Hello qcdev,
OpenCL Sample Code Examples - Aurora - Music Visualizer Protocol ====================================================== This is all in relation to Aurora.qtz Creates a mesh from the Audio Spectrum data. Anyone else found that trying to create a structure from a queue of audio peak data really blows this little baby out of the water when iTunes is running? When she blows, she blows and I get the bad fluorescent bulb breakdown on my screen , sometimes followed by freeze ups. This is sometimes followed by a slow refreshing of System services, otherwise a total reboot is required :-(. Anyone actually got the Aurora bands patch [ a triplicate 3dTransform of twinned mesh renders ] working in iTunes? The Environment and Stars patches work AOK, and the composition rattles along fine in QC, but only reliably evidences non OpenCL within iTunes. A pity. Please find example items here AuroraAudio. They are slightly reworked versions of Aurora.qtz, a very interesting study example. Currently AuroraPeak works fully for me in ITunes , although I am wanting to up the Aurora Bands action, however, success was only achieved by means of queueing the Audio Peak data. AuroraSpectrum, however, doesn't produce / render a Mesh from the spectrum data. Although the spectrum data worked in the Viewer window in QC , it's a non starter for me in iTunes. I hasten to add that this is a non problem with other meshes that are not so dependent upon Audio spectrum data directly, even if they are partially fed by the data from that structure. It had to happen, as I typed this very message up, stepping lightly to avoid precipitating a crash, whilst listening to some tunes in the bg [with a spectrum dependent version of the the Aurora visualiser running in iTunes], I got this crash - long winded tailspin, from iTunes .
