Function Documentation

vnl_matrix<double> m23d_make_ortho_projection	(	double	Ax,
		double	Ay,
		double	Az
	)

Return 2 x 3 projection matrix based on viewing from angle (Ax,Ay,Az).

If Ax=Ay=Az, then returns matrix (I|0)

vnl_matrix<double> m23d_make_ortho_projection	(	vnl_random &	r,
		unsigned	ns,
		unsigned	nm = 0,
		bool	first_is_identity = false,
		bool	basis_true = false
	)

Return projection matrix combination for ns shapes, nm modes.

Matrix is 2*ns x 3*(1+nm) in size The i,j-th sub matrix of size 2x3 corresponds to w_ij * P_i, where P_i is a projection matrix for shape i, and w_ij is the weight for the j-th shape basis.

Parameters:

first_is_identity	When true, projection for first shape is scaled identity
basis_true	When true, w_ij=(i==j) if i<=nm (ie first shapes define a basis)
