| xiiSimdQuatd (const xiiSimdVec4d &v) |
| |
|
void | Normalize () |
| | Normalizes the quaternion to unit length. ALL rotation-quaternions should be normalized at all times (automatically).
|
| |
| xiiResult | GetRotationAxisAndAngle (xiiSimdVec4d &ref_vAxis, xiiSimdDouble &ref_fAngle, const xiiSimdDouble &fEpsilon=xiiMath::DefaultEpsilon< double >()) const |
| | Returns the rotation-axis and angle (in Radians), that this quaternion rotates around.
|
| |
|
xiiSimdMat4d | GetAsMat4 () const |
| | Returns the Quaternion as a matrix.
|
| |
|
bool | IsValid (const xiiSimdDouble &fEpsilon=xiiMath::DefaultEpsilon< double >()) const |
| | Checks whether all components are neither NaN nor infinite and that the quaternion is normalized.
|
| |
|
bool | IsNaN () const |
| | Checks whether any component is NaN.
|
| |
| bool | IsEqualRotation (const xiiSimdQuatd &other, const xiiSimdDouble &fEpsilon) const |
| | Determines whether this and qOther represent the same rotation. This is a rather slow operation.
|
| |
|
xiiSimdQuatd | operator- () const |
| | Returns a Quaternion that represents the negative / inverted rotation.
|
| |
|
xiiSimdVec4d | operator* (const xiiSimdVec4d &v) const |
| | Rotates v by q.
|
| |
|
xiiSimdQuatd | operator* (const xiiSimdQuatd &q2) const |
| | Concatenates the rotations of q1 and q2.
|
| |
|

| |
|
bool | operator!= (const xiiSimdQuatd &q2) const |

|
static const xiiSimdQuatd | MakeIdentity () |
| | Static function that returns a quaternion that represents the identity rotation (none).
|
| |
| static xiiSimdQuatd | MakeFromElements (xiiSimdDouble x, xiiSimdDouble y, xiiSimdDouble z, xiiSimdDouble w) |
| | Sets the individual elements of the quaternion directly. Note that x,y,z do NOT represent a rotation axis, and w does NOT represent an angle.
|
| |
| static xiiSimdQuatd | MakeFromAxisAndAngle (const xiiSimdVec4d &vRotationAxis, const xiiSimdDouble &fAngle) |
| | Creates a quaternion from a rotation-axis and an angle (angle is given in Radians or as a xiiAngle)
|
| |
|
static xiiSimdQuatd | MakeShortestRotation (const xiiSimdVec4d &vDirFrom, const xiiSimdVec4d &vDirTo) |
| | Creates a quaternion, that rotates through the shortest arc from "vDirFrom" to "vDirTo".
|
| |
|
static xiiSimdQuatd | MakeSlerp (const xiiSimdQuatd &qFrom, const xiiSimdQuatd &qTo, const xiiSimdDouble &t) |
| | Returns a quaternion that is the spherical linear interpolation of the other two.

◆ GetRotationAxisAndAngle()
Returns the rotation-axis and angle (in Radians), that this quaternion rotates around.
- Todo
- optimize
◆ IsEqualRotation()
Determines whether this and qOther represent the same rotation. This is a rather slow operation.
Currently it fails when one of the given quaternions is identity (so no rotation, at all), as it tries to compare rotation axis' and angles, which is undefined for the identity quaternion (also there are infinite representations for 'identity', so it's difficult to check for it).
◆ MakeFromAxisAndAngle()
Creates a quaternion from a rotation-axis and an angle (angle is given in Radians or as a xiiAngle)
- Todo
- optimize
◆ MakeFromElements()
Sets the individual elements of the quaternion directly. Note that x,y,z do NOT represent a rotation axis, and w does NOT represent an angle.
Use this function only if you have good understanding of quaternion math and know exactly what you are doing.
