Typedefs

Matrix Geo::MConstructQuaternion

public: Matrix MConstructQuaternion
(
    Quat q
)

Construct a matrix from a quaternion.

v128 Geo::QApplyToVec

public: v128 QApplyToVec
(
    Quat q,
    v128 v
)

Assumes q is unit.

Quat Geo::QBuildFromEulerAngles

public: Quat QBuildFromEulerAngles
(
    float x,
    float y,
    float z
)

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

Quat Geo::QBuildMatrix

public: Quat QBuildMatrix
(
    MatrixParam m
)

Construct a matrix from a quaternion.

Quat Geo::QClosestSlerp

public: Quat QClosestSlerp
(
    Quat a,
    Quat b,
    v128 s
)

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

)

Assumes q is unit.

v128 Geo::VEulerAnglesFromQuaternion

public: v128 VEulerAnglesFromQuaternion
(
    Quat q
)

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