Almost all of the world's image sources are planar, which is almost impossible if the planar image source is to be displayed on a three-dimensional LED spherical screen and left untreated. Fortunately, the ball is round, any one individual audience can not see every corner of the LED screen at the same time, he can only see a small part of the surface of the ball only. This is also related to the diameter of the ball screen. If the diameter of the ball screen is sufficiently large, its effective focus is probably only about one-sixth of the surface area of the ball (due to the angle of view), of which sixty-fifths are not visible Or not their attention, because the five-fifths are respectively on the front and back of the ball, on the left, on the right, right above, just below. In this way, you can use the playback method:
1). Six different image sources are played in six different areas of the sphere.
2). Play three different image sources in three areas of the sphere (left rear, top right, front bottom).
3). Play two image sources in two areas (front right rear, top left bottom). Of course, you can like watermelon LED spherical screen as a flat image source to play on the entire sphere.
