Dumb math question about torque Topic is solved

[slapin]

Hi, all!
I have vertical vector

Code: Select all

Ogre::Vector3 vertical = node->_getDerivedOrientation() * Ogre::Vector3::UNIT_Y;

I need to calculate torque which will make vertical == Ogre::Vector3::UNIT_Y true or close;
how can I do it and what helpers I have to use? I thiink angular velocity will be OK too.

If (big if) I understand correctly, you're looking for this:

Code: Select all

vertical.getRotationTo(Ogre::Vector3::UNIT_Y);

which in this case should give you the same value as

Code: Select all

node->_getDerivedOrientation().Inverse()

Yes, that is perfect, thanks!
