PxVec3T

Defined in include/foundation/PxVec3.h

template<class Type> class PxVec3T

3 Element vector class.

This is a 3-dimensional vector class with public data members.

Public Functions

inline PxVec3T(): default constructor leaves data uninitialized.

inline PxVec3T(PxZERO): zero constructor.

inline explicit PxVec3T(Type a)

Assigns scalar parameter to all elements.

Useful to initialize to zero or one.

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

inline PxVec3T(Type nx, Type ny, Type nz)

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.

inline PxVec3T(const PxVec3T &v): Copy ctor.

inline PxVec3T &operator=(const PxVec3T &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 PxVec3T &v) const: returns true if the two vectors are exactly equal.

inline bool operator!=(const PxVec3T &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 PxVec3T operator-() const: negation

inline PxVec3T operator+(const PxVec3T &v) const: vector addition

inline PxVec3T operator-(const PxVec3T &v) const: vector difference

inline PxVec3T operator*(Type f) const: scalar post-multiplication

inline PxVec3T operator/(Type f) const: scalar division

inline PxVec3T &operator+=(const PxVec3T &v): vector addition

inline PxVec3T &operator-=(const PxVec3T &v): vector difference

inline PxVec3T &operator*=(Type f): scalar multiplication

inline PxVec3T &operator/=(Type f): scalar division

inline Type dot(const PxVec3T &v) const: returns the scalar product of this and other.

inline PxVec3T cross(const PxVec3T &v) const: cross product

inline PxVec3T getNormalized() const: returns a unit vector

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

inline Type normalizeSafe()

normalizes the vector in place.

Does nothing if vector magnitude is under PX_NORMALIZATION_EPSILON. Returns vector magnitude if >= PX_NORMALIZATION_EPSILON and 0.0f otherwise.

inline Type normalizeFast()

normalizes the vector in place.

Asserts if vector magnitude is under PX_NORMALIZATION_EPSILON. returns vector magnitude.

inline PxVec3T multiply(const PxVec3T &a) const: a[i] * b[i], for all i.

inline PxVec3T minimum(const PxVec3T &v) const: element-wise minimum

inline Type minElement() const: returns MIN(x, y, z);

inline PxVec3T maximum(const PxVec3T &v) const: element-wise maximum

inline Type maxElement() const: returns MAX(x, y, z);

inline PxVec3T abs() const: returns absolute values of components;
