Adobe Photoshop Extended can import and manipulate 3D models in several popular formats, including 3D Studio (.3ds) and Universal 3D (.u3d). You can manipulate these 3D models in Photoshop Extended and then save one or more frames as PSD files that you then import into After Effects.
When you use the Vanishing Point feature in Photoshop Extended, you can then use the File > Export For After Effects CS3 (.vpe) command to save the results as a collection of PNG files—one for each plane—and a .vpe file that describes the geometry of the scene. You can then import the .vpe file into After Effects. After Effects uses the information in the .vpe file to recreate the scene as a composition containing a camera layer and one perspective-corrected 3D layer for each PNG file.
The camera is on the negative z axis, at (x,y)=(0,0). The point of interest for the camera is in the center of the composition. The camera zoom is set according to the field of view in the Vanishing Point scene.
The 3D layers for the planes in the scene have a parent layer with its anchor point at the center of the composition, so the whole scene can be transformed together.
Vanishing Point exchange only works well for images that have square pixels in Photoshop.
The effects in the 3D category in Illustrator—Extrude & Bevel, Revolve, and Rotate—give a three-dimensional appearance to any vector graphic object, including text and drawings. If you want to add depth to your vector art and text, consider creating it in Illustrator, using the 3D effects, and then importing the results into After Effects.
