How to create some of those smooth organic effects-a la VJO?

mbira's picture

Hi folks, I recently moved over from PC, and I really miss the ease of creating simple flowing type effects in VJO. I haven't seen any quartz patches that do these simple type effects (though I'm sure they are out there and easy). Is there a library out there of these types of things that I can check out somewhere?

I'm attaching a few .movs from some VJO FX that I've made. Specifically, I'd like to find something like that "underwater looking up at light" effect, and things like simple "fog" and other "flowy" patches that I can use as effect layers to blend with media...

hmm-just viewed the video I uploaded-not sure what's up with all the flashy screen stuff on playback (at least on my system).

Works ok here.

Flowy stuff? Feedback, optical flow, both? God Rays? Post effect with a zoom blur and additive blend.

I think you will find the following tutorial to be what you want minus the water effects?

Having had a look at your clip I don't see flowing text effects, but I do see something like what this attached project does.

Maybe that'll help, think an OpenCL kernel, for producing turbulence, rendered above a renderer for the chosen video.

The project file contains the QC comp and the .mp3 file loaded.

The movie is derived from the Rollercoaster movie being called from its default installation point - /System/Library/Compositions/Rollercoaster.mov

Requires Kineme GL Tools

Requires Kineme Audio Tools

Requires OS X 10.6.x

60s.mp3 - original via Garageband Loops Mixing from cybero 2010

Rollercoaster movie - default install with OS X

Composition made available under Free Document Licence

This is a great tutorial! I really learned a lot here! Thanks!

@cybero-I don't understand what that patch is doing yet, but it sure is cool!

Pleased to hear it is working for you.

The 'trippy' graphical overlay is the product of porting the noise kernel OpenCL example to QC and asking it to write a frame by frame result out as an image stream - instant 'video' from an OpenCL kernel .

I've posted the beginnings of a more fulsome explanation here

thats cool you have your own free document lic. cybero. i usually choose the MIT lic here on kineme as its really the only option. do you think a gnu lic is better than a mit lic ?

the fluid light underwater effect is one of my favorites. i can remember in the 90's doing volumetric renders with bryce to create this effect. i have been meaning to address this topic with a patch. got to find it as i pull up over 100 patches when i search for fluid.

here is a recent fluid sim i made for the kinect you might be able to make use of. it is a mess requires some plugs as it originally was set to occlude 3d objects. i got to clean it up to add to the repo but you could modify it to give you a fluid light beam type of effect.

gt posted a screen saver the other day that uses accum to make some nice light streaks you should check out as well. once this is cleaned up i will post to the repo but you can play with it now if you like. here is a video capture of the effect. i would think this could be modified to be underwater.

also here is an underwater patch i made with leopard and k3d. im not sure its a bit flakey running in snow leopard. i usually have to try and run it a few times before it will render. i think it might have something to do with the glsl shader im not sure but it does run in SL. it just flakey as to when it wants to run it seems totally arbitrary as sometimes it will take 3-4 launches to run it for me now sometimes it runs first time ?maybe you could figure it why not sure. i really like the refraction shader as i find it integral to the effect but if it doesn't run after a few tries just disable the glsl shader.

here is screen shot of my underwater effect.

i don't really like to upload things that are kind of flakey but feel these to appropriate to your question on organic fluid comps.

no, but then I don't have much of an opinion, knee jerk , informed or otherwise upon the matter, neither.

nice example - powerful.qtz :-). Had to switch the kinect for a bog standard video input & give it a local .mp3 to chew over, still works quite nicely.

your underwater example, I think I've seen before, impressive, if I recall.

Still crashes out on the file path error previously reported [ easily corrected by re-associating the asset on a local file path :-)].

Check the attachment @

I checked it, it still works fine.

oh man is that is what is going on. could have swore I had a local file path. I thought I took out the audio file for powerful. should have posted the mp3. like I said I will post to the repo when I clean the file up

you did, I just jumped the gun, on further examination I can reproduce a total crash related directly on the report to the Kineme 3D plugin by opening BentUrchin.qtz, running the Viewer [successfully & sans crash ], then closing the Viewer, closing the Editor and reopening and reviewing - result, immediate crash , every time :-)

BTW, when the .fbx is replaced with a .dae, that problem goes away on the 3D Loader patch.

I really dig that rays-o-lite stuff. Here is a video of the logo I've been working on from that tutorial-attached lots of lfos to automate changes, etc.

Nice, it's cool to see you having a good time digging into QC.

One thing I've personally been kind of fixated on lately is using multiple layers with different "rayz o lite" coordinates. So, maybe some rays shoot up, while others shoot right. That can be a really cool twist on the theme. Coloring the different light ray billboards with different complimentary colors can be really interesting as well.

The above might be a little more involved than you want to get, but it's a good read and comes to mind because of the subject of "rays of light". It was informative to read about the occlusion method stuff, even without implementing what they're talking about from scratch.
