Structure D3DXVECTOR4 (D3DX10Math.h)

  • Article

Notes

La bibliothèque utilitaire D3DX10 est déconseillée. Nous vous recommandons d’utiliser DirectXMath à la place.

Décrit un vecteur à quatre composants, y compris les surcharges d’opérateurs et les casts de type.

Syntaxe

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

Membres

x

Type : FLOAT

Composant x.

y

Type : FLOAT

Composant y.

z

Type : FLOAT

Composant z.

w

Type : FLOAT

Composant w.

Notes

D3DXVECTOR4 a les extensions C++ suivantes.
