Rotation Matrix of the world

January 9, 2019 - 7:45am #1

Hello there,

Would someone please help me to figure out the rotation matrix of the world created by Hololens?

When the application starts Hololens creates a world center at where my head is and gives it the position of (0,0,0), however

the rotation (or the direction of the axis of the world coordinate system) is missing. Is it possible to retrieve this matrix?

Best regards

Hello,

This may be a question more suitable for a HoloLens forum. That being said, all the APIs that provide translation also provide rotation so you should already have it. Our recollection is that you can easily get to either Matrix 3x3 or Quaternion in Unity.

Thanks,
