Unigine::dmat4 Structure

Members


dmat4 ()

Default constructor that produces an identity matrix.

explicit dmat4 (const mat4 & m)

Initialization by a matrix.

Arguments

  • const mat4 & m - The value of the matrix.

explicit dmat4 (const quat & q)

Initialization by a quaternion.

Arguments

  • const quat & q - The value of the quaternion.

explicit dmat4 (const double * m, int transpose, int square)

Initialization by a pointer to the matrix.

Arguments

  • const double * m - Pointer to the matrix.
  • int transpose - If transpose is 0 (by default), the matrix is specified in the column-major style.
  • int square - If square is 0 (by default), the matrix is treated as 4x3 matrix.

dmat4 & operator*= (const dmat4 & m)

Matrix multiplication.

Arguments

  • const dmat4 & m - The value of the matrix.

Return value

The resulting matrix.

UNIGINE_INLINE double get () const

void set (const double * m, int transpose, int square)

Set matrix.

Arguments
