Estructura D3DXVECTOR3 (D3dx9math.h)

Nota

La biblioteca de utilidades D3DX está en desuso. Se recomienda usar DirectXMath en su lugar.

Describe un vector de tres componentes, incluidas las sobrecargas de operador y las conversiones de tipos.

Sintaxis

typedef struct D3DXVECTOR3 {
  FLOAT x;
  FLOAT y;
  FLOAT z;
} D3DXVECTOR3, *LPD3DXVECTOR3;

Miembros

x

Tipo: FLOAT

Componente x.

y

Tipo: FLOAT

Componente y.

z

Tipo: FLOAT

Componente z.
