VSXu (VSX Ultra) is an OpenGL-based (hardware-accelerated), modular programming environment with its main purpose to visualize music and create real time graphic effects.

The aim is to bridge the gap between programmer and artist and enabling acreative and inspiring environment to work in for all parties involved.

VSXu is built on a modular plug-in-based architecture so anyone can extend it and or make visualization presets ("visuals" or "states").

How do i get it?

Compilation Instructions for a basic version of VSXu Ubuntu/Debian:

Make sure you have met the build dependencies:

  sudo apt-get install libglew-dev libpng-dev libjpeg-dev libpulse-dev libopenexr-dev libxrandr-dev libfreetype6-dev libsdl2-dev libegl1-mesa-dev libgles2-mesa-dev build-essential cmake

Optional dependencies:

  sudo apt-get install libopencv-dev

Get the VSXu Source from github via ssh:

  git clone [email protected]:vovoid/vsxu.git

Get the VSXu Source from github via https:

  git clone https://github.com/vovoid/vsxu.git

Build it:

  cd vsxu
  git submodule update --init
  mkdir build
  cd build
  cmake -DCMAKE_INSTALL_PREFIX=/usr ..
  make
  make install

vsxu's Issues

:20: in file names, linux64 version

Default visuals won't load due to this, from artiste's hypertree browser

Fix visualization file names for new naming standard

Go through all the .vsx files and rename them properly

(engine_graphics/src/vsx_statelist.cpp) Fix destructor

Currently the destructor of the class does nothing useful,
it should stop all the engines,
delete them.

The same goes for the faders.

With this in place, the app can simply delete vsx_manager when going to fullscreen mode.

Addition of querying capabilities to engine

For media players, one needs to be able to list and select a visual he/she wants to use....
Engine should be updated to add the querying capabilities.

Multi monitor support not working

add an executable parameter which quickly loads all non-loaded visuals

also requires updates to the statelist/manager

Documentation for Programmers

• messaging
• linkage

Make macros context zoomable

I.e. hide everything behind when you doubleclick

separate vsx_manager and statelist from engine_graphics into own lib

vsx_rand::frand memory read error in mersienne code

Split lib/ dir into own git project.

Keep only sources in that one, with the exception of fmod.

Fix GPLv2 headers in all files

See title.

luna size in artiste on windows is erratic

some keyboard double-event?

Integrate latest FTGL with VSXu

There has been several updates to FTGL.

See here: http://sourceforge.net/projects/ftgl/develop

We need to integrate the code again. I believe there was a few hacks needed, but not sure.

Fullscreen mode gives an error

"The reqquested Fullscreen mode is not supportet by Your Video Card"

FBO has issues with alpha-blending

you would get black when drawing 10 planes with color 1,1,1.0.1.
Solution: make alpha channel in FBO's optional.

"F1" on windows doesn't open help, but acts as "F"

Ensure VSXu Install paths should comply with GNUInstallDirs.

This line is causing a problem for those who install VSXu to */lib64 instead of lib
engine/src/core/vsx_engine.cpp: get_files_recursive(vsx_string(CMAKE_INSTALL_PREFIX)+"/lib/vsxu/plugins",&mfiles,".so","");

https://github.com/saidinesh5/tomahawk/blob/master/CMakeModules/GNUInstallDirs.cmake is a good start for this cleanup.

FBO doesn't work on intel cards

Create a Video Streamer Screen module.

Ideally the module should be able to stream VSXu render output over the network in an appropriate video format. This way one powerful server can stream to multiple thin clients.

An interesting addition for the module would be to support DLNA. Needs more research on how everything fits together.

trouble connecting the new connectors

When dragging out a new connector, check what is getting focus. It should not be the connector itself (I suspect this is the case) but rather the anchor where it's landing.

Go through and look at all warnings

There are a lot of warnings in the plugin builds.

glsl module doesn't find shader files

Implement nice looking connectors

bezier curves?

submit to debian

Debian:

• file a RTP and wait 2 weeks

If we want to create our own ppa, use using a version like 0-0ubuntu0~ppa1 to not mess up users packaging system.

Test with optimization compilation flags

Here's some interresting flags to test and see what happens:

http://www.debian-administration.org/article/Optimizing_code_via_compiler_flags

sequencer controller is not possible to close

Install VSXu headers, so that others can use libVSXu for their own application

We need to:

1. Install the header files
2. Appropriate Find_Package / pkg_config files

for engine and engine_graphics,

So that other programs can use libVSXu for their own development.

It should be noted that the current constructor of vsx_manager might have to be more friendlier: (how would a developer know where vsxu_visuals are installed??).

Code from VSXu Player:

  manager = manager_factory();
    std::string path = PLATFORM_SHARED_FILES_STLSTRING;
    // init manager with the shared path and sound input type.
    // manual sound injection: manager->init( path.c_str() , "media_player");
    #if PLATFORM_FAMILY == PLATFORM_FAMILY_WINDOWS
    manager->init( path.c_str(), "fmod");
    #else
      manager->init( path.c_str(), "pulseaudio");
    #endif

planeworld module does not output a mesh

Implement history popup chooser

When hitting Ctrl+doubleclick on a module input/output

Artiste - Crash upon double-clicking text in knob

When double-clicking the numbers in a knob, vsxu_artiste crashes with the error: Segmentation Fault.

Implement FFT from pulseaudio module into sound.mediaplayer

Implement graphics/module configuration store

Should be available for engine_graphics, modules. Maybe possible to pass some of these options to the engine in a constructor as well.

Android toolchain build

make macro background transparency variable

Implement a Midi input module using RtMidi.

RtMidi is a cross platform (OSX, Linux (Alsa and Jack), Windows) Midi API

http://www.music.mcgill.ca/~gary/rtmidi/

Figure out how to use Midi input from a module and implement it.

create helper HUD for new users

showing keyboard keys - sdfe to move around, w zoom in, r zoom out

these can be a bunch of PNGs fading in and out.

Fix .vsx file format to work on all architectures

.vsx files those are compiled in 32 bit dont work in 64 bit OSes. This needs to be looked into.
Issue priority: really high!

Fix regressions

A couple of regressions have been found. Use Luna to test these.

Investigate importing MMD models

engine crash when re-initializing sequenced parameters

To recreate:

1. create a GLSL loader with a uniform float input
2. add a sequence to this one
3. edit the GLSL code
4. save twice
5. program crashes; output from valgrind:

win32: server png not loaded in artiste

skybox thread join crash

If it doesn't complete its run it crashes on pthread_join.
Maybe it's due to not being a valid thread handle?

collision detection for connectors/anchors needs improvement

possible solution: make the ends of connectors (above anchors) not clickable when the anchor is "closed" ?

bitmap texgen segfaults on deletion

due to trying to join a non-created pthread

Add a help text when file not loaded in image loaders

Implement saving Visual FX levels in the registry

Currently this code is only written for GNU/Linux, so we'll need to implement it on windows as well.
In vsx_statelist.cpp

Artiste - Crash upon writing in empty console

When left clicking to open the console, it usually is alright. When you close it with right-click it's alright.
But if you do this a couple of times (doesn't seem to be a constant number, it happens on different numbers of tries), or just wait for the timer to stop (when the console is empty), you crash vsxu_artiste by writing something in it and pressing enter.
Results in Segmentation Fault.

Integrate latest LZMA with VSXu

http://www.7-zip.org/sdk.html

The compression has been improved a bit.

We need to look at backwards compatibility, how to solve that.
Possibly with adding a Version number for this new .vsx format. It's quite easy to check for that.

Additional navigation keys in artiste

arrow keys to move, pgup/pgdn to zoom.
