Struct Quaternion

#[repr(C)]
pub struct Quaternion(pub [f32; 4]);

Datatype: A Quaternion represented by 4 real numbers.

Note: although the x,y,z,w components of the quaternion will be passed through to the datastore as provided, when used in the Viewer Quaternions will always be normalized.

Tuple Fields

0: [f32; 4]
