1 lubyk lua libraries for live arts Gaspard Bucher (Buma)! artist, musician, coder

2 lubyk is not a framework

5 Why lubyk? Reuse code from project to project Accelerate development (live coding) Simple APIs Good documentation Stability (unit tests)

6 History! 2006 First prototype in Ruby Slow, inaccurate, rubato music 2008 Second pure C++ version, many threads, mutex. Lua scripting. Works when not crashing

7 2008 Home machine learning based movement recognition

8 History! 2006 First prototype in Ruby Slow, inaccurate, rubato music 2008 Second pure C++ version, many threads, mutex. Lua scripting. Works when not crashing 2011 Third version, pure lua, Qt GUI, multi-process, network distribution (mdns, zeromq, Msgpack).

9 2011 boats to nowhere

10 2011 All written in lua (dub made Qt bindings)

11 What was wrong? Did not scale well to larger projects Confusing interface Hard to work on different parts (shaders, physics, control, music integration, etc). Too complex, hard to share modules Complicated GUI takes too much dev time!!

12 less is more

13 History! 2006 First prototype in Ruby Slow, inaccurate, rubato music 2008 Second pure C++ version, many threads, mutex. Lua scripting. Works when not crashing 2011 Third version, pure lua, Qt GUI, multi-process, network distribution (mdns, zeromq, Msgpack) Fourth version, modules, tests, doc

21 Libraries using lut four lut lmidi lui media bt dub lens lug xml yaml osc lub

22 lens lut lmidi lui four media bt Scheduling Socket (TCP, UDP) Thread Timer FileWatch dub lens lug xml yaml osc lub

23 encode / decode four lut lmidi lui media bt dub lens lug xml yaml osc lub

24 Core graphic types four lut lmidi lui media bt dub lens lug xml yaml osc lub

26 media (video, image) four Native (AVFoundation) Fast, asynchronous Multi-threaded lut lmidi lui media bt dub lens lug xml yaml osc lub

27 OpenGL 4 lut lmidi lui four media bt Shaders Geometry Etc dub lens lug xml yaml osc lub

28 Native UI lut lmidi lui four media bt Provides OpenGL context Event loop integration with lens View (window/view) Mouse, keyboard dub lens lug xml yaml osc lub

29 midi four Midi in/out Virtual ports, real ports Note handling (off event) lut lmidi lui media bt dub lens lug xml yaml osc lub

30 C++ binding generator lut lmidi lui four media bt Advanced type management GC protection Fast callbacks from C Cast, operators, etc Customizable Uses doxygen dub lens lug xml yaml osc lub

31 Libraries using dub four lut lmidi lui media bt dub lens lug xml yaml osc lub

32 OS Support four lut lmidi lui media bt dub lens lug xml yaml osc lub

33 Windows alpha beta released four lut lmidi lui media bt dub lens lug xml yaml osc lub

34 Linux alpha beta released four lut lmidi lui media bt dub lens lug xml yaml osc lub

35 Mac OS X alpha beta released four media = 10.9 lut lmidi lui media bt dub lens lug xml yaml osc lub

36 Future plans Simple multi-machine, multi-process support (mdns + zmq + dropbox) Parameter support (per effect, per object, etc). Makes code reuse and adaptation easy. Eventually, use a simple web app for this. Exploration needed, ideas welcome!

37 Immediate plans Finish Linux port, start Windows port, for fun RPi Extract lug from four and optimize data transfers Fix old lubyk libraries mdns (Zeroconf plug&play network) zmq (ZeroMQ messaging library) box2d (2D physics) Parameter handling Workshops!
