hom_mat3d_composeT_hom_mat3d_composeHomMat3dComposeHomMat3dCompose (Operator)

Name

hom_mat3d_composeT_hom_mat3d_composeHomMat3dComposeHomMat3dCompose — Multiply two homogeneous 3D transformation matrices.

Signature

Description

hom_mat3d_composehom_mat3d_composeHomMat3dComposeHomMat3dComposeHomMat3dCompose composes a new 3D transformation matrix by multiplying the two input matrices:

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:

Attention

Note that homogeneous matrices are stored row-by-row as a tuple; the last row is usually not stored because it is identical for all homogeneous matrices that describe an affine transformation. For example, the homogeneous matrix is stored as the tuple [ra, rb, rc, td, re, rf, rg, th, ri, rj, rk, tl]. However, it is also possible to process full 4×4 matrices, which represent a projective 4D transformation.

Execution Information

• 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_mat3d_composehom_mat3d_composeHomMat3dComposeHomMat3dComposeHomMat3dCompose returns 2 (H_MSG_TRUE). If necessary, an exception is raised.
