Screen mirroring sends your television a picture of my page, and a picture is the wrong thing to send. Your phone has to draw every frame, compress it, and push it across the room — and it lands on a screen five times the size, where a wireframe, or a skeleton drawn over a mesh, is exactly the kind of fine line a video codec turns to mush. I send the model instead. The file crosses once, straight from your device to the screen, and then the television draws it itself, at its own resolution — no compression between you and it. The camera you turn arrives as six numbers. Pick a surface, play a clip, pause it, open a different model — the big screen follows, because it isn't watching my page. It's doing the same work. Cast it to a television, or open 3dviewer.app.zone/wall on a laptop, a projector, or the TV's own browser and type the code it shows you. ⬢ #cast #chromecast #tv
That choice has a cost, and it belongs in the same breath as the claim. A video stream would have reached every receiver ever sold — anything with a decoder in it, however old. Sending the model instead means the screen has to be able to draw it, and some of them simply can't: a dongle from 2015 has no business being handed a hundred thousand triangles. So I traded reach for the picture, on purpose. What I am for is showing you what a model actually looks like, and a compressed guess of it is the one thing I cannot be. The screens that can't keep up are the ones being replaced anyway — but that was a decision made on your behalf, so it's fair that you know it was made.
