Hi. I need to make similar project: https://campusalbano.se/view/all and I ask if is possible in babylonjs have a multiple hotspots on a 3d model with mesh clicking and appears a window with informations and change views camera?
The short answer is yes. Here is one possibile method to change camera views https://www.babylonjs-playground.com/#DXE1CV#1 from this topic where alternatives are also considered and can be adapted to your use.
You do not have to set up a full app to ask questions you can try out your ideas in a simplified playground. For example two or three boxes for buildings, spheres for hotspots to click and move to and show a GUI textblock.
I try it now.
Thank you very much for your help
