I inadvertently did not have the crop patch referencing the original image size; this has been fixed in the download example. Hopefully those that downloaded this sussed this out.

The GLSL Vignette example in the dropbox here is a fairly commonly downloaded item. The code itself is something I probably picked up from the Orange Book or Clockwork Coders GL examples (?). The code is something I see pop up again and again, in all kinds of GLSL examples all over the internet; it's simply the way to make a Vignette, unquestioned. One thing that irks me about the method, is

"You Massive Clod", by Fearmoths, is pretty famous in the demoscene, and possible reason for that is that not only does it look cool, but the source is also available. Tigrou posted a version for Windows that contained the important shader code here: clod_win32 . I was looking at it today, and decided to replace the portion that's setting up the distance equations with what started as a torus.

The theme of this blog entry is something like "fragment shaders rock", mixed with some kind of weird conflict about it. :-) I read Iñigo Quilez's "Rendering Worlds with Two Triangles with raytracing on the GPU in 4096 bytes" not long after it came out, and was really fascinated with the principles that were outlined, but some of it was extremely far away from the type of programming I was doing

One thing I've found, through trial, error, gnashing of the teeth, etc., is that the QuartzComposer.app, leaks like a sieve.  There are *many* times (almost every?) that patch instances on the editor actually leak the contents, and few that they don't.  So, essentially, the editor is a tool for making the graphs/qtz's, but it's just not a great idea to use it for deployment. Furthermore,

I'm not going to spend the time to give a rundown of using Instruments.app; there are plenty of places that one can get instruction online, and the application is fairly straightforward to use. Instead, I wish to remind people how useful this can be, or give a head's up to people that aren't in the habit of using it. It is useful to be able to monitor for leaks while you're manipulating a

This looks super dull, but it's a little demo I made to show a non-Apple "interaction" system happening with ObjectKit. I'm generating objects with Kineme3D, and using the next (unpublished) version of ObjectKit to establish a structure of positions. The ObjectKit setup allows me to grab each individual Kineme3D object, and move them around by manipulating their positions through interaction

I've messed with this idea before, and it's basically related to the OpenCL particle stuff I posted a bit about last week or so. I'm trying to do it in a super low-rent, low particle count, ultra fast way, using just point sprites. The reason I'm doing that, is because I want to be able to have enough horsepower left over to run a decent blur kernel on the point sprites. It's just additive

I sat down tonight and did a couple of edge filters, riffing off of a Prewitt and a Sobel style sampling kernel. It's not really that far off from the same kind of logic involved in doing the core image normal map filters (the 2x2 and 3x3's I put together awhile back), but seeing p_g_'s edge filter the other day got me thinking about this more. I didn't do anything with the Sobel to do color

I recently had a chance to look at Matthias Oostrik's method of converting the 2D texture to particles, and Apple's "Snow" OpenCL example in depth. I looked at my "go-to" fluid simulation, and re-jiggered it to use some elements of those to generate particles from the textures I've generated. I'm not using any Optical Flow or Density type calcs from Oostrik's code, since that's already

I was trolling p_g's twitpics ( http://twitpic.com/6m3civ )and saw this interesting take on an edge detection. I thought it was aesthetically pleasing, so I took the time to copy it into the Core Image Filter patch, and save a .qtz version of it (in the Box widget). http://bit.ly/vb4zQw

If you're writing modern OpenGL, you know that tons of the built in matrix functions have been deprecated, and aren't available. It's not the worst thing in the world, because most of the math functions are well documented in multiple places, it's just a slight annoyance. I happened to notice ZIP, from Lighthouse3D, which has the file vsml.cpp that gives the math for most of the common gl matrix

I've been populating the Box dowload widget with A GREAT DEAL OF STUFF. More will come (as I've said.) If you're logged in with a Google ID, or I believe with Box.net (maybe?)

I've been digging through stuff that used to be in the downloads and populating. I've pushed more of the plugins back, and more sample files. More to come soon.

This is a link to a plugin that will spawn extra Viewer windows in Quartz Composer. The windows are resizable, and movable. It's a handy thing because it becomes easy to monitor the image output at multiple points in the chain, without divvying up stuff in the main viewer.It also seems to work with apps built in the QuartzBuilder compiler.http://www.climbapp.com/plugin/window/

I would be really remiss if i didn't point something out:Sometimes I do get really spectacular feedback on bugs, employees that "get" that you're really trying to help the OS be better, cover their butts/teams, and that if you're remotely busy (as an outside party), you need to just be able to relay info without a bunch of back and forth revolving around technicality.It is nothing but a pleasure

glClipPlane_gt from George Toledo on Vimeo.I've made a plugin for Quartz Composer that calls on GL Clip Planes 0~5, which is the count of six that is typically supported by OpenGL. This allows one to cull geometry in a scene by using eye coordinate values (the pitch, yaw, roll - sort of) to control 6 clipping planes. By default eye values (eg., patch defaults), no geometry gets culled.Using the

One of the cool things about the kinect is that the depth image is a really good source to use for edge detection / outline stuff, and it's easy to key out depth.This is sort of a reinvention of an old technique of mine ("g-body.qtz"), but using the kinect as a source, instead of regular video, and adding a number of other elements that set it up to work better, and work in Snow Leopard as well (

Some of the Apps that still may be available in the dl box, were made on Leopard 10.5 and used certain kinds of techniques that relied on what's called "window focus" to make them work correctly.

While reviewing the plugin project for the quad I posted about in my last entry, I noticed that it would be really easy to add in rotation for the object. All in all, it took my around five minutes.Having xyz translation and xyz rotation built into the object is handy to have because I tend to "shape" my Quad, then move it around via a 3D transform to place it where it needs to go.

A month or so ago I was delving heavily into fractals, mainly for one reason; content! By being able to generate scenes by pure math / OpenGL Shader code (or other shader code, like HLSL, Cg, OpenCL, etc., for that matter) and have a bunch of great, unique, fractals on the back burner, I ended up creating a big original library of fractal schemes that evoke different types of landscapes and

I've made a little "object detection" demo, that shows an approach to object detection based on storing texture offscreen.By looking up color values that are stored in a separate offscreen texture, one can use color detection to keep track of object id's. This uses primary colors, and is the simplest implementation.If one wanted to add more steps of complexity, one needs to test conditional for

I'm making a port of a GLSL routine to QC - an "advanced cartoon shader"- available in my Box downloads; "Advanced Cartoon Shader.qtz"/It does a kind of color averaging that gives a mellow cartoonized look, and also, by virtue of a skew horizontal/vertical routine working alongside the color routine, has the side effect of giving a kind of edge emphasis as well.

kinect liquid simulation from George Toledo on Vimeo.In demo-ing the kinect and programming some different looks, I came up with this particle system / liquid simulation.What I'm really liking about it is that I have a particle for every single pixel, and the physics reaction is happening swiftly in 3D space, being calculated off of a live video feed (the depth channel) and re-textured with

These are some screengrabs of some kind of abstract visual art that I'm creating in real time (so, as opposed to some kind of sequencing in where stuff is rendered "offline" later, this is limited to what the computer can eek out while you're manipulating the program in real time). I'm using Quartz Composer as my prototyping environment. The main components in pulling this off are an openCL

This uses OpenCL to do the fluid simulation and create a realtime normal map and color map, which is then rendered with GLSL shader and grid. Thanks to cwright for demonstrating how to do normal mapping in the GLSL shader, working around QC not supporting commonly seen methods.

Cubed from George Toledo on Vimeo.This is a piece I put together recently. I'll give brief rundown; excuse me if anything sounds "high falutin'".I wanted to write a piece in a type of rondeau form where the melodies would recapitulate, but over very different grooves, with some interesting transitions. The segments go something like "quiet storm r&b", to a kind of "I Can't Go For That" Hall and

I was recently reminded of some of the great work of Toneburst, and the many contributions he has made to the world of Quartz Composer. One of the most interesting aspects of Toneburst's work, has been his study of HLSL shaders, VVVV, and the porting of some great pieces to QC/GLSL. His GLSL and Core Image studies have been superb as well. His work is always tidy, well conceived, and visually

A personality trait that has affected my life is a passion to achieve lofty goals. No matter what I've been doing at a given time, I've always had a variety of goals that I'm heading for, oftentimes very statistically unlikely ones. GIven my background in Sociology, I tend to think of this kind of mental process as a natural outgrowth of survival instinct. The downside of this, is that in

A new iTunes version is out that has evoked all kinds of ire and whining from tech dweebs.While I can see why the new icon is aesthetically displeasing, I don't think the window control change to vertical is a bad thing.I'll give a few reasons why.Now, each function has it's own area, from left to right. Window controls don't have horizontal overlap. In addition, the new vertical window controls

Sex On Fire - Kings Of Leon - Remix from George Toledo on Vimeo.This is a remix combined with an accompanying visualization that I programmed.I've had a bit of a revitalized interest in remixes in the past weeks.

When I was working on example compositions for the Kineme Multitouch patch for Quartz Composer, I wanted standout composition, and I asked myself, "what describes Multitouch, visually"?By that, I mean, how could I create a realtime animation, that when photographed, or rendered, immediately conveyed to the reader that the graphic was created by touch.I went through different ideas, and I hit on

After looking at this article about bootleg iPads, and my personal experiences of having seen all varieties of bootleg iPods, I can't help but wonder, "why on earth would Apple get in bed with Samsung?"For those unaware, Samsung currently makes every A4 processor that Apple uses for their mobile devices. In fact, they are the largest producer of RAM and flash memory as well.Yeah, the same Samsung
