3D Phantom top, playing with speed
When you receive the animated top, please tear off the film on the matte surface by hand, and then use the mobile phone function to shoot the animation in the sun
Question 1:How the animation is formed: we are generally exposed to 30 or 60 frames per second, that is, switching 30 or 60 different coherent pictures in one second. Then the principle that our gyro can form animation is also in accordance with this law.
Question 2:Why the gyro animation is invisible to the naked eye: because the refresh frame rate of our naked eyes is very high, when the gyro rotates again, we have seen the rotation, and we can't see the freeze frame picture.
Question 3:Why there are sometimes animations and sometimes there are no animations: when you choose 30 frames per second as the shooting format, the gyro must rotate 30 cycles per second /6 (6 pictures) to freeze to the picture, and then generate animation.
Question 4:Why do we have to shoot animation in the sun? The previous question mentioned that animation can only be formed when the freeze frame picture is used. So we should consider a single picture. A picture is composed of aperture, photosensitivity and shutter. When we take a picture of a moving vehicle at night, it will always have the effect of dragging. The reason is that the light is too dark and the shutter is not fast enough. Let's go back and say that when the gyro rotates at a high speed, there must be enough light for us to take a freeze frame picture, so that the mobile phone shutter can automatically meet the high shutter to freeze every frame in rotation
