What really is real time? // New Users 1  |   Order by default Post by TylerZambori // May 25, 2008, 6:48am TylerZambori Total Posts: 100 It seems like this term is bandied about a lot, and some softwares (not TS) like to claim they have it, then one finds out they don't have really real real time. I'm told that it all depends on how heavy the scene is - the key is whether the scene is "heavy" or "light," and that all 3d software stops being real-time as scenes get heavier. sheesh. I dunno about that. But I would think that a software like TS is "real-time" no matter how heavy or light the scene, right? To me waht it really means is that you can see what you are working on without needing to do even a preview render, but apparently some people have other definitions. thanks, Tyler Post by Jack Edwards // May 25, 2008, 9:30am Jack Edwards Total Posts: 4062 I guess originally "real-time" was defined as rendering fast enough to display "in real-time" -- 24 frames per second or faster. Now-a-days, I think the definition is more a way of distinguishing between hardware rendered from the video card, vs. software rendered from a rendering engine like VRay or Lightworks. Though even there the line is being blurred by render engines like Gelato that use the video hardware to assist in calculating the render. So I think the it still comes back to the time-based definition. Realtime is a rendering process that happens fast enough that you have immediate interactive feedback. Video games for example....

I'd also say that when you render from workspace using directx, that isn't real time even though displaying it is the same as it isn't happening in such a way that you are getting 25-30fps...mind you, as hardware power increases I'd say that will change - CPU and disk performance here i'd imagine. The fact that you can output a frame every 3-4 seconds is a massive speed boost.
