Dynamic Virtual Realities with Sound Models
(1996) In MSc ThesesDepartment of Automatic Control
- Abstract
- Facilities to present simulation results as animations on the Internet have been developed. They can take simulation results from the modeling and simulation environment Dymola and convert them to a Virtual Reality Model Language (VRML) representation, which is the new Internet protocol for displaying three dimensional graphical worlds with sound effects. Mathematical models for sound have been developed in Dymola. The model for a string gives good results. However, it is much worse to model a membrane. Sound models must have high bandwiths, which require fine discretizations, which make the models large and complex. Furthermore, sound interacts in complex ways with the environment on its way to our ears. Filters that compensate for the... (More)
- Facilities to present simulation results as animations on the Internet have been developed.

Mathematical models for sound have been developed in Dymola. The model for a string gives good results. However, it is much worse to model a membrane. Sound models must have high bandwiths, which require fine discretizations, which make the models large and complex. Furthermore, sound interacts in complex ways with the environment on its way to our ears. Filters that compensate for the effects that are introduced during the propagation of the sound from the source to the receiver have been developed with good results. Software to output a general variable to a soundcard under Windows has been developed. The VRML has shown to be a great tool to model advanced virtual reality scenes including both sound and animation. In combination with Dymola, VRML can be used to present dynamic behavior including both animation and sound. (Less)
