Welcome to ArtiSynth
A 3D Biomechanical Modeling Toolkit for
Physical Simulation of Anatomical Structures

ArtiSynth is a 3D biomechanical simulation platform being developed at the University of British Columbia, Canada. Implemented in Java, it provides an open-source, cross-platform environment in which researchers can create and interconnect various kinds of dynamic and parametric models to form complete integrated models of anatomical structures. Models can be built from a rich set of components, including particles, rigid bodies, finite elements with both linear and nonlinear materials, point-to-point muscles, and various bilateral and unilateral constraints including contact. A graphical interface allows interactive component navigation, model editing, and simulation control. To date, most applications of ArtiSynth have been directed toward modeling the anatomy of the oral and upper airway region. Existing models include jaw, hyoid, and tongue structures, and these are being extended to include the soft palate, larynx, and pharyngeal wall. ArtiSynth is the simulation platform for the OPAL project, and has also been used to create airway models for use in articulatory speech synthesis.

ArtiSynth provides a range of simulation capabilities that can be used for both general mechanical as well as biomechanical modeling:

One of our state-of-the-art models is a coupled model of the jaw, hyoid, and tongue, which was built in collaboration with Yohan Payan and the GIPSA Lab in Grenoble, France, and which is currently being extended to include the face:

Primary development of ArtiSynth is being undertaken by the Department of Electrical and Computer Engineering and the Department of Computer Science at the University of British Columbia.
