I want to reset the camera's starting position and disable the left and right buttons

[smart4654154]

At present, the default starting position of the camera is (3, 3, 3), and users can move it freely.
Now I want to set the default camera starting position at (a, b, c), and users can move it freely. Simultaneously I want to disable the left and right key functions of the keyboard(Stop rotation function). May I ask where to modify it? Thank you very much.

Hello!

The initial camera pose is set here:

viser/src/viser/client/src/App.tsx

Line 291 in e43b4ac

camera={{ position: [-3.0, 3.0, -3.0], near: 0.05 }}

You can also change it from Python via something like:

server = viser.ViserServer()

@server.on_client_connect
def _(client: viser.ClientHandle) -> None:
    client.camera.position = (1., 1., 1.)

For the left/right keys, the code is here:

viser/src/viser/client/src/CameraControls.tsx

Lines 158 to 189 in e43b4ac

	const leftKey = new holdEvent.KeyboardKeyHold("ArrowLeft", 20);
	const rightKey = new holdEvent.KeyboardKeyHold("ArrowRight", 20);
	const upKey = new holdEvent.KeyboardKeyHold("ArrowUp", 20);
	const downKey = new holdEvent.KeyboardKeyHold("ArrowDown", 20);
	leftKey.addEventListener("holding", (event) => {
	cameraControls.rotate(
	-0.05 * THREE.MathUtils.DEG2RAD * event?.deltaTime,
	0,
	true,
	);
	});
	rightKey.addEventListener("holding", (event) => {
	cameraControls.rotate(
	0.05 * THREE.MathUtils.DEG2RAD * event?.deltaTime,
	0,
	true,
	);
	});
	upKey.addEventListener("holding", (event) => {
	cameraControls.rotate(
	0,
	-0.05 * THREE.MathUtils.DEG2RAD * event?.deltaTime,
	true,
	);
	});
	downKey.addEventListener("holding", (event) => {
	cameraControls.rotate(
	0,
	0.05 * THREE.MathUtils.DEG2RAD * event?.deltaTime,
	true,
	);
	});
