This article mainly introduces jQuery's methods and code sharing for implementing friendly carousel image effects. For more information, see: [Processing] Here, the image is rotated and processed in a small way: When you click Page 1st in the 5th page status, the image scroll is a slide, instead of from 2-3-4-5 (this kind of multi-scroll, see Dizzy ); The implementation method is as follows: The rest is source code sharing: ------- Css ---------------- The Code is as follows: .

Three or four yuan to Euler angle conversionAs a result of arctan and arcsin, this does not cover all orientations (the range of values for the corners has been met), so atan2 is needed instead of arctan.Iv. use in other coordinate systemsIn other coordinate systems, the above formula should be adjusted according to the definition of the axis. As in Direct3D, the x-axis of the Cartesian coordinate system changes to the z-axis, the y-axis to the x-axis, and the z-axis to the y-axis (regardless of
