Provides advanced camera features, including full camera movements and animations.
Usage
It's already built-in in @antv/g
, with the lite version to use the following way:
import '@antv/g-lite';
import '@antv/g-camera-api';
The camera can then be retrieved from the canvas to perform the camera action.
const camera = canvas.getCamera();
camera.pan(100, 20);
API
Action
The camera's three axes in the camera coordinate system are uvn, and the camera action is actually moving and rotating along these three axes.

Animation
We can record the current position and viewpoint of the camera and save it as a Landmark, and then when the camera parameters change, we can switch to any of the previously saved Landmark at any time, with a smooth switching animation, similar to the camera pendulum on a real set, also called flyTo in some applications.
