This engine takes as input a transformation matrix and a center of transformation. As output the engine produces the translation, rotation and scale values derived from the matrix.
The input fields can have multiple values, allowing the engine to decompose several matrices in parallel. One of the inputs may have more values than the other. In that case, the last value of the shorter input will be repeated as necessary.
SoMFMatrix matrix
The 4x4 transformation matrix.
SoMFVec3f center
The center of transformations.
(SoMFVec3f) translation
Derived translation in x, y, and z.
(SoMFRotation) rotation
Derived rotation.
(SoMFVec3f) scaleFactor
Derived scale values in x, y, and z.
(SoMFRotation) scaleOrientation
Derived rotational space for scaling.
