Tracking and interaction

[kgarr]

The are a couple things I am looking for help to get started on. I already have Vizard reading my Flock of Birds sensor on the Wanda with the trackd plugin (thanks again for that)

We are using Vizard to replace our previous scientific visualization software, due to the last programs limited abilities, but I would like to add some of the functionality from the old software to Vizard.

Navigation:
Drive Mode: The view changes with movement of the Wanda when a button is pressed (separate from head tracking). Joystick on Wanda allows for moving forward and backward.
Fly Mode: When fly mode is turned on (usually with a button) the position and orientation is stored. When the Wanda is moved, the user "flies" around the world based on the difference from the initial values.

Interaction:
Cursor: I simple 3D object could be used as a cursor. The old software had a light-saber like cursor, a red line extending from the location of the Wanda into the screen, with the tip being the cursor. It would be nice if this was possible in Vizard.
Functionality: There are 2 functions the cursors needs to be able to perform. The first is selection any object it interacts with, similar to the mouse over function, but in 3D. For example, I can use the light saber to "spear" a 3D object, and by pressing a button, the object can be moved around with the sensor. The other functionality would be to use the same 3D cursor to interact with GUI items.

Any help getting any of this started will be greatly appreciated. Thanks in advance
