Hello, subject.

3D in the official website instance is a pseudo 3D effect. There is no need for 3D modeling. You can consider panoramic shooting similar to that of a mobile phone (or professional equipment may be required). The captured image is applied to a cube as a background map. Click to enter another mapping area, which is relatively easy to implement. Consider that threejs, has a relatively close DEMO

has a webgl Chinese website, you can see if it is the effect you want. Use the three.js mentioned upstairs.

all of these sites are generated with one click. If you just need a solution, you can search krpano, which can generate pseudo 3D scenarios through a panorama, but you need to pay for watermarking. There seems to be a cracked version on the Internet.

if you want to learn skills, look upstairs. In addition to the solution of thress js, there is also the method of css3d

for example, the package for css3 columnar sky box such as Taobao creation Festival https://github.com/shrekshrek.

Yes, as said on the first floor, first use professional equipment to take global photos or videos and then similarly change its angle to display different areas

the krpano, roaming I used before, of course, you can also do it yourself with three.js.
