Re: [JAVA3D] WandViewBehavior in ConfiguredUniverse

[Ahmed Bayyari]

Thx for the fast reply Paul. I'm being able to grab and move the objects using the wand....but i can't perform any scaling, rotation, or translation. Not sure why. It's reading all my button values, it's just not interpreting them for the scale and rotate behaviors.

 

Here is my config file, it'll be great if someone can find what's wrong with it:

 

(NewDevice      glasses    TrackerInputDevice)

// Create logical names for the available sensors in the specified input
// devices.  The last argument is the sensor's index in the input device.
//
(NewSensor head    glasses 0)

// Set the 6DOF mouse sensor hotspot in the local sensor coordinate system.
(SensorAttribute wand Hotspot (0.0 0.0 -0.10))

 

// Create a view platform behavior for the 6DOF sensor.
