- Interactive authoring of bending and twisting motions of short plants using hand gestures
Kan Chen and Henry Johan
Version of Record online: 9 FEB 2017 | DOI: 10.1002/cav.1747
In this paper, we propose an approach to interactively author the bending and twisting motions of short plants using hand gestures, especially suitable for grass, flowers, and leaves. Our method is based on the observations that hand motions can represent the bending and twisting motions of short plants and using a hand to describe motions is natural and proficient for human. We therefore use a hand as a “puppet” to author the animation of one single short plant based on transferring the motions of a hand to the motions of a short plant. We first author the global motions of the short plant followed by the motions of its elements such as leaves and flowers. We also propose a framework to utilize the animation results to animate a field of short plants and further adjust the motion effects according to the properties of the short plants, such as rigidity. As a result, users can intuitively and rapidly author and generate their desired motions of short plants under the influence of external forces. Especially, our method is accessible to non-expert users and suitable for fast prototyping and authoring specific motions of short plants such as in cartoons.

- Perceptual evaluation of synthetic gaze jitter
Krzysztof Krejtz, Andrew Duchowski, Heng Zhou, Sophie Jörg and Anna Niedzielska
Version of Record online: 2 FEB 2017 | DOI: 10.1002/cav.1745
We present a procedural model to synthesize the subtleties of eye motions. Our model adds microsaccadic jitter and pupil unrest, both modeled by pink noise, to the standard main sequence. Perceptual experiments show that when the motion is data-driven or parameterized pink noise, some jitter, but not too much, is perceived as more natural than when it is excessive or absent.
- Robust standing control with posture optimization
Zumra Kavafoglu, Ersan Kavafoglu and Arjan Egges
Version of Record online: 24 JAN 2017 | DOI: 10.1002/cav.1746
We present a physics-based approach for robust center of mass shifting during standing. Desired standing posture is defined by a number of high-level features and an online optimization process calculates the kinematic postures for the lower body and the pelvis. A physics-based arm control strategy is devised for increasing the robustness of the character. The proposed approach results in robust standing motions with automatic knee-bending behavior as the character shifts its center of mass in all dimensions.
- Novel fluid detail enhancement based on multi-layer depth regression analysis and FLIP fluid simulation
Yuxing Qiu, Lipeng Yang, Shuai Li, Qing Xia, Hong Qin and Aimin Hao
Version of Record online: 13 DEC 2016 | DOI: 10.1002/cav.1741
In this paper, a novel integrated method for effective modeling and realistic enhancement of scale-sensitive fluid simulation details is proposed. The core of the method is the organic of multi-layer depth image regression analysis and fluid implicit particle fluid simulation, of which the regression analysis induces the criterion where the fluid details should be produced.
