How do I know the location of hotspots in the obj (3d model)?

There are multiple ways to find them out.

You can
- move around in 3D space using WASD keys with the depthmap navigator (examples: https://krpano.com/examples/?depthmap) and get your view.tx, view.ty, view.tz locations
- use tools like https://krpano.com/plugins/userplugins/toolbox/#top or https://krpano.com/plugins/userplugins/addhotspot/#top to get the locations
- manual trial and error

If you are interested in putting annotations on 3D models, I would recommend (selfish self promotion): https://krisoft.gumroad.com/l/buzwy Then you dont need to know the locations, you just drag and drop the annotations in 3D space. The location of the annotations are displayed as well if you need them :)

How do I know the location of hotspots in the obj (3d model)?

I want to set the hotspot in the correct location like Matterport.

How do I put the x,y,z position in the hotspot?

You can import the model into blender and use my PanoCamAdder Addon to get the values (location; rotation; scale; width; height) for the hotspots.
