Thank you very much, Paul!
But when I tried to run your suggest, I found that It threw a not capibity
to read
Local to VWorld transform exception.
When I tried to set this capibility to the
simpleUniverse.getViewingPlatform().setCapability(vP.ALLOW_READ_LOCALTOVWORL
D)
I got the exception: Not allowed to set capabilities to a lived or compiled
Object,
but
I DIDN`T ALREADY COMPILE THE BRANCH WHICH THE SimpleUniverse!!
I used this code from the FlyBehavior of the J3DFLy Demo
yawTransform.rotY( yawAngle );
pitchTransform.rotX( pitchAngle );
rollTransform.rotZ( rollAngle );
velocityTransform.set( velocity ); //velocity es the
traslational vector
velocityTransform.mul( yawTransform );
velocityTransform.mul( pitchTransform );
velocityTransform.mul( rollTransform );
targetTG.getTransform( targetTransform );
targetTransform.mul( yawTransform );
targetTransform.mul( pitchTransform );
targetTransform.mul( rollTransform );
targetTransform.mul( velocityTransform );
targetTG.setTransform( targetTransform );
