DXVEC structure

Describes either a continuous or a discrete four-dimensional (4-D) vector.

Syntax

typedef struct DXVEC {
  DXBNDTYPE eType;
  union {
    long     D[4];
    LONGLONG LD[4];
    float    C[4];
    double   LC[4];
  };
} DXVEC;

Members

• eType
  DXBNDTYPE enumeration that specifies which member of the union to use.

• D
  Discrete, 32-bit 4-D vector.

• LD
  Discrete, 64-bit 4-D vector.

• C
  Continuous, 32-bit 4-D vector.

• LC
  Continuous, 64-bit 4-D vector.

Remarks

Four-dimensional vectors consist of an x-coordinate, a y-coordinate, a z-coordinate, and a time coordinate.
