PxComputeBasisVectors

inline void PxComputeBasisVectors(const PxVec3 &dir, PxVec3 &right, PxVec3 &up)

Compute two normalized vectors (right and up) that are perpendicular to an input normalized vector (dir).

Parameters

dir – [in] is a normalized vector that is used to compute the perpendicular vectors.
right – [out] is the first of the two vectors perpendicular to dir
up – [out] is the second of the two vectors perpendicular to dir
