After playing this Demo, I used HTML5 Canvas to implement similar functions based on its ideas.
So let's talk about the principle of its 360-degree panorama.
1. First, you need to take a photo of the object. The interval is that each photo is rotated for 15 degrees, so 23 photos are required.
2. After preparing the photo, try to select the JPG format and crop it to the appropriate size.
3. Pre-load all photos in JavaScript. The loading accuracy can be displayed with the progress bar.
4. Create/obtain a Canvas object and add the mouse listening event. When the mouse moves left and right, draw different frames in a proper manner. The general principle is like this, simple!
