Re: [LAU] ShowQ - "a QLAB for Linux"

Hi, Apologies for tardy response - handling aftermath of a hard drive failure. :-\ On 14 May 2015 at 21:37, Michael Jarosch <riotsound(a)riotmusic.de> wrote: Praxis LIVE's audio pipeline has JACK support through JNAJack (which was originally written for it). There are a couple of things to bear in mind though - 1. Praxis LIVE is Java-based which *may* have an impact on latency (see 2) 2. It's not currently possible to play the audio from a video track. This is somewhat complicated by Praxis LIVE's distributed architecture, and the fact that audio and video may be in different processes or even running on different machines. Incidentally, one use for running audio in a separate process is reducing garbage-collection effects and improving latency. Not like Isadora v2 does. However, the recently released Praxis LIVE v2 does have full access to the 3D capabilities of the underlying Processing renderer. Coupled with the new custom code infrastructure and the ability to (re)write components on-the-fly this gives lots of possibilities for projection mapping and 3D transforms. There's a simple 3D quad transform component in the custom component repository already - https://github.com/praxis-live/pxg Expect to see more in the near future. There's a blog post on turning a Processing sketch into a Praxis LIVE component (here rendering a video onto a cylinder) - https://praxisintermedia.wordpress.com/2015/04/01/transform-a-processing-sk… Also coming soon is wrapping Processing's OBJ file loader. Bringing this vaguely back on-topic for this list - one of the reasons I haven't announced Praxis LIVE v2 here yet is I'm still finalising live code rewriting for audio components.
