OR, if there was a jit.gl slab shader that covers similar functions as the jit.gl.cornerpin object in respect to skewing the images ?

What i am looking to do is skew (by changing the corner positions) various image streams before merging them to one texture. The patch i am working on is based on the The Video Processing System Andrew Benson did, except the input has 4 video playback streams instead of two.

Cheers !!!!!!!!!!!!!

why not use jit.gl.node and jit.gl.cornerpin in conjunction? skew the image with cornerpin, and capture to texture with gl.node for compositing with the other images.

cheers Mr Ramierz, will give it a try ! :D

Hello,

I tried it out, where i used a gl.node object and sent it out to various Cornerpin objects, which meant i could keystone each video signal independently. Not sure if this is what you meant, as I am having a little bit of a hard grasping how the node object works conceptually (along with Videoplane, and rendering object) but at least its something. :)

The next problem i have is that after i have processed the image with Cornerpin , i need to get the signal back downstream as i have several over jit.gl.slab shades i would like to process the signal with. Is this possible ?

Thanks for all your help !

ps I noticed a bug on the Cornerpin WIKI page, where the max examples dont seem to be embedded correct;y on the website. FYI https://cycling74.com/wiki/index.php?title=jit.gl.cornerpin#jit.gl.cornerpin_Tutorials

THANKS, that really helped a lot ! Using the jit.gl.pix object to sum the signal really helped :)

I had to change the patch a little as i am in Max6 so for anybody interested i have pasted it here.

Once again thanks so much, i can now go and enjoy my Sunday evening in peace ! :D
