Very ashamed to post for this question…
I have a quad, and I would like position, scale and rotate other objects in the coordinates system defined by this quad (its borders being at -1 and 1 in x and y).
I found something (see the patch), but not really satisfying since rotation deforms objects.
And I would like to be able to know the position, scale and rotation in the initial system (the vvvv one).
I tried Inverse and different orders of the transformations, but I don’t get it. I also tried ParallelEpiped (Transform), Homography (Transform 2d), no more success.
Basic problem, but I searched for hours…
Could somebody help me ?
PS : subsidiary question, in 45beta24 how to write comments in patch ???
