PxTransformPadded

Defined in include/foundation/PxTransform.h

struct PxTransformPadded : public PxTransformT<float>

A generic padded & aligned transform class.

This can be used for safe faster loads & stores, and faster address computations (the default PxTransformT often generating imuls for this otherwise). Padding bytes can be reused to store useful data if needed.

Public Functions

inline void operator=(const PxTransformPadded &other)

inline void operator=(const PxTransform &other)

inline bool operator==(const PxTransformT &t) const: returns true if the two transforms are exactly equal

inline PxTransformT operator*(const PxTransformT &x) const

inline PxTransformT &operator*=(const PxTransformT &other): Equals matrix multiplication.

inline PxTransformT getInverse() const

inline PxTransformT getNormalized() const

return a normalized transform (i.e.

one in which the quaternion has unit magnitude)

inline PxVec3T<float> transform(const PxVec3T<float> &input) const

inline PxTransformT transform(const PxTransformT &src) const: Transform transform to parent (returns compound transform: first src, then *this)

inline PxVec3T<float> transformInv(const PxVec3T<float> &input) const

inline PxTransformT transformInv(const PxTransformT &src) const: Transform transform from parent (returns compound transform: first src, then this->inverse)

inline PxVec3T<float> rotate(const PxVec3T<float> &input) const

inline PxVec3T<float> rotateInv(const PxVec3T<float> &input) const

inline bool isValid() const: returns true if finite and q is a unit quaternion

inline bool isSane() const: returns true if finite and quat magnitude is reasonably close to unit to allow for some accumulation of error vs isValid

inline bool isFinite() const: returns true if all elems are finite (not NAN or INF, etc.)
