When cesium renders by frame, what is the size of each frame

When cesium renders by frame, what is the size of each frame, and how to determine? How do 3Dtiles work together with frames? What is the relationship between tile size and frame size?

HI @ahzdj

I’m not exactly sure what you mean by frame size. The size of the framebuffer is determined by the size of the <canvas> element the Viewer/CesiumWidget is instantiated in.

At runtime, you can access the Scene.canvas property to access its height and width, as shown in this Sandcastle.

Hope this helps,
Sam.

Thank you for your reply.
I mean, a frame is a unit of data transmission, and its size is different, such as 417 bytes or 64 bytes. So I want to know how many bytes cesium uses to render 3D Tile data by frame. And I want to know what controls this value, such as the size of 3D Tile data tiles or the default value. If the tiles control this value, how many frames can a tile generate?
I look forward to your reply.
