Consider a long fabric - say 150 cm x 800 cm. One end (A) is mounted 600 cm above the floor and the other end (B) is mounted 200 cm above floor and 400 cm horisontally away from (A). At (A) the fabric is mounted on a rod 150 cm long. At (B) all fabric are gathered as tight as possible.
Is it possible to find a way to show such an element i Capture 2018?
