tailieunhanh - Stride Space: Humanoid walking animation interpolation using 3D Delaunay databases

The objectives for this project were essentially straightforward: design an interactive web-based application (as opposed to the creation and modification of a website) that facilitates user-initiated graphic design historical content within the structure of a timeline. The central theme for the web application is the timeline – and this is where the Graphic Design History Interactive Timeline (GDHit) differs from Wikipedia, , or other user-generated databases. The content is filtered chronologically, and thus the user is always able to view the chosen event within its context. Configuring content chronologically was central to the timeline in order for it to be. | Stride Space Humanoid walking animation interpolation using 3D Delaunay databases Sybren A.

Stuvel Acknowledgements I would like to thank all the people that have made this research possible. Special thanks go to Dr. Ir. Arjan Egges who has introduced me to motion capture techniques given me a scientific basis in the field of computer animation and provided the concept for this research. I thank MSc. Ben van Basten for his help and interesting discussions and Drs. Arno Kamphuis for his critical and sometimes different point of view. Additionally I would like to thank Ton Rosendaal and the Blender community for carefully and energetically fathering and developing Blender which I have used extensively throughout my research. And Albert Heijn for their excellent Perla Dark Roast beans. Finally I thank my girlfriend parents and friends for their inspiration support enthusiasm and fondness for elegance.

Stuvel Abstract Precise control over foot placement during character locomotion is crucial to avoid obstacle collision and to produce natural results. We present a new exact parameterization technique for generating humanoid walking animations. Given a database of pre-recorded motion capture data we generate new animations using a spanning neighbours search in a Delaunay database and interpolating those neighbours. Our approach results in exact foot placement while soft constraints such as timing are also taken in account due to a novel blend candidates selection strategy. We show that this can be done very efficiently as to be compatible with real-time applications. Keywords computer animation generation interpolation real-time walk Stride Space interpolation
