I only released parts of the hallway and the VisionSpace room. It is nothing but a demo project, but this can show you what is possible with very little amount of work. I finished the project in a few days after accurately measuring out the lab and taking pictures for reference and textures. Some of the texturing is very primitive and only rudimentary lighting via a lightmap is implemented. Every 3D artist would most likely run away screaming, but it's not art but rather the kind of environment I could use to simulate a navigation training or cognitive training for problem solving. I could give this to our Health & Safety Department so they can have people simulate fire / earthquake / tsunami alarms etc. It's not pretty, but useful....and very accurate. If the floorplan is accurate, this model is to scale to the closest millimeter.
You can walk with WASD or the arrow keys on your keyboard and head rotation works via moving your mouse. Right-click on the player window to select fullscreen if you like. A decent graphics card is recommended. If it doesn't run on your machine, I can send it to you as an executable or a video recording would be an option as well.
I'd appreciate feedback.
Video tutorials about the creation of this walkthrough will follow.
You can find the demo here.
