1. Mass Movement #1

    from tgfrerer / Added

    A mass choreography of 1200+ toons, orchestrated by GLSL, performed in realtime on the GPU. Check out the HD version if you'd like to count the toons. Dance movements extracted from files found at http://ch.nicovideo.jp/article/ar15976 , in the mighty MikuMikuDance(geocities.jp/higuchuu4/index_e.htm) file format, with original VMD motion by @Yui-chan (?) Music: "Ain't We got Fun" – Benson Orchestra of Chicago, 1921, transfer from an original cylinder recording: http://archive.org/details/BensonOrchestraofChicago Inverse kinematics & MMD file parsing with help from Bullet Physics: http://bulletphysics.org/ , VPVL: github.com/hkrn/MMDAI and hexFiend: http://ridiculousfish.com/hexfiend/. Google翻訳ありがとうございます。(And thank you, Google Translate) 3D bone transformations are pre-calculated in C++, and their matrices pushed to an instanced vertex shader. There, the toons are fleshed out, morphed, and distributed in space. Although the app runs at 60+ fps throughout on my MacBook, Screenflow had serious trouble encoding the frames at a proper rate when approaching 2:19, which is why I used the excellent ofxTimeline (github.com/YCAMInterlab/ofxTimeline) by @obviousjim to render out jpeg sequences for the demo video. ofxTimeline also helped switching & tweening the camera motion matrices using a customised timeline. Let's make this interactive! Made with openFrameworks.

      A real-time particle system, with 16384 boxes forming a force field. A typographic pulse shoots little blocks into space, like an abstract fountain. Part of the 'Box Set' series of sketches, of which one (https://vimeo.com/50990212) comes with open source. HD is better. Music: http://archive.org/details/BlueDanubeWaltz Made with openFrameworks – and congrats to the oF team for the release of 0072!

        I know. But I really needed that, now.

          A stable feedback loop within the boxes! reaction-diffusion system. Look at the FBOs to see how force and length oscillate over time. See also the boxes! sketch. (http://vimeo.com/50841645) Find the source code here: http://poniesandlight.co.uk/code/ofxVboMeshInstanced This builds on the openFrameworks flatshading tutorial found here: http://poniesandlight.co.uk/notes/flat_shading_on_osx/

                  A real-time cubemap modifier / generator using GLSL shaders. Takes a panoramic image and allows for rotations and adaptions before saving out cube map surfaces. Thanks to Paul Bourke (http://paulbourke.net/) for being so generous in sharing his mathematical knowledge. Made with openFrameworks.
