problems using pd with 120 dpi
by Thomas Holzmann 29 Apr '10

29 Apr '10

Hello, I'm using the latest pd-extended and have display problems when using pd on a screen which is set to 120 dpi. Then most of the texts don't fit into the boxes. When I change the screen to 96 dpi everything works fine. I assume that's a problem with tk scaling!? Does someone know a solution for this? Thanks, Thomas

[PD-announce] Interaction Design Student Patches
by Freaky DNA 28 Apr '10

28 Apr '10

Greetings all, I have just posted a collection of student patches for an interaction design course I was teaching at Emily Carr University of Art and Design. I hope that the patches will be useful to people playing around with Pure Data in a learning environment, installation artwork and other uses. The link is: http://bit.ly/8OtDAq The patches include multi-area motion detection, colour tracking, live audio looping, live video looping, collision detection, real-time video effects, real-time audio effects, 3D object manipulation and more... Cheers, Leonard http://www.VideoGameAudio.com -------------- Pure Data Interaction Design Patches ------------------------------------ These are projects from the Emily Carr University of Art and Design DIVA 202 Interaction Design course for Spring 2010 term. All projects use Pure Data Extended and run on Mac OS X. They could likely be modified with small changes to run on other platforms as well. The focus was on education so the patches are sometimes "works in progress" technically but should be quite useful for others learning about PD and interaction design. NOTE: This page may move, please link from: http://www.VideoGameAudio.com for correct location. Instructor: Leonard J. Paul Students: Ben, Christine, Collin, Euginia, Gabriel K, Gabriel P, Gokce, Huan, Jing, Katy, Nasrin, Quinton, Tony and Sandy ---- GabrielK-AsteroidTracker - An entire game based on motion tracking. This is a simple arcade-style game in which the user must navigate the spaceship through a field of oncoming asteroids. The user controls the spaceship by moving a specifically coloured object in front of the camera. Features: Motion tracking, collision detection, texture mapping, real-time music synthesis, game logic GabrielP-DogHead - Maps your face from the webcam onto different dog's bodies in real-time with an interactive audio loop jammer. Fun! Features: Colour tracking, audio loop jammer, real-time webcam texture mapping Euginia-DanceMix - Live audio loop playback of four separate channels. Loop selection is random for first two channels and sequenced for last two channels. Slow volume muting of channels allows for crossfading. Tempo-based video crossfading. Features: Four channel live loop jammer (extended from Hardoff's ma4u patch), beat-based video cross-cutting Huan-CarDance - Rotates 3D object based on the audio output level so that it looks like it's dancing to the music. Features: 3D object display, 3d line synthesis, live audio looper Ben-VideoGameWiiMix - Randomly remixes classic video game footage and music together. Uses the wiimote to trigger new video by DarwiinRemote and OSC messages. Features: Wiimote control, OSC, tempo-based video crossmixing, music loop remixing and effects Christine-eMotionAudio - Mixes together video with recorded sounds and music depending on the amount of motion in the webcam. Intensity level of music increases and speed of video playback increases with more motion. Features: Adaptive music branching, motion blur, blob size motion detection, video mixing Collin-LouderCars - Videos of cars respond to audio input level. Features: Video switching, audio input level detection. Gokce-AVmixer - Live remixing of video and audio loops. Features: video remixing, live audio looper Jing-LadyGaga-ing - Remixes video from Lady Gaga's videos with video effects and music effects. Features: Video warping, video stuttering, live audio looper, audio effects KatyC_Bunnies - Triggers video and audio using multi-area motion detection. There are three areas on each side to control the video and audio loop selections. Video and audio loops are loaded from directories. Features: Multi-area motion detection, audio loop directory loader, video loop directory loader Nasrin-AnimationMixer - Hand animation videos are superimposed over the webcam image and chosen by multi-area motion sensing. Audio loop playback is randomly chosen with each new video. Features: Multi-area motion sensing, audio loop directory loader Quintons-AmericaRedux - Videos are remixed in response to live audio loop playback. Some audio effects are mirrored with corresponding video effects. Features: Real-time video effects, live audio looper Tony-MusicGame - A music game where the player needs to find how to piece together the music segments triggered by multi-area motion detection on a webcam. Features: Multi-area motion detection, audio loop directory loader Sandy-Exerciser - An exercise game where you move to the motions of the video above the webcam video. Stutter effects on video and live audio looper. Features: Video stutter effect, real-time webcam video effects _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

gem pipe?
by Andrew Faraday 28 Apr '10

28 Apr '10

Hey all I've recently tried to pass a gem chain through a [pipe] object (aiming to avoid multiple pipes going to translate and colour objects. However it seems the pipe object won't accept gemlists. Any ideas if there's an object that will do this? Thanks Andrew _________________________________________________________________ http://clk.atdmt.com/UKM/go/197222280/direct/01/ Do you have a story that started on Hotmail? Tell us now

Hello, I'm working over an object that is sequencing list items symmetrically over time, at some level we can randomize time lengths. it's attached and only needs [list-find]. I'm wondering if there is such list object and/or class object in pd patches repository? acw, patko

Problems Following Floss "Generating Waveforms" Article
by Alex Lucas 28 Apr '10

28 Apr '10

Hello, I've been trying to follow the examples given in the Floss manual for generating waveforms using an array. Unfortunately I'm having problems as when I generate a sinewave in this way I seem to be getting an unwanted clipping noise. The standard osc~ object sounds a lot smoother in comparison. I've attached a patch which compares the two waveforms. The Floss article can be found here http://en.flossmanuals.net/PureData/GeneratingWaveforms Any help with this would be very much appreciated, it may just be my soundcard acting strangely. Thanks, Alex
