Struttura D3DXVECTOR2 (D3DX10Math.h)

Nota

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

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

Sintassi

typedef struct D3DXVECTOR2 {
  FLOAT x;
  FLOAT y;
} D3DXVECTOR2, *LPD3DXVECTOR2;

Members

x

Tipo: FLOAT

Componente x.

y

Tipo: FLOAT

Componente y.

Commenti

D3DXVECTOR2 include le estensioni C++ seguenti.
