Thanks for your help.

i would like to output a pix with this transformation,with image wrapping around ,
so shearXY is not very practical in my situation.

i would prefer to avoid using pix_snap too.

i need it to be quite fast, working on a live 25 fps 720*576(cropped to square) video feed.

any other otions?

would a GLSL shader do it ?

or this?

[pix dump]

something shifting a list
|

(pix set]


on my video card pix_coordinates works only on right angles .

any advice welcome!

Thanks

Py

hello  list

i'm trying to  slant (kind of shear xy) a pix

any advice on how to do this ?

i tried to use pix_coordinates , freeframe plugins, pdmtl (without luck .

Please check the image i joined.

it shows the kind of transformations i need.

then it should be recursive, but i keep it for later...
i hope the images makes sense.

it's missing the first state wich is 4 squares side by side

Thanks and have a nice end of we
