Image Description, by
These are some frame-grabs from my fun-project called BeatHarness.
Basicly when going to (techno/trance) parties, I'm always staring at the VJ-screen thinking there could be
something more than 2 vcr's and a mix-deck :)
So I started working on my own 'automated' VJ-system (read: Winamp plugin :)), just for fun - and to show off the
videobeamer I've bought 1.5 year ago ;-)
For simplicity I've used Winamp as the framework that gives me the audio-data, but it wouldn't be hard to make it
a stand-alone app grabbing some sounds and performing some FFT's.
Since I didn't want to hardcode the effects, I've used AngelScript as
scripting-language to create the effects and transitions.
I can't ever thank Andreas Jonnson enough, without AS BeatHarness wouldn't exist !
Furthermore thanks to Vincent Klop for writing most of the scripts.
BeatHarness is completely script / content driven.
Features at the moment:
Effect scripts
Transition scripts
Image-textures, Video-textures (Avi, mpg, divx, whatever), Live camera input
feedback-grid-renderer ala Milkdrop / Geiss
enough draw-functions / renderstates / blendmodes that can be used from script - (textured) lines triangles,
quads, sprites, grids, alphablend, add, multiply(2x) etc.
Sound-info variables for the script : basic Bass / midtone / treble, and a GetFrequencyRangeIntensity(float
minFreq, float MaxFreq) function to get any freq-info you want.
Major ToDo 's :
Loading / rendering 3d-objects. Not that hard, but the script-interface has to be right the first time :)
(Once people have written scripts using it, I can't tell them I've totally changed the interface :))
Plugins (for the plugin :)) so people can code custom effects doing whatever they like with D3D that the script
doesn't. (Pixelshaders anyone ? :))
Once again, all this was actually pretty easy to implement using AS.
I'm going through the last beta-tests now, but I expect to have BH available for download when this hits
flipcode's IOTD :)
Just keep checking http://www.beatharness.com :)
Cheers,
Led
