Archived Quartz Composer Files

As you may have guessed, I’ve not been doing much in the way of Quartz Composer-related work for quite some time.

I’ve been getting a few comments about the widget in the right sidebar of this blog not working. Sorry for not replying earlier. I’m realistically, not going to get time in the near future to look into the problem, so I thought it would be best just to bundle together all the content that used to be downloadable from the widget, and make the whole thing available via Dropbox. So, here it is. No guarantees of any sort that any of this stuff will work in more recent QC versions.


Superformula Offline Rendering

This is a really nice non-realtime rendering of a version of my Superformula Spreads QTZ, with added post-processing effects.

Great work George Toledo, and thanks for allowing me to post it here!

The offline rendering was done using Kineme’s excellent Quartz Crystal application, which opens up all kinds of possibilities for QC content-creation.


Nice Screenshots

Just rediscovered a really nice Flickr gallery featuring a modified pre-release version my Spherical Harmonics QTZ, and some lovely textures and font work.

Here’s a sample:
Spherical Harmonics example (by Scott Furr)

Nice work Scott Furr!

I included Scott’s modification in the release version of the qcClip, which is available here.

More info on the current release here.


Desaxismundi’s Velvet Shader

Desaxismundi was kind enough to let me see the code to his HLSL velvet surface shader. After a bit of fiddling around this morning, I was able to get it working in QC. Here is the result, applied to some imported 3D meshes, created with the Paul Bourke’s excellent supershape explorer application.

I’ve modified the code slightly, so it runs as two discrete functions, one in the Vertex Shader, and one in the Fragment Shader. You just have to call these functions from the main loop in the two shader programs. The VS function takes the normal as input and outputs the correct varyings to send to the FS, and the function in the Fragment Shader takes as input the various lighting parameters, and a texture input and returns the final lit colour of the fragment.

This should make it nice and easy to integrate into other shader code.


Isosurface Dances To Music on Vimeo

Just (finally) posted my first couple of video on Vimeo.

The first one’s just a test of the QC Movie Exporter plugin (which seems to work pretty well, shame there’s no audio), the second is the result of some initial experiments with the Isosurface raytracer, with parameters synced to audio levels in VDMX, and the virtual camera controlled by the SpaceNavigator.

Audio is ‘Mourning Gates’ by Hecq, from the album Bad Karma.

Archive of Quartz Composer FX for VDMX

Memo, of the rather splendidly-named Mega Super Awesome Visuals Company has very kindly setup an archive of qcFX compositions (Vidvox’s name for Quartz Composer compositions designed to work as realtime video effects within their VDMX5 application).

Lots of people have registered, so hopefully we’ll see the archive expanding in the near future, especially as people start to fiddle with the exciting now tools that came with the Leopard version of Quartz Composer (v3.0).

The archive is here. My efforts are the ones prefixed with ‘tb’.

There’s also a selection of qcFX on the VDMX Quartz Composer Wiki.
