-
template<class Type>
class PxVec2T
2 Element vector class.
This is a 2-dimensional vector class with public data members.
Public Functions
-
inline PxVec2T()
default constructor leaves data uninitialized.
-
inline PxVec2T(PxZERO)
zero constructor.
-
inline explicit PxVec2T(Type a)
Assigns scalar parameter to all elements.
Useful to initialize to zero or one.
- Parameters:
a – [in] Value to assign to elements.
-
inline PxVec2T(Type nx, Type ny)
Initializes from 2 scalar parameters.
- Parameters:
-
-
inline PxVec2T(const PxVec2T &v)
Copy ctor.
-
inline PxVec2T &operator=(const PxVec2T &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 PxVec2T &v) const
returns true if the two vectors are exactly equal.
-
inline bool operator!=(const PxVec2T &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
