I have been given a project to create a 3D virtual tour of our school, and then it will be display on a big touchscreen monitor at the lobby where school visitors can utilize it to find classrooms and places.
My questions is what kind of software do I need, aside from Sketchup, in order to accomplish my project?
Currently, I am about half way through finishing the campus. I found out that I need to find something for rendering my model to make it look nicer. I also saw some people suggested Unity 3D or 3D Max to create virtual tour, but it will take some learning curve.
I am hoping to get some open source or freeware (if possible) which can easily import models from Sketchup to create a virtual in a few steps. And also the end product should be touchscreen friendly with arrow buttons (and interactive icons).
Thank you in advanced and I will be looking forward to your kind suggestions.
