Function-based time-dependent shape modeling on the Web

In this paper we propose FVRML - a function-based extension of Virtual Reality Modeling Language which allows for time-dependent shape modeling on the Web. Shape´s geometry, 3D texture, color and transformations can be defined with analytical functions typed straight in VRML code. These analytical functions can be functions of time. FVRML allows us to greatly extend the abilities of VRML with a very intuitive approach to shape modeling based on using analytical functions. Several functions can be combined into one using Java scripts emulated in FVRML, which allows for even greater flexibility and convenience of shape modeling
