Matrix4f nanogui::lookAt(const Vector3f &origin, const Vector3f &target, const Vector3f &up)

Creates a “look at” matrix that describes the position and orientation of e.g. a camera.

Warning

These are used to form an orthonormal basis. The first basis vector is defined as f = (target - origin).normalized().

Parameters

• origin: The position of the camera.

• target: The gaze target of the camera.

• up: The up vector of the camera.
