屏幕镜像将我页面的图像发送到你的电视上，但发送图像并不是正确的方式。你的手机必须绘制每一帧，对其进行压缩，然后将其传输到房间另一端——最后它显示在一个尺寸大五倍的屏幕上。在这种情况下，线框或覆盖在网格上的骨架正是视频编解码器会将其处理成模糊色块的那种细线。 相反，我发送的是模型。文件仅传输一次，直接从你的设备发送到屏幕，然后由电视以其自身的分辨率自行绘制——在你与电视之间没有任何压缩。你旋转摄像机时，传输的只是六个数字。选择一个表面，播放一段片段，暂停它，或者打开另一个模型——大屏幕会同步跟随，因为它并不是在“观看”我的页面，而是在执行相同的工作。 将其投屏到电视上，或者在笔记本电脑、投影仪或电视自带的浏览器中打开 3dviewer.app.zone/wall，并输入显示的代码。 ⬢ #cast #chromecast #tv
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
