Definitions

  • This invention concerns an animation tool suitable for use with web objects.
  • the invention is a method and system for the progressive animation of web objects.
  • the invention also concerns a transmitter and method of transmission, a receiver and method of reception, and a signal for transmission and reception.
  • a further invention involves non-linear replay of animation at the client side. This may be used where the client side parts of the primary invention are present, regardless of whether the animated sequence is being transmitted or recovered from memory.
  • a first aspect of this invention is a method for animating web objects, including the following steps: (a) Dividing an animation sequence comprising an ordered series of frames, into a plurality of strings of different frames.
  • the first string comprises one frame of the sequence, or more frames widely spaced from each other in the sequence.
  • the second string contains one or more frames, and the frames of the second string are widely spaced from each other and from the frame, or between the frames, of the first string.
  • Each successive string then contains the same number or more frames than the preceding strings, and the frames of each successive string are widely spaced from each other and between the frames of the immediately preceding string, (b) Transmitting the first string of frames.
  • a second aspect of this invention is a system for animating web objects, including:
  • Dividing means to divide an animation sequence comprising an ordered series of frames, into a plurality of strings of different frames.
  • the first string comprises one frame of the sequence, or more than one frame widely spaced from each other in the sequence.
  • the second string contains the same number or more frames than the first, and the frames of the second string are widely spaced from each other and from the frame, or between the frames, of the first string.
  • Each successive string then contains the same number or more frames than the preceding string, and the frames of each successive string are widely spaced from each other and between the frames of the immediately preceding string.
  • a transmitter to transmit the strings of frames in order, starting with the first.
  • a receiver to receive the strings of frames in order, starting with the first.
  • a multi-thread controller to display a first partial animation sequence comprising the frame, or frames, of the first string in a first thread which will repeat until it reaches its last frame and the controller kills it following reception of the second string.
  • the controller will then display a second partial animation sequence comprising the frames of the first and second string, in sequential order, in a second thread which will repeat until it reaches its last frame and is killed following reception of the next string.
  • the controller kills the last thread and displays a next animation sequence comprising all the frames of the received strings, in sequential order, in a next thread and so on until all the strings are received and the entire animation sequence is being displayed.
  • the invention is a transmitter and method of transmission, a receiver and method of reception, and a signal for transmission and reception, which each involve the appropriate features mentioned above.
  • the receiver may employ client-side buffers, progressive loading frames, and multi-thread animation.
  • the signal itself is divided into 'pyramid' structured stages. The top layer of the 'pyramid' is first transmitted with as small amount of data as possible and then the rest of the layers are transmitted progressively through each level.
  • the animator does not require special coded objects.
  • the sequence can still be in original frames, and any file format can be supported. Therefore, the single frame in the original sequence can still be referenced and used for other purposes, such as non-linear replay.
  • the animator can be easily incorporated into Web browser or attached as a plug-in processor.
  • the animator class is relatively compact (less than 6K). It has less overhead comparing with other methods of animation. It can be downloaded from remote site and activated locally, or pre-installed in the Netscape browser as a plug-in.

  • f c is the current frame number
  • (d, - d can be calculated from mouse movement.
  • the client can control the animation speed in both reverse and forward orders by simply dragging the mouse backward or forward with different speeds.
  • the speed of animation increases or decreases with the speed of mouse movement, while the frame number is displaying to provide a better way to view the animation.
  • a duration tag can be attached to each frame to define the duration of each frame, say in milliseconds. There is no extra coding needed for the frames.
  • the animation can also be controlled by a parametrical function, where a waveform, such as a sinusoid, is used to define the velocity of the animation sequence.

  • MediaTracker is used to track the loading process at each level, and synchronise loading and animation.
  • Non-Linear Control There are three ways to achieve non-linear play:

  • the client can control the animation speed in both reverse and forward orders by simply dragging the mouse backward or forward with different speeds.
  • the speed of animation increases or decreases with the speed of mouse movement, while the frame number is displaying to provide a better way to view the animation.
  • f n denotes the next frame number.
  • f c is the current frame number and (d 2 - d can be calculated from mouse movement.
  • the animation class is activated from an applet call in a html tag:
  • a sinusoid wave is used to define the velocity of the animation sequence.
  • the direct application is for animating web objects for the Internet. Although all three non-linear control modes can be used in the web environment, the most useful one is likely to be interactive control. At present, a large part of the popularity of animation is due to its novelty.
  • the animation tool can be used for animation control in commercial art studios.
  • Animation has been widely used in TV advertisements, movie production, special visual effects and visual illustrations.
  • the current approach in commercial studios needs an expensive equipment with manual control of play, stop and speed, etc.
  • non-linear editing has been widely accepted, such as Adobe Premiere. Director, etc.
  • Such software will put a high demand on non-linear animation tools.
  • the interactive control in this scheme could replace the current manual control method while the duration-tag method and the parametrical control method will add extra features for non-linear animation control.

Abstract

L'invention concerne un outil d'animation approprié à des objets Web. L'invention concerne plus particulièrement un procédé et un système destiné à l'animation progressive d'objets Web. L'invention concerne un émetteur et un procédé d'émission, un récepteur et un procédé de réception, ainsi qu'un signal d'émission et de réception. Des chaînes de trames sont divisées à partir d'une séquence d'animation comprenant une série ordonnée de trames. La première chaîne comprend une trame de la séquence, ou plusieurs trames largement espacées entre elles dans la séquence. La seconde chaîne comprend le même nombre ou plus de trames que la première, et les trames de la seconde chaîne sont largement espacées entre elles et par rapport à la trame, ou entre les trames, de la première chaîne. Chaque chaîne successive comprend ensuite le même nombre ou plus de trames que la chaîne précédente, et les trames de chaque chaîne successive sont largement espacées entre elles dans la séquence et entre les trames de la chaîne les précédant immédiatement. Les chaînes sont émises et, dès leur réception, elles sont affichées. D'abord, une première séquence d'animation partielle comprenant la ou les trames de la première chaîne dans un premier fil est affichée de manière répétée jusqu'à ce qu'il atteigne la dernière trame et soit tué. Suite à la réception de la seconde chaîne, une seconde séquence d'animation partielle comprenant les trames de la première et de la seconde chaîne, en ordre séquentiel, est affichée dans un second fil qui se répétera jusqu'à ce la dernière trame soit atteinte et qui sera tué suite à la réception de la chaîne suivante. Ensuite, dès que chaque chaîne suivante est reçue et que le dernier fil atteint sa dernière trame, le dernier fil est tué et une séquence d'animation suivante comprenant toutes les trames des chaînes reçues, en ordre séquentiel, est affichée dans un fil suivant et ainsi de suite jusqu'à ce toutes les chaînes soient reçues et que toute la séquence d'animation soit affichée.
