TAILIEUCHUNG - Aesthetic Edits For Character Animation

Since not all the dental discolorations can be bleached effectively, it is important to recognize the etiology of discoloration and to communicate the information to the patient, along with the available treatment options, alternative treatment, and their potential outcomes. Nonvital bleaching is indicated when the discoloration is due to pulpal necrosis, pulpal hemorrhage, endodontic filling materials, or mild to moderate tetracycline most important prerequisite for internal bleaching of a tooth is the quality of the endodontic therapy. Nonvital bleaching procedure should be avoided when the root canal treatment is inadequate. Superficial enamel stains can be removed by pumice polishing, microabrasion, or an external bleaching. | Eurographics SIGGRAPH Symposium on Computer Animation 2003 D. Breen M. Lin Editors Aesthetic Edits For Character Animation Michael Neffy and Eugene Fiume Department of Computer Science University of Toronto Abstract The utility of an interactive tool can be measured by how pervasively it is embedded into a user s workflow. Tools for artists additionally must provide an appropriate level of control over expressive aspects of their work while suppressing unwanted intrusions due to details that are for the moment unnecessary. Our focus is on tools that target editing the expressive aspects of character motion. These tools allow animators to work in a way that is more expedient than modifying low-level details and offers finer control than high level directorial approaches. To illustrate this approach we present three such tools one for varying timing succession and two for varying motion shape amplitude and extent . Succession editing allows the animator to vary the activation times of the joints in the motion. Amplitude editing allows the animator to vary the joint ranges covered during a motion. Extent editing allows an animator to vary how fully a character occupies space during a movement using space freely or keeping the movement close to his body. We argue that such editing tools can be fully embedded in the workflow of character animators. We present a general animation system in which these and other edits can be defined programmatically. Working in a general pose or keyframe framework either kinematic or dynamic motion can be generated. This system is extensible to include an arbitrary set of movement edits.

Introduction Tools such as Photoshop are effective for artistic work in large part because they allow an artist to work at an appropriate level of control and because they provide rapid feedback.
