Zoom via Button?

I am not too much into react, but the smooth camera motion was solved here:

How to change camera location and rotation smoothly

Looking up the starting value is a little trickier when the target property is nested (e.g. “rotation.x”). Here’s code to do it that I derived from the RuntimeAnimation’s _preparePath function. Edit: couldn’t resist simplifying it a little more.

If I understand your first problem correctly, you want to change 1 to distance between camera and mesh? Then you could simply use:

BABYLON.Vector3.Distance(camera.position, mesh.absolutePosition)

Regarding ArcRotate- and “other”-Cameras you might want to have a look at this, how position and rotation is set when you switch camera:

Same camera on switch

Corresponding to your case, I would set target of arc camera as target of universal: universalCamera.setTarget(arcCamera.target) In case of switching from arc to universal: arcCamera.setTarget(universalCamera.getFrontPosition(arcCamera.radius)) The Playground: Note: There might be special edge case on arcCamera.beta === 0, so that arc camera flips, because it only has an upVector and no forwardVector.
