Camera Frame selected - how to

Unity Engine
1

Hi All
I’m trying to mimic Unity’s menu command Edit->Frame Selected so I can focus the camera on the selected object.

Any pointers on how to accomplish that are very much appreciated :smile:
Thanks in advance!

couldn’t tell you how to do it in unity yet, but the basics are

the distance from the camera D so that:

D = R / sin( FOV/2 );

where R is the object’s bounding sphere radius

Thanks that’s what I needed
here’s a little snippet on how you could doit on Unity
I used a mesh collider to aproximate the object’s radius.

function FrameObject(cam: Camera, target: GameObject) {
	// D = R / sin( FOV/2 );
	if(target) {
		var c: MeshCollider = target.GetComponent("MeshCollider");
		if(c) {
			var r: float = (c.bounds.max - c.bounds.center).magnitude;
			var fov: float = cam.fieldOfView;
			var d: float = r / Mathf.Sin( Mathf.Deg2Rad * (fov*0.5) );
			distance = d + cam.nearClipPlane; 
}
	}
}

You may also want to use Transform.LookAt() to align your camera appropriately.
