HPS::Quaternion

class HPS::Quaternion

Public Functions

inline Quaternion Spline(Quaternion const &in_previous, Quaternion const &in_next) const

Calculate a control point to be used in spline interpolation

Parameters
  • in_previous – The control point before this

  • in_next – The control point after this

Returns

Resultant spline control point

inline Quaternion Squad(Quaternion const &in_right, Quaternion const &in_control1, Quaternion const &in_control2, float in_fraction) const

Spherical cubic interpolation between two Quaternions

Parameters
  • in_right – The Quaternion for interpolation.

  • in_control1 – The first control point.

  • in_control2 – The second control point.

  • in_fraction – Interpolation distance (0 - 1).

Returns

Result of interpolation.

Public Static Functions

static inline Quaternion ComputeRotation(float in_degrees, HPS::Vector const &in_axis)

Computes a quaternion from a rotation about an axis.

Parameters
  • in_degrees – The angle in degrees to rotate.

  • in_axis – The axis to rotate about.

Returns

The resulting Quaternion object.

static inline Quaternion ComputeRotation(float in_x, float in_y, float in_z)

Computes a quaternion from a rotation around the primary axes.

Parameters
  • in_x – The number of degrees to rotate around the x-axis.

  • in_y – The number of degrees to rotate around the y-axis.

  • in_z – The number of degrees to rotate around the z-axis.

Returns

The resulting Quaternion object.
