Lookat matrix explained

Web\$\begingroup\$ Well, considering the well known truism: "The camera transformation matrix means applying it as an inverse matrix to the poses of the objects in the scene and … WebI still don't get why Matrix4x4.LookAt gave me wrong results, since afaik it takes world-space values as inputs and outputs a worldspace-to-viewspace matrix. No, that's not what LookAt does. LookAt creates a matrix that makes an object to "looks at" a certain point in worldspace coordinates. This matrix does still convert from local to worldspace.
