MPEG4 supports interactive 3D scenes (read: games!) via bit-encoded VRML which can include JavaScript. I don't know any software which support this features (even without interactivity), but it is here.
I'd wrote reader for this bit encoding many years ago when company I'd been employed at made custom VRML engine for Samsung featurephones (project was dead on arrival as at this moment smartphones / Android become available and all this lineage of featurephones was killed).
