What kind of restaurant are you opening? I have my own furniture business and I use an augmented reality platform so that buyers can see the furniture in their own space and decide if it suits their style. You should add
AR integration to your restaurant interior design process. It’s a platform from Vizbl, which I also use. You can see how each piece will look in the space, avoiding unnecessary deliveries and reducing costs. There is also a very interesting article on this topic, it also talks about what you are interested in: customization and multiplacement of several 3D models at once. Read it, maybe it will be useful to you.
