Physically Based Modelling of Human Limbs
نویسندگان
چکیده
This paper considers the modelling of human limbs featuring deformable tissue, which automatically exhibit realistic behaviour when simulated in a synthetic environment. A limb model is proposed that incorporates a simple skeleton joint, muscle tissue, non-muscle tissue (e.g. fat), tendons and a skin layer. The only input parameters to the model are for simple low-level control of muscle activation, with the resulting motion and deformation of the limb being generated automatically. To demonstrate the approach we have implemented a preliminary model of the limb which incorporates a new mass-spring-damper model based on octahedral elements for modelling the deformable tissue. The results show eeects that occur in real limbs such as bulging and creasing at joints.

The Role of Religious Attitudes in Mental Health of Physically-Disabled Individuals
Achieving mental health is one of the most basic guidelines of religious teachings, and this will not be possible except with divine attitude. Physically-disabled individuals are one of the most important target groups that can achieve optimal mental attitudes through correct attitudes. Therefore, this research seeks to answer the question “what are the attitudes, presented in religious teachin...
متن کاملRepresentation of Human Gait Trajectory through Temporospatial Image Modelling
Marker-based 2D temporospatial image modelling is a common strategy in characterizing human gait where Channel filtering, Threshold imaging, and Line feel algorithm are normally used in foreground segmentation targeting human lower limbs of a particular image frame. This paper presents Temporospatial Image Modelling approach in presenting segmented objects with spatiotemporal view by reflecting...
متن کاملComputerized analysis and modelling of patients with deformities of lower limbs.
The purpose of this paper was to model the human gait of typical subjects and patients with such deformities of lower limbs as: spastic diplegia cerebral palsy and spina bifida occulta. Model coefficients will lead to the development of a better computer system to support clinical decision-making in human gait in terms of assessment, diagnosis, and classification. Human gait was evaluated by us...

متن کاملPredicting the Structural Performance of Heat-Treatable Al-Alloys
Advances in physically-based and adaptive numeric modelling (ANM) have lead to a significant elevation of the role of modelling in commercial alloy development and process optimisation. Within these two categories of modelling a wide variety of techniques exists, whilst hybrid approaches, taking advantage of the benefits of the both methods, are also being developed. In this paper various ANM t...
