This structure describes a matrix.

Syntax

typedef struct _D3DMMATRIX {
  union {
    struct {
      D3DMVALUE  _11, _12, _13, _14;
      D3DMVALUE  _21, _22, _23, _24;
      D3DMVALUE  _31, _32, _33, _34;
      D3DMVALUE  _41, _42, _43, _44;
    };
    D3DMVALUE m[4][4];
  };
} D3DMMATRIX;

Members

  • _11, _12, through _44
    These 16 members correspond to individual floating-point values in a 4 x 4 matrix.
  • m
    A 4 x 4 array of floating-point values containing the contents of a 4 x 4 matrix.

Remarks

In Microsoft® Direct3D Mobile®, the _34 element of a projection matrix cannot be a negative number. If your application needs to use a negative value in this location, it should scale the entire projection matrix by 1, instead.

Requirements

Header d3dmtypes.h
Windows Embedded CE Windows CE 5.0 and later
