• GLM_FUNC_DECL qua< T, Q >
  mix (qua< T, Q > const &x, qua< T, Q > const &y, T a)

  Spherical linear interpolation of two quaternions. The interpolation is oriented and the rotation is performed at constant speed. For short path spherical linear interpolation, use the slerp function.

  x

  A quaternion

  y

  A quaternion

  a

  Interpolation factor. The interpolation is defined beyond the range [0, 1].

  T

  A floating-point scalar type

  Q

  A value from qualifier enum

• GLM_FUNC_DECL qua< T, Q >
  slerp (qua< T, Q > const &x, qua< T, Q > const &y, T a)

  Spherical linear interpolation of two quaternions. The interpolation always take the short path and the rotation is performed at constant speed.

• GLM_FUNC_DECL vec< 4, bool, Q >
  isnan (qua< T, Q > const &x)

  Returns true if x holds a NaN (not a number) representation in the underlying implementation's set of floating point representations. Returns false otherwise, including for implementations with no NaN representations.

  /!\ When using compiler fast math, this function may fail.

  Q

  A value from qualifier enum

• GLM_FUNC_DECL vec< 4, bool, Q >
