You can immediately render realtime global illumination in your 3d scenes if you load them into existing sample application. You can also use your scene loader and adapter.

Recommended approach:

Load your scene into RealtimeLights or Lightmaps sample.

Scheme of application:

RealtimeLights and Lightmaps samples are built on top of purely numerical LightsprintCore, OpenGL 2.0 based LightsprintGL and scene importers in LightsprintIO.

Steps:

Make sure your static scene is suitable for per-vertex lighting, read more in artist's guide.
Convert scene to one of Supported formats, e.g. Collada (.DAE).
Change name of scene in Lightmaps.cpp, so it loads your scene.

Expected time spent:
