Rotation Quaternions

[dankot]

Hello,
I have a SceneNode that attached to it is a regular camera.
They both are created in an existing "world".

I want to rotate the Node that I created (and with it its child camera),
using quaternions which I already hold in my memory.

I'm trying to use the node->setRotation func but I get some kind of weird yaw that is zeroed on 180 DEG.

how can I use my rotated quaternion to rotate the Irrlicht node?


Thanks ,
Dan

just to add,
that previously when I was using OGRE what I did to get the result I want now was

Code: Select all

Quaternion quat = Quaternion(Degree(45),Vector3::UNIT_Y);
yourSceneNode->setOrientation(quat);

hopes this help to get my message through.
Dan

Hello,
convert the quaternion to euler angles and use them (quaternion::toEuler)
