12-parameter transform of JAG3D

Hi Micha,
There is a question about 12-parameter transform of "JAG3D".
Did you use 12 parameters = 3 translations and 3 rotations (rigid-body) + 3 shears and 3 zooms.
You can check attached pictures for understanding what I said.

And Can you tell me your Formula of 12-parameter in "JAG3D", if you can not, can you check below Formula(picture link) same as yours in in "JAG3D"?

Hi Darryl,

Did you use 12 parameters

Yes, a1...a9; tx, ty, tz.

$X = \begin{pmatrix} tx \\ ty \\ tz \end{pmatrix} + \begin{pmatrix} a_{1} & a_{2} & a_{3} \\ a_{4} & a_{5} & a_{6} \\ a_{7} & a_{8} & a_{9} \end{pmatrix} \cdot x$
