3D layers • The Photoshop document shows the images seen in both cameras • Each camera is looking at its own cone and its own ground plane • Both ground planes are in the same place in XYZ space • Both cones are still in the same place in XYZ space • because we have not moved either 3D object • But two cameras see different images • because we have moved one camera and not the other

  17. Moving one camera in a document with two 3D layers • If we turned off both ground planes, • the contents of the Photoshop document would make it appear that one cone has moved • But neither cone has moved

  18. Moving one camera in a document with two 3D layers • The situation is exactly the same as if, • instead of having two cones • we had just one cone • and photographed it with two cameras • from two different angles • and then superimposed both photographs

  19. Exercise • Tackle Exercise 20
