CHARM aims to model a 3D human body in order to obtain a physically based simulation of movements and deformations. We will model bones and soft tissues structures such as muscles, skin and fat, and define associated simulation procedures allowing the deformation of the final surfaces. Starting from the basic layer of the topology of anatomical structures, including the inner fibre orientation of the muscles, the surfaces will be parametrically fitted to medical images to obtain an anatomically validated database. Concurrently, mechanical models of soft tissues deformation and muscle contraction will be based on physiological data. This object-oriented library of models and methods will be complemented by high level control interfaces and rendering tools.
APPROACH AND METHODS
CHARM will include both the data description and methods encapsulated as usable computer programs. The model and methods will provide a resource for researchers in diverse fields to extract applicable information connected with the human body and its function. CHARM will be accessible to users across Europe by means of an electronic network. The most important parts of this project are as follows:
- a topological modeller consisting in an interactive software for the modelling of the human body.
- interactive software allowing the adjustment of the model to cross-sections obtained from real images
- the construction of an effective human body using the above software
- models for solving equations for tissue deformation and muscle contraction
- identification of the model for medical imaging data
- a high-level motion controller
- validation tasks
- primitives for applications
- volumetric rendering of the human body.
The final result of the project will be an integrated prototype software to obtain the physically-based simulation of movements and deformations of a 3D solid human body with bones and soft tissues structures such as muscles, skin, and fat.
The final results cab be used in applications requiring a computer-aided tool for visualising the teaching of the anatomy and physiology of the human body. In the exploitation of the results, we want to emphasise the potential use of CHARM for medical applications (based on the cooperation of medical teams) in the areas of robotised operation and rehabilitation, sport education and training, and for the entertainment industry through computer animation.
