Intelligent Camera Planning for Computer Graphics - Pickering (2003) (Correct)
....Di#erential based camera planners work in dynamic environments and base their operations on the time derivative of the camera parameters. The first of these was the Throughthe Lens camera control proposed by Gleicher and Witkin [Gleicher and Witkin, 1992] and extended by Kung, Kim and Hong [Kung et al. 1995]. In these systems a user, equipped with a pointing device, picked points in a model and pinned them to the screen. The systems operation can be described by analogy to classical mechanics, the di#erence between the actual screen properties and the desired properties specified by the user is ....
....described as declarative but it required the start and stop positions to be specified for it when planning moving shots, which would require the agent requesting a shot to reason about the model world. The di#erential methods of Gleicher and Witkin [Gleicher and Witkin, 1992] Kung, Kim and Hong [Kung et al. 1995] and Marchand and Courty [Marchand and Courty, 2000] were all very e#ective but were intended to provide easier user control of a camera during interactive sessions. They did not specify an IDL and hence would require a separate picture composition package to be interfaced to a presentation ....

....the visual servoing framework, considers a local inversion of the nonlinear perspective viewing transformation. A constraint optimization is used to compute the camera velocity from the desired motion of the virtual point in the image. Another formulation of the same problem has been proposed in [11]. In both case, the image Jacobian (that links the motion of the features to camera motion) is proposed only for point features. Furthermore, the introduction of constraints in the camera trajectory is not considered within the proposed framework. The introduction of constraints has received ....

....be re evaluated each time the value of x is updated. When the Jacobian matrix J is very complex, it would disimprove the overall performance of the algorithm. In this paper, we present a simple 2m Theta 7 Jacobian matrix, which can be easily derived by a technique based on the quaternion calculus [7, 8, 9]. 2 2.2 Rank Deficiency of the Jacobian Matrix In computing the Jacobian matrix J for the perspective transformation V , the parameters (f; t x ; t y ; t z ) are free variables. This means that they can be differentiated without considering any constraints. However, the unit quaternions (q w ; q ....

The details on the derivation of Equation (4) are described in [9]. Also see [7, 8, 11] for quaternions. Given fixed 3D points p i 2 R 3 (for 3 i = 1; m) let p i (t) R q(t) p i ) be the rotated point of p i by the 3D rotation of the unit quaternion q(t) Then we have p 0 i (t) t) Theta p i (t) See [9] for more details on the ....

Keywords: Quaternion, orientation, rotation, angular velocity, hermite interpolation, animation 1 Introduction In computer graphics and animation, the rotational motion control has important applications in 3D user interface and virtual camera control [3, 11]. The 3D rotation of a solid object in R 3 can be uniquely specified by a continuous path Q(t) 2 SO(3) 0 t 1, where SO(3) is the rotation group of R 3 . Since the non Euclidean space SO(3) has many interesting geometric properties which are much different from those of Euclidean space R 3 ....
