🎬 Cinema Camera: Shutter Angle, Motion Blur and the Wagon-Wheel Effect (2D)

A spoked wheel and a moving block as a film camera records them. Set the frame rate, the shutter angle, the speed of the object and the speed and spoke count of the wheel, and see the exposure time, the length of the motion blur, the apparent speed and direction of the wheel, and how much contrast the open shutter leaves in the spokes. Exposure and blur, sampled frequency, the shutter as a filter and the stopped wheel are checked with four in-page numerical checks.
