template<class Type >

vcl_istream& operator>>	(	vcl_istream &	s,
		vpgl_perspective_camera< Type > &	p
	)

Read vpgl_perspective_camera from stream.

Definition at line 403 of file vpgl_perspective_camera.txx.

template<class T >

vpgl_perspective_camera<T> postmultiply	(	const vpgl_perspective_camera< T > &	in_cam,
		const vgl_h_matrix_3d< T > &	euclid_trans
	)

template<class T >

vpgl_perspective_camera<T> vpgl_align_down	(	const vpgl_perspective_camera< T > &	p0,
		const vpgl_perspective_camera< T > &	p1
	)

Changes the coordinate system of camera p1 such that the same change would transform p0 to K[I|0].

Definition at line 314 of file vpgl_perspective_camera.txx.

template<class T >

vpgl_perspective_camera<T> vpgl_align_up	(	const vpgl_perspective_camera< T > &	p0,
		const vpgl_perspective_camera< T > &	p1
	)

Changes the coordinate system of camera p1 such that the same change would transform K[I|0] to p0.

Definition at line 333 of file vpgl_perspective_camera.txx.

template<class T >

bool vpgl_perspective_decomposition	(	const vnl_matrix_fixed< T, 3, 4 > &	camera_matrix,
		vpgl_perspective_camera< T > &	p_camera
	)

Decompose camera into parameter blocks.

Attempts to decompose a 3x4 camera matrix into the parameter blocks that describe a perspective camera, but will only work if the supplied matrix has a left 3x3 submatrix with rank 3.

Definition at line 244 of file vpgl_perspective_camera.txx.

template<class T >

void vsl_b_read	(	vsl_b_istream &	is,
		vpgl_perspective_camera< T > *&	p
	)

Binary read.

template<class T >

void vsl_b_write	(	vsl_b_ostream &	os,
		const vpgl_perspective_camera< T > *	p
	)

Binary save.
