Hi jp,
Thanks for those suggestions. I implemented them but I am probably still doing
something wrong as the behavior is not as expected.
I used the debugger to check the values of the vectors but the numbers dont
make sense to me. Thus is the case of Down arroy key and thus I used (0, -1, 0)
as my default forward pointing vector. But what I observed is the object moving
forward and its y-value increasing instead of decreasing.
Initial position = positionArray = (132.86, 78.277, 18.48)
Initial attitude= quat = (0, 0, 0.719, 0.695)
vector = quat*(0,-1,0) = (0.99, 0.035, 0.00)
vector*2 = (1.998, 0.069, 0)
PositionArray = PositionArray + vector*2 = (134.86, 78.34, 18.48)
-------------------------------------------------------------------------------
code:
Code:
positionArray = PATCurrent->getPosition();
quat = PATCurrent->getAttitude();
vector = quat.operator *(osg::Vec3(0, 1.0, 0.0));
vector.operator *=(2);
positionArray = positionArray.operator +(vector);
PATCurrent->setPosition(positionArray);
Best,
Sanat
