Detailed Description

Note: a matrix decomposition depends on the choice of center. So a "center" input is provided (with default value 0,0,0) and there is no "center" output.

Decomposes transformation matrices into values for translation, rotation, and scale.

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.
