This code works well for an ostensibly-static world in Unity, to avoid doing raycasts or anything similar.
Might need some adjustment to the specifics of how it currently works in Unity or your scene

// Firefox 3.6 is awful slow on both methods, but the first one is a tiny bit faster than the second one (on winXP 32, AMD x2 2.2GHz 4GB ram, it does 522ms vs. 534ms).
// Firefox 4.0 is some sort of improvement, but is still godawful slow. 340ms and 350ms, respectively. I guess Tamarin does not help much on this.
// Chrome Canary Build flies on both methods, and the second one is almost 2x faster - 45ms vs. 27ms
