hom_mat2d_composeT_hom_mat2d_composehom_mat2d_composeHomMat2dComposeHomMat2dCompose (Operator)

Name

hom_mat2d_composeT_hom_mat2d_composehom_mat2d_composeHomMat2dComposeHomMat2dCompose — Multiply two homogeneous 2D transformation matrices.

Signature

Description

hom_mat2d_composehom_mat2d_composehom_mat2d_composeHomMat2dComposeHomMat2dCompose composes a new 2D transformation matrix by multiplying the two input matrices:

  HomMat2DComposeHomMat2DComposeHomMat2DComposeHomMat2DComposehomMat2DCompose = HomMat2DLeftHomMat2DLeftHomMat2DLeftHomMat2DLefthomMat2DLeft * HomMat2DRightHomMat2DRightHomMat2DRightHomMat2DRighthomMat2DRight

For example, if the two input matrices correspond to rigid transformations, i.e., to transformations consisting of a rotation and a translation, the resulting matrix is calculated as follows:

  HomMat2DComposeHomMat2DComposeHomMat2DComposeHomMat2DComposehomMat2DCompose  =  | R(l)  t(l) |  *  | R(r)  t(r) |
                      | 0  0   1   |     | 0  0   1   |

                   =  | R(l)*R(r)  R(l)*t(r)+t(l) |
                      |  0   0           1        |

Parallelization

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.

Parameters

Result

If the parameters are valid, the operator hom_mat2d_composehom_mat2d_composehom_mat2d_composeHomMat2dComposeHomMat2dCompose returns 2 (H_MSG_TRUE). If necessary, an exception is raised.
