Isadora 2.5, new chapter for creativity server, 3D shaders

In the landscape of live visual tools, Isadora is something special. Despite being known mostly in certain circles – its name itself is a nod to the world of dance (Isadora Duncan) – it’s uniquely adept in those worlds. When it comes to mixing live visuals and interactivity with modern dance and theater, for instance, […]

VDMX Adds Wondrous Shader Features – And a Spec For Adding Them to Visual Tools

They’re a recent addition to popular OS X live visual app VDMX. But now is the perfect time to talk about the magic of shaders, generally. Standard “fragment shaders” are capable of performing feats of visual wonder as both generators and effects, using geometry and pixels. Written in GLSL, they are portable to any OpenGL-compliant […]

Across the Universe: Mind-Blowing AV Performance Makes Music a Spacey Trip

Turning music and sound into three-dimensional worlds often yields something that fields like a trip through space. But this feels like a real trip. Through pulsing, glowing starfields, “Versum”‘s audiovisual movements are brain-bendingly transformative. Artist Tarik Barri has created an integrated world of sound and image that makes the interface and the compositional realms seamless. […]

More Coding Fun on iPad, Android, Beyond: Play with GLSL's Magical OpenGL Goodness

Want to work on your coding chops, but get away from the slavery of your desk and your laptop? Want to stretch out on the couch – or the cramped confines of a bus or coach plane flight? (Hello, EasyJet!) We saw yesterday how you can work with your iPad and Processing, via Processing.js. Here’s […]

More WebGL Fun: Use Shaders in a Browser, Play a Game with Fireflies

If your WebGL appetite still wants more 3D goodness in your browser, here are two additional examples since last week’s story. Via Tiago, Shadertoy is an in-browser renderer that allows you to edit shader code in GLSL (the basic language of an OpenGL GPU) and render it in-browser. The only bad news is that this […]

Forward-Compatible Effects: Use FreeFrame Plugins in FreeFrameGL with fugWrapperGL

An information-dense twitter tip from Bigfug has notified us of some great news for those who love FreeFrameGL’s high performance mojo, but are sad about all their great FreeFrame Classic (yes, I just made that nomenclature up) effects gathering digital dust. fugWrapperGL is a plugin which allows you to use FreeFrame 1.0 plugins in FreeFrameGL […]

Video Tutorial: Get Max-y Jitter-y Goodness in Cell DNA, for Moshing Your Optical Flow

Add Max patch effects to DNA. from Livid Instruments on Vimeo. Yesterday, we saw some splashy video distortion techniques applied to real-time video. You know what that means: it’s time to use these in live performance. Liquidify Video, Live: Optical Flow GLSL Datamosh Technique Here’s one start.Peter Nyboer, Max whiz and Livid developer, has run […]

Liquidify Video, Live: Optical Flow GLSL Datamosh Technique

motion distortion 2 from andrew benson on Vimeo. Datamosh? (The “forbidden” but harmlessly meaningless word?) Video squishification? Mushy data? Call it what you will, but applying real-time distortion and displacement to video so that video textures become flowing layers of pixels looks absolutely beautiful. Andrew Benson of Cycling ‘74 has only just begun playing with […]

Pixel Bender: Accelerated Filter Goodness in CS4

Earlier this week, I talked about some of the consumer-oriented feature improvements in Adobe Creative Suite CS4. But the most interesting development from Adobe is actually more on the developer side. Pixel Bender is a new format for making GPU-accelerated (and CPU multi-threaded) filters, which means fast blends (with different blend modes) and special effects. […]
