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;
``````

x

Tipo: FLOAT

Componente x.

y

Tipo: FLOAT

Componente y.

z

Tipo: FLOAT

Componente z.
