D3DXPLANE Structure

Describes a plane.

Syntax

typedef struct D3DXPLANE {
    FLOAT a;
    FLOAT b;
    FLOAT c;
    FLOAT 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 so that a x + b y + c z + d w = 0.

C++ programmers can take advantage of operator overloading and type casting with the D3DXPLANE Extensions which implement overloaded constructors, assignment, unary, and binary (including equality) operators.
