| plSimdQuat (const plSimdVec4f &v) |
| |
|
void | Normalize () |
| | Normalizes the quaternion to unit length. ALL rotation-quaternions should be normalized at all times (automatically).
|
| |
| plResult | GetRotationAxisAndAngle (plSimdVec4f &ref_vAxis, plSimdFloat &ref_fAngle, const plSimdFloat &fEpsilon=plMath::DefaultEpsilon< float >()) const |
| | Returns the rotation-axis and angle (in Radians), that this quaternion rotates around.
|
| |
|
plSimdMat4f | GetAsMat4 () const |
| | Returns the Quaternion as a matrix.
|
| |
|
bool | IsValid (const plSimdFloat &fEpsilon=plMath::DefaultEpsilon< float >()) 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 plSimdQuat &qOther, const plSimdFloat &fEpsilon) const |
| | Determines whether this and qOther represent the same rotation. This is a rather slow operation.
|
| |
|
plSimdQuat | operator- () const |
| | Returns a Quaternion that represents the negative / inverted rotation.
|
| |
|
plSimdVec4f | operator* (const plSimdVec4f &v) const |
| | Rotates v by q.
|
| |
|
plSimdQuat | operator* (const plSimdQuat &q2) const |
| | Concatenates the rotations of q1 and q2.

|
static const plSimdQuat | MakeIdentity () |
| | Static function that returns a quaternion that represents the identity rotation (none).
|
| |
| static plSimdQuat | MakeFromElements (plSimdFloat x, plSimdFloat y, plSimdFloat z, plSimdFloat 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 plSimdQuat | MakeFromAxisAndAngle (const plSimdVec4f &vRotationAxis, const plSimdFloat &fAngle) |
| | Creates a quaternion from a rotation-axis and an angle (angle is given in Radians or as an plAngle)
|
| |
|
static plSimdQuat | MakeShortestRotation (const plSimdVec4f &vDirFrom, const plSimdVec4f &vDirTo) |
| | Creates a quaternion, that rotates through the shortest arc from "vDirFrom" to "vDirTo".
|
| |
|
static plSimdQuat | MakeSlerp (const plSimdQuat &qFrom, const plSimdQuat &qTo, const plSimdFloat &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 an plAngle)
- 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.
