[PD] gem pix shear

[Py Fave]

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
