Hi - can anyone recommend a good framework/IDE for designing indoor spaces (e.g. shopping mall) and then adding moving objects to this VR space. I need
a) A good GUI for designing the building (e.g. entering floor dimensions, wall structure types, stairs etc). I would be working from building architecture floor plans.
b) An API that would allow me to add moving objects into this VR building and watch them moving around in realtime.
I've had a look at some of the related questions on SO, but the answers tend to link to game oriented solutions and I've not seen one that has a good usable GUI for building the VR 'shopping mall' artifacts.
