Describes a vector in three-dimensional (3-D) space.

Syntax

typedef struct D3DXVECTOR3 : public D3DVECTOR { public: D3DXVECTOR3() {}; D3DXVECTOR3( CONST FLOAT * ); D3DXVECTOR3( CONST D3DVECTOR& ); D3DXVECTOR3( FLOAT x, FLOAT y, FLOAT z ); // casting operator FLOAT* (); operator CONST FLOAT* () const; // assignment operators D3DXVECTOR3& operator += ( CONST D3DXVECTOR3& ); D3DXVECTOR3& operator -= ( CONST D3DXVECTOR3& ); D3DXVECTOR3& operator *= ( FLOAT ); D3DXVECTOR3& operator /= ( FLOAT ); // unary operators D3DXVECTOR3 operator + () const; D3DXVECTOR3 operator - () const; // binary operators D3DXVECTOR3 operator + ( CONST D3DXVECTOR3& ) const; D3DXVECTOR3 operator - ( CONST D3DXVECTOR3& ) const; D3DXVECTOR3 operator * ( FLOAT ) const; D3DXVECTOR3 operator / ( FLOAT ) const; friend D3DXVECTOR3 operator * ( FLOAT, CONST struct D3DXVECTOR3& ); BOOL operator == ( CONST D3DXVECTOR3& ) const; BOOL operator != ( CONST D3DXVECTOR3& ) const; } D3DXVECTOR3, *LPD3DXVECTOR3;

Members

x- The x-component.
y- The y-component.
z- The z-component.

Remarks

This structure inherits the

x,yandzmembers from the D3DVECTOR structure. C programmers cannot use theD3DXVECTOR3structure. They must use theD3DVECTORstructure.C++ programmers can take advantage of operator overloading and type casting with the D3DXVECTOR3 Extensions, which implement overloaded constructors, assignment, unary, and binary (including equality) operators.
