This shot was created as the title sequence for a 30 second short video.
First, an image was taken of an empty classroom all of the chairs removed. Then, the classroom tables were recreated in 3D as colliders for the desk rigid body simulation. The CG desks themselves were custom-textured and then dropped over the classroom.
Finally, retro-style framing and grain was added to the CG desks and classroom in order to unite them together.
