D3DXPLANE

The D3DXPLANE structure describes a plane.

typedef struct D3DXPLANE {
  float a, b, c, d;
} D3DXPLANE;

Members

a

The a coefficient of the clipping plane in the general plane equation. See remarks.

b

The b coefficient of the clipping plane in the general plane equation. See remarks.

c

The c coefficient of the clipping plane in the general plane equation. See remarks.

d

The d coefficient of the clipping plane in the general plane equation. See remarks.

Remarks

The members of the D3DXPLANE structure take the form of the general plane equation. They fit into the general plane equation such that ax + by + cz + dw = 0.

C++ programmers can take advantage of operator overloading and type casting. The C++ implementation of the D3DXPLANE structure implements overloaded constructors and overloaded unary and binary operators. For more information, see C++ Specific Features.
