In Response To: Re: Holy crap, you're a genius! (Bry) : Well you're 10 years late in raising an objection with it. : Point is that its been part of Halo since the beginning, so you'll just have : to accept it. : I'm no trekkie, but a hologram that is able to interact with physical objects
Indeed it is. The name may be a different one, but the way Trek holodecks work is they have holographic emitters and forcefield projectors lining the walls of the chamber. To simulate a boulder, forcefields are projected along all axes in the room and converge on a point where the simulated rock will be. The forcefields can be fine tuned to great precision. Imagine that the rock is like a wireframe mesh in a 3D program. The forcefields project a 'surface' where all the mesh points would be. This makes it so the user can touch the simulated rock and they encounter a forcefield at its periphery and can't push past it, thereby making the holographic construct seem real; physical. The holo emitters contain imaging as well and can project a texture over the forcefield making the simulation look photo-realistic. The Trek holodecks also use the matter-energy conversion technology of the transporter to recreate actual items too, so things like water, snow, paper, etc. are often real items. Halo's "Hard Light" probably operates on a similar principle...manipulated precision-tuned forcefields. The forcefields can either be tuned to permit matter to pass through or not depending on field polarization. Polarization would also allow hard light to either permit electromagnetic radiation through, creating either an opaque surface or a window. No, I haven't given this ANY prior thought. ;)
