Realization of interactive virtual environment on wordpress site

I would like to create a virtual environment for a virtual art gallery (virtual showroom). The created environment will have to be integrated on our website [login to view URL] , perhaps adding to the main menu the words "Enter The Gallery ". The first image that will have to appear will be the image of the front of an art gallery, made with renderings, with structure and characteristics to be decided. Then clicking on the word ENTER (perhaps located on the entrance door or nearby) you will have to access the virtual space. The virtual space must be well cared for, adapted to an art gallery. We can decide the details together. On the walls there will be exhibited our works of art for sale and the user must have the possibility to move in the virtual environments and be able to approach and admire the works of art at best. It would be useful to be able to chat online (for example to ask for information) and to be able to buy the works directly from the platform.
