HI.

I would like to find an example of a panorama with cubemap in practice a cube in which I can move as in a classic panorama ,possibly in webgl , but it would also be fine in opengl.

the modification that I would like to be able to do is to dynamically change one or more textures of the cube, shouldn't it be impossible or not?

thank you all

First hit I get is https://learnopengl.com/Advanced-OpenGL/Cubemaps​

Given that it's a site for learning OpenGL, there is an example there with a cubemap and everything gets explained, so you can change everything and more as you desire.
