Virtual Wind-up Toys for Animation

چکیده
We propose a new method of automatically finding periodic modes of locomotion for arbitrary articulated figures. Cyclic pose control graphs are used as our control representation. These specifically constrain the controller synthesis process to only those controllers producing periodic driving functions. It is shown that stochastic generate-and-test techniques work well with this representation. Several choices that arise in this synthesis technique are explored. The impact of the design of the physical models upon the motions produced is examined. Lastly, the motions produced are analysed by looking at their bifurcation diagrams.

An Implementation on Real-time Animation of Trees Swaying in Wind Fields
Trees are one of the most important objects of everyday life. Therefore, it is really crucial to have a realistic tree animation, especially for virtual reality applications. Many studies have been made on simulating tree motion under influence of wind. Most of the time, those studies use physical based approaches to generate the branch motions. In this paper, I propose a hybrid method to creat...
متن کاملDetermining the Effective Distance of Wind Shelter Index by Defining Innovative Index Named Virtual Wind Shelter in a Non-Snowy Watershed
The wind’s effectiveness was compared in different points of a watershed using a quantity called The Wind Shelter Index.The wind’s effectiveness was compared in different points of a watershed using a quantity called The Wind Shelter Index. It is necessary to choose a distance called the effective distance in the process of this index determination. The criterion already used for this purpose w...
متن کاملRandomly Accessible Procedural Animation of Physically Approximate Turbulent Motion
Complex virtual environments can be simulated with physical or procedural motion. Physical motion is more realistic, but requires the integration of an ordinary differential equation from an initial state. Procedural motion has the advantage of being randomly accessible, though it is not physically based. We combine these techniques into a multiresolution model. A coarse-level simulation is sam...
متن کاملReal-time fur simulation and rendering
Real-time simulation of fur is a key element inmany virtual reality applications. However, it is still difficult to simulate effects of fur animation in real-time. In this paper, we propose an interactive fur simulation method, to calculate effects of external forces, such as wind and gravity, and direct manipulation for real-time interactive animation. The proposed method consists of two layer...
متن کاملTwo approaches to Scripting Character Animation
Lifelike animated agents present a challenging ongoing agenda for research. Such agent metaphors will only be widely applicable to on-line applications when there is a standardised way to map underlying engines with the visual presentation of the agents. This paper delineates functions and specifications of two mark-up languages for scripting the animation of virtual characters. These languages...
