Detailed Description

Stores a 2x2 matrix of double elements. A basic type.

Matrices are defined to be in row-major order, so matrix[i][j] indexes the element in the i th row and the j th column.

Constructor & Destructor Documentation

GfMatrix2d::GfMatrix2d ( )

default

Default constructor. Leaves the matrix component values undefined.

GfMatrix2d::GfMatrix2d	(	double	m00,
		double	m01,
		double	m10,
		double	m11
	)

inline

Constructor. Initializes the matrix from 4 independent double values, specified in row-major order. For example, parameter m10 specifies the value in row 1 and column 0.

Definition at line 58 of file matrix2d.h.

GfMatrix2d::GfMatrix2d ( const double m[2][2] )

inline

Constructor. Initializes the matrix from a 2x2 array of double values, specified in row-major order.

Definition at line 84 of file matrix2d.h.

GF_API GfMatrix2d::GfMatrix2d ( const std::vector< std::vector< double > > & v )

explicit

Constructor. Initialize the matrix from a vector of vectors of double. The vector is expected to be 2x2. If it is too big, only the first 2 rows and/or columns will be used. If it is too small, uninitialized elements will be filled in with the corresponding elements from an identity matrix.

GF_API GfMatrix2d::GfMatrix2d ( const std::vector< std::vector< float > > & v )

explicit

Constructor. Initialize the matrix from a vector of vectors of float. The vector is expected to be 2x2. If it is too big, only the first 2 rows and/or columns will be used. If it is too small, uninitialized elements will be filled in with the corresponding elements from an identity matrix.

GF_API GfMatrix2d::GfMatrix2d ( const class GfMatrix2f & m )

explicit

This explicit constructor converts a "float" matrix to a "double" matrix.
