    Functions

    Name Description
    MConstructQuaternion(Quat)

    Construct a matrix from a quaternion.

    QApplyToVec(Quat, v128)

    Assumes q is unit.

    QBuildFromEulerAngles(float, float, float)

    Converts quaternion into euler angles in XYZ order, stored in those components.

    QBuildMatrix(MatrixParam)

    Construct a matrix from a quaternion.

    QClosestSlerp(Quat, Quat, v128)

    Flips inputs to be on the same hyper-hemisphere. Use QFullSlerp if desired.

    QConjugate(Quat)

    q* = -xyz, +w

    QFullSlerp(Quat, Quat, v128)

    Does not flip inputs to be on the same hyper-hemisphere. Use QClosestSlerp if desired.

    QIdentity()

    q* = -xyz, +w

    QLerp(Quat, Quat, v128)

    Assumes a and b are unit.

    QMul(Quat, Quat)

    quat multiply.

    QSqrt(Quat)

    Assumes q is unit.

    VEulerAnglesFromQuaternion(Quat)

    Converts quaternion into euler angles in XYZ order, stored in those components.
