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 (!)<span class="Apple-converted-space"> </span><br><br>Thanks a lot,<span class="Apple-converted-space"> </span><br><br>David<br><br><div><div style="margin: 0cm 0cm 0pt; padding: 0px; "><font size="3"><font face="Times New Roman"><a href="http://www.flickr.com/photos/schafferdavid/" target="_blank">http://www.flickr.com/photos/schafferdavid/</a></font></font></div><div style="margin: 0cm 0cm 0pt; padding: 0px; "><a href="https://soundcloud.com/schafferdavid"><font size="3" style="font-size: 12pt; "><font face="Times New Roman">https://soundcloud.com/schafferdavid</font></font></a></div></div></div></blockquote></div><br><div>
