In this paper we show how XSLT and aspect-oriented programming can be used to implement retargetable compilers. New devices can be specified using an XML-based device specification language. A retargeting generator produces a new compiler from this specification, actually it only produces a device specific kernel which is used by the compiler. Both the retargeting generator and the generated co...

A key disadvantage of blendshape animation is the labor-intensive task of sculpting blendshapes with individual expressions for each character. In this paper, we propose a novel system ”Character Transfer”, that automatically sculpts blendshapes with individual expressions by extracting them from training examples; this extraction creates a mapping that drives the sculpting process. Comparing o...

This paper presents a reusable model for rapid animation of the walkcycle of virtual biped characters, with implicit retargeting of motion capture to any character, regardless of dimensions. Despite modern software continuously improving the quality of automatic assistance, the process of animating a biped character still requires substantial manual intervention. Our research contributes to thi...

BACKGROUND In this paper we present a novel scene retargeting technique to reduce the visual scene while maintaining the size of the key features. The algorithm is scalable to implementation onto portable devices, and thus, has potential for augmented reality systems to provide visual support for those with tunnel vision. We therefore test the efficacy of our algorithm on shrinking the visual s...

Artists and scientists require tools to construct physics-based animal models. However, animating these models requires motion data for realistic movement. Motion data may either be measured from real-life animals-in-motion or generated using an optimisation approach. We propose a solution for retargeting gait data from one animal to another. The retargeted gait cycles are generated using a Gra...

AIthough it is generally agreed that bidirectional heuristic search is potentially more efficient than unidirectional heuristic search, so far there have been no algorithms which realize this potential. The basic difficulty is that the two search trees (one rooted at the start, the other at the goal) do not meet in the middle. This results in essentiofly two unidirectional starches and poorer p...

Methods for optical motion capture often require timeconsuming manual processing before the data can be used for subsequent tasks such as retargeting or character animation. These processing steps restrict the applicability of motion capturing especially for dynamic VR-environments with real time requirements. To solve these problems, we present two additional, fast and automatic processing sta...
