Dynamic skin deformation simulation using musculoskeletal model and soft tissue dynamics

Computational Visual Media 2017年第1期3卷 49-60页

Deformation of skin and muscle is essential for bringing an animated character to life. This deformation is difficult to animate in a realistic fashion using traditional techniques because of the subtlety of the skin deformations that must move appropriately for the character design. In this paper, we present an algorithm that generates natural, dynamic, and detailed skin deformation(movement and jiggle) from joint angle data sequences. The algorithm has two steps: identification of parameters for a quasi-static muscle deformation model, and simulation of skin deformation. In the identification step, we identify the model parameters using a musculoskeletal model and a short sequence of skin deformation data captured via a dense marker set. The simulation step first uses the quasi-static muscle deformation model to obtain the quasi-static muscle shape at each frame of the given motion sequence(slow jump). Dynamic skin deformation is then computed by simulating the passive muscle and soft tissue dynamics modeled as a mass–spring–damper system. Having obtained the model parameters, we can simulate dynamic skin deformations for subjects with similar body types from new motion data. We demonstrate our method by creating skin deformations for muscle co-contraction and external impacts from four different behaviors captured as skeletal motion capture data. Experimental results show that the simulated skin deformations are quantitatively and qualitatively similar to measured actual skin deformations.

Workplace mistreatment: Health, working environment and social and economic factors

引用

Health 2014年第5期6卷 392-403页

作者： Margaret hodgins Health Promotion Research Centre National University of Ireland Galway Ireland

Objective: To explore patterns of workplace mistreatment, relationships with health and with selected workplace, economic and social factors in 34 countries. Methods: Secondary data analysis of the European Working Conditions Survey. Results: Patterns of ill treatment (across occupational groups, and sectors) were broadly consistent with smaller, less representative studies. Prevalence was lower than many studies but corresponds with estimates of serious mistreatment. Mistreatment increases the risk of both physical and mental ill health and is associated with a range of work environment factors. Mistreatment is more prevalent in countries with smaller gender gaps, better performance on the GINI index for income inequality and for countries with specific anti-bullying legislation. Conclusions: Mistreatment in work is complex, and interventions are required at the level of the organization. Implementation issues need to be addressed, as specific anti-bullying legislation does not appear to provide sufficient protection.
