the glsl exemples are in a specific folder in gem/exemple. it's not very documented, but you'll have some basic shader. it's a good place to start. c

Hi, and thank you for your answers,
I know about extended view, I 've donwloaded it and used to build my design. The idea for me is now to get a better understanding of the glsl chain, because it seems to be the place where all the magic happens. I thought I could find more examples of glsl objects implementations in pd, and some written code that I could try to hack... any help appreciated.

ExtendedViewToolkit does photo stitching. Maybe it does what you want or can give you some ideas: http://puredata.info/Members/Weitsicht/extended-view-toolkit/

Hi there,
I'm in the process of writing my own photo stitching/assembling abstraction but I'm having a lot of trouble understanding what the glsl object do... I've been able to implement an edge blurring function by copy/pasting the glsl code from the "panoramique.pd" patch and the "panoramique.vert" and "panoramique.frag" files to the right places, but it only blurs vertical edges. Can anyone tell me how I could blur horizontal edges too? and... what this glsl thing is all about. I'm no code expert, so please keep it understandable (!)
Thanks a lot,
David
