An example of a realtime Sobel Edge Detection routine.
Also, a little pixellation effect to make it a little more interesting.

Sorry for the small screen but it's pretty intensive and requires two 3*3 masks to be applied to each pixel and calculations on the results.

Anyway, a Youtube video is coming for those who have difficulty running this.

There are a lot of selectable options you can use to see how different effects look with this filter, all totally interactive

Hope you enjoy it!

Btw: The binary is packed with UPX - if your AV software gives an alert, it's your AV software and not the intro!

I'll edit in the vid as soon as it's uploaded to Zootube..

Edit: [Video added]

Please note that the video is captured at 30fps - it looks better if you run the binaries..

Awesome demo! Lovely effects and it all runs really smooth!

Text was a bit hard to read at times.

Ah, cheers Kirl - I probably could have chosen a bigger font but I really love Frankie Ghost.. There's not much interesting text anyway I should make more of an effort next time!

It run so smooth on window and full screen!

Thanks Hotshot, glad you liked it and it ran smooth for you.

Runs super smooth for me.

Very nice Shockwave! Good work on all the different toggles too, lots to play with

Wow, this is indeed awesome stuff and just rules!

Music's nice too. Well done!

No problems running it on my computer, and that sobel effect is really nicely done. Also cool that you allowed for some interactivity.

Shockwave · « **Reply #8 on:** July 21, 2011 »

Thank you very much for the kind comments!

I'm pleased that it's running full frame rate for you so far

Makes me think I could have maybe pushed the resolution a bit higher...

Very well done mate

Hey, lots of stuff happening here, and very fast! I'm actually quite impressed with the raw speed of this.

Shockwave · « **Reply #11 on:** July 21, 2011 »

Thanks guys

It runs smooth even with my AV switched on

Still, I do like the range of effects, this time simultaneously. Excellent effort, and the tune is catchy.

The F-Key options are a plus too. Choosing a winner is going to be difficult again, but that's one of the things that makes these competitions worth entering.

I am really glad to hear that... There are over 20 calculations needed for each pixel in the Sobel area, I really did think that this was going to frame out on a lot of systems.

combatking0 · « **Reply #14 on:** July 22, 2011 »

From the looks of it, it works a lot faster than Flash.

Awesome work Shocky.

benny! · « **Reply #16 on:** July 22, 2011 »

Absolutely fantastic job there. I did not expect that a complete intro is the result of this competition really. But you
make a outstanding intro there. Very well done, mate!

Shockwave · « **Reply #17 on:** July 22, 2011 »

Thanks

I'm really glad you both liked it!

This is a very polished demo given the time that you had to work with.
I never really never cared for the Sobel filter until your demo!
Through adjusting the settings you can really see that there is not just one size fits all approach with such a filter I like that you have let us see the demo from different approaches.
I also like the pixely bottom filter it is pleasant and really makes you see how data can be crunched down with resolution. (I think it looks great)
The time spent to create different shapes and effects behind the square sobel filter is also noted, well done showcasing the effect on different subjects.

I'm jealous of the smooth tunnel alone, the rest of the effects are just rubbing it in my nose!

[edit] That seems weird, I believe that sould be: rubbing my nose in it...
