Download link, documentation and demo video are available at the link below.

I implemented his blur shaders (motion blur, zoom blur and fast blur) and they all seems to work fine but a lot of work has to be done before using them as solid generic effects. </div><div><a href="http://guidotamino.it/download/glslBlur.zip">http://guidotamino.it/download/glslBlur.zip</a></div><div><br></div><div>A couple months ago I opened a discussion with Cyrille on the theme but we were both too busy with work to fully dive into the subject. In the meanwhile I played around with the optical flow experiments by the jitter community with nice results, a demo could be seen here: </div><div><a href="http://vimeo.com/30517302">http://vimeo.com/30517302</a></div><div><br></div><div>I'm definetely interested in developing a set of glsl wrappers to make the whole thing easier for a beginner. I am a beginner myself and I had some tough times trying to figure out things like how to multipass glsl effects or how to feed multiple textures to a shader. This kind of stuff is almost undocumented and needs a lot of trial and error in order to be understood.</div><div><br></div><div>Best,</div><div>Guido</div><div><br></div><div><div>Il giorno 27/dic/2011, alle ore 11.22, philippe boisnard ha scritto:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; ">Hello<div><br></div><div>We have worked in codelab french forum about that since one month : </div><div>I give you the first test-lib that I have created : </div><div></div></div>
