D3DXVECTOR3

  • Article

This structure describes a vector in three-dimensional (3-D) space.

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, y, and z members from the D3DVECTOR structure. C programmers cannot use the D3DXVECTOR3 structure. They must use the D3DVECTOR structure.

C++ programmers can take advantage of operator overloading and type casting. The C++ implementation of the D3DXVECTOR3 structure implements overloaded constructors and overloaded assignment, unary and binary (including equality) operators. For more information, see C++ Specific Features.

Requirements

OS Versions: Windows CE .NET 4.0 and later.
Header: D3dx8math.h.
