Here are our first exeperiments of creating a 3d engine to integrate our work; Using [https://github.com/nama-gatsuo/ofxDeferredShading] as a basis to render shadows, lights, SSAO and some post effects the first results were encouraging.

Still some problems arose quickly. My first test was to load a complex scene as a obj file and using subsets of that obj file to set camera positions and orientation. That went quite well but was quite heavy performance-wise. As loading such large objects with all the lighting calculations put our integrated GPU on its knees.

So we started working on a modular solution for the moment using 4 obj files with subsets.

For example here is a group of 9 objects each being a subset of interior.obj. (each color indicating a different object). On each load, a random element is chosen from the list and displayed.
