transform quaternion values to lightsaber rotation #2

Closed Chovin closed 4 years ago

I'd like to transform the quternion given by the phone since that seems a lot more accurate than using the gyro.

  1. into a ray that points out of the top of the phone
  2. flatten it to the x and y plane to calculate the angle

I think I need to first have the player calibrate it by having them point it toward the screen before pressing a button. This will determine which way the player is facing. hopefully it's just the quaternion multiplied by the conjugate of the quaternion gotten during calibration.

gravity is much easier to deal with. we'll use this for now 90b1424 and put this issue on the backburner

we don't get quaternions anyway on mobile browsers right now
