Gimbal Model
written by Fu-Kwun Hwang and Loo Kang Wee
The Gimbal Model illustrates the pitch, roll and yaw of a 3D object. Independent axis mode allows each axes to be rotated without affecting the others axes.  If this mode is not selected, the model can be used to explore the phenomena of gimbal lock.  This model tests the Java 3D  implementation of the EJS 3D library.  If the Java 3D option is selected, a airplane VMRL file (wrl) is rendered inside the gimbals. A warning message will appear if the Java 3D library is not available.

The Gimbal Model was developed using the Easy Java Simulations (EJS) modeling tool.  It is distributed as a ready-to-run (compiled) Java archive.   Double clicking the ejs_ntnu_Gimbal.jar file will run the program if Java is installed.  You can modify this simulation if you have EJS installed by right-clicking within the map and selecting "Open Ejs Model" from the pop-up menu item.

Please note that this resource requires Java3D.
