      Plus some stuff, the cloud choice is made for you. I've been using OnShape for browser-based CAD for 3d printing design, and so far it's been simple enough that it hasn't choked. But I expect it to choke if I try anything too complex. So I have to upgrade laptop anyway.

      Oh, web app kind of "cloud". These actually run in your browser, so what you need is just good hardware. I define cloud as computing happening elsewhere. Also, why use a web apps for models? There are dozens of better options.

      I want to have the option for all 3: native apps (including on a VM in a guest OS), browser-based cloud-apps, and true cloud apps. I think some of these browser based apps offload heavier compute to the backend and only do low-latency bits locally, like renders.

      Uh, kinda doubt that. Renders are the heaviest part, everything else is just trivial geometry. AI stuff is what tend to be offloaded.

      I guess if it's not super interactive and you can predict a bit and do some parts of it offline. Like track the slew of the camera and predictively process and pipe parts of a scene that are coming into view.

      Uh, no. For a CAD thingy calculations only happen when you alter stuff, and these are trivial unless you are doing large scale CSG stuff or run physics sims. The relatively non-trivial part is rendering, including the what's in the scene magic. And you aren't making movies there.

      So for consumer level apps, photo-realistic 3d with offscreen action like maybe in multiplayer games, is where some predictive cloud processing would help, like google's cloud gaming thing

      Predictive cloud processing? Are you sure this isn't an xkcd #451 moment? But broadly speaking yes, you need a stream-a-movie level connection and a fairly dedicated machine on the other end to do tasks like video editing, CAD, photoshopping, gaming and so on fully off your hands

      Like, there is a send-voice-to-cloud,-get-text kind of offloading, and then there is game-runs-remotely,-send-video-back kind of offloading. Or take-picture,-send-to-cloud,-get-filtered-back kind of offload. Different requirements.

      Take a game of chess. You can have the browser render the board, and a cloud computer do the thinking. Whatever latency, tiny bandwidth connection. Or you can have a remote computer do the board rendering and thinking. Low latency, movie-grade bandwidth, and a GPU on remote end.

      predictive cloud processing is literally how one startup described what they were trying to do for this kind of stuff :D latency is partly a hard roundtrip floor time constant, but also partly a "when do you know you'll need the result of this computation and where?" thing
