Description

hom_mat2d_identityhom_mat2d_identityHomMat2dIdentityHomMat2dIdentityHomMat2dIdentity generates the homogeneous transformation matrix HomMat2DIdentityHomMat2DIdentityHomMat2DIdentityHomMat2DIdentityhomMat2DIdentity describing the identical 2D transformation:

Attention

Note that homogeneous matrices are stored row-by-row as a tuple; the last row is not stored because it is identical for all homogeneous matrices that describe an affine transformation. Thus, HomMat2DIdentityHomMat2DIdentityHomMat2DIdentityHomMat2DIdentityhomMat2DIdentity is stored as the tuple [1,0,0,0,1,0].
