Short description🔗

hom_mat3d_identityHomMat3dIdentityHomMat3dIdentityhom_mat3d_identityT_hom_mat3d_identity — Generate the homogeneous transformation matrix of the identical 3D transformation.

Signature🔗

hom_mat3d_identity( out hom_mat3d HomMat3DIdentity )

void HHomMat3D::HHomMat3D( )

public HHomMat3D( )

void HHomMat3D::HomMat3dIdentity( )

void HHomMat3D.HomMat3dIdentity( )

Description🔗

hom_mat3d_identityHomMat3dIdentity generates the homogeneous transformation matrix HomMat3DIdentityhomMat3DIdentityhom_mat_3didentity describing the identical 3D transformation:

\[\begin{eqnarray*} \textrm{HomMat3DIdentity} = \mvHomMatrixThreeDElements{ 1 & 0 & 0 & 0 \\ 0 & 1 & 0 & 0 \\ 0 & 0 & 1 & 0} \end{eqnarray*}\]

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, HomMat3DIdentityhomMat3DIdentityhom_mat_3didentity is stored as the tuple [1,0,0,0,0,1,0,0,0,0,1,0].

Execution information🔗
