PxVec4T#

Defined in include/foundation/PxVec4.h

template<class Type> class PxVec4T#

4 Element vector class.

This is a 4-dimensional vector class with public data members.

Public Functions

inline PxVec4T()#: default constructor leaves data uninitialized.

inline PxVec4T(PxZERO)#: zero constructor.

inline explicit PxVec4T(Type a)#

Assigns scalar parameter to all elements.

Useful to initialize to zero or one.

Parameters:: a – [in] Value to assign to elements.

inline PxVec4T(Type nx, Type ny, Type nz, Type nw)#

Initializes from 3 scalar parameters.

Parameters:

nx – [in] Value to initialize X component.
ny – [in] Value to initialize Y component.
nz – [in] Value to initialize Z component.
nw – [in] Value to initialize W component.

inline PxVec4T(const PxVec3T<Type> &v, Type nw)#

Initializes from 3 scalar parameters.

Parameters:

v – [in] Value to initialize the X, Y, and Z components.
nw – [in] Value to initialize W component.

inline explicit PxVec4T(const Type v[])#

Initializes from an array of scalar parameters.

Parameters:: v – [in] Value to initialize with.

inline PxVec4T(const PxVec4T &v)#: Copy ctor.

inline PxVec4T &operator=(const PxVec4T &p)#: Assignment operator.

inline Type &operator[](unsigned int index)#: element access

inline const Type &operator[](unsigned int index) const#: element access

inline bool operator==(const PxVec4T &v) const#: returns true if the two vectors are exactly equal.

inline bool operator!=(const PxVec4T &v) const#: returns true if the two vectors are not exactly equal.

inline bool isZero() const#: tests for exact zero vector

inline bool isFinite() const#: returns true if all 3 elems of the vector are finite (not NAN or INF, etc.)

inline bool isNormalized() const#: is normalized - used by API parameter validation

inline Type magnitudeSquared() const#

returns the squared magnitude

Avoids calling PxSqrt()!

inline Type magnitude() const#: returns the magnitude

inline PxVec4T operator-() const#: negation

inline PxVec4T operator+(const PxVec4T &v) const#: vector addition

inline PxVec4T operator-(const PxVec4T &v) const#: vector difference

inline PxVec4T operator*(Type f) const#: scalar post-multiplication

inline PxVec4T operator/(Type f) const#: scalar division

inline PxVec4T &operator+=(const PxVec4T &v)#: vector addition

inline PxVec4T &operator-=(const PxVec4T &v)#: vector difference

inline PxVec4T &operator*=(Type f)#: scalar multiplication

inline PxVec4T &operator/=(Type f)#: scalar division

inline Type dot(const PxVec4T &v) const#: returns the scalar product of this and other.

inline PxVec4T getNormalized() const#: returns a unit vector

inline Type normalize()#: normalizes the vector in place

inline PxVec4T multiply(const PxVec4T &a) const#: a[i] * b[i], for all i.

inline PxVec4T minimum(const PxVec4T &v) const#: element-wise minimum

inline PxVec4T maximum(const PxVec4T &v) const#: element-wise maximum

inline PxVec3T<Type> getXYZ() const#
