3D interactive simulation of arma-brown gyrocompass based on VRML

Gyrocompass is an important instrument of vessels, but its complex three-dimensional structure and principle of pointing towards the North is a bottleneck to gyrocompass learners. The sensitive element and follow-up element of Arma-Brown MK10 gyrocompass are simulated by virtual reality modeling language VRML. Three-dimensional interactive demonstrations of this gyrocompass´ structure and principle of pointing towards the North are implemented. So learners will have a direct cognition to gyrocompass´s structure and clearly understand the process of pointing towards the North stably of spin axis. The realization process of simulation in the virtual reality environment is described in detail and the relevant source codes are given.
