Three drones are flying between forests of trees. Thanks to the
optical-flow (DIS OpenCV) measured on successive images, the
"temporal disparity" reveals the forest of trees (3rd dimension)...

The interest with the forest is that trajectories are curved, in
order to avoid obstacles. It is measured thanks to a projective
transform, and represented with <Ry,Rz,Tx,Tz> thanks to POV-Ray.
The evolution of the drone is shown in front-view with its camera.

Best regards,
