Within this tutorial we learnt how to produce a 3d scene from a 2d image using the photoshop technique of vanishing point.
The concept uses a grid system as shown in the screenshots and converts it into a readable file in after effects that can then be repositioned to become planes with materials (planar images) and thus create a perspective view of a scene.
This shows the initial photoshop technique using the filter vanishing point where planes are mapped using a grid system. each grid exports as an image for 3d use.
The set up within After effects. Numerous scale and position tweeks are necessary before the image starts to come to life.
Further evidence of the manipulation within after effects. Here you can see how the floor has been taken from the orginal photo and mapped on to a regular rectangular plane.

The final composition showing the corridor set up and the camera positioning allowing a realistic perspective using a 35mm lens and a path through the elements.
