Struttura D3DXVECTOR4 (D3DX10Math.h)

Nota

La libreria di utilità D3DX10 è deprecata. È consigliabile usare invece DirectXMath .

Descrive un vettore a quattro componenti, inclusi gli overload degli operatori e i cast dei tipi.

Sintassi

typedef struct D3DXVECTOR4 {
  FLOAT x;
  FLOAT y;
  FLOAT z;
  FLOAT w;
} D3DXVECTOR4, *LPD3DXVECTOR4;

Members

x

Tipo: FLOAT

Componente x.

y

Tipo: FLOAT

Componente y.

Z

Tipo: FLOAT

Componente z.

w

Tipo: FLOAT

Componente w.

Commenti

D3DXVECTOR4 include le estensioni C++ seguenti.
