#ThreeNodes.js

This is an attempt to make something like "vvvv" in javascript, html and webgl.

Live demo: http://idflood.github.com/ThreeNodes.js/

• modular
• creating a custom "node" must be as easy as possible
• should be possible to switch interface for live performance (selection of buttons/toggle)

• local timelines ?
• automatic layout of node graph
• grouping (multiple nodes in one, possibility to have multiple instances)
• ability to take a group, ungroup it, make some changes an regroup it so there are 2 slightly different group definitions (and maybe easier workflow, like 'make this a new group definition')
• some kind of library panel like in flash to manage images/fonts/groups...
• preloader (+preloader node so the preloader can be customized)
• maybe add processingjs.org as an alternative to three.js
• sound nodes (Audiolet for instance)
• server with possibility to login, save (public/private), browse, fork, +1, ... (a bit like audiotools)
• when server + grouping are completed, ability to share custom group of nodes (tags, public repository, ...)
• script nodes (js). Create input/outputs from parsing js vars or simply define a standard way of doing it, 1 return, inputs injected in an array. Be careful when sharing if there is a server with login...
• glsl nodes (vert/frag)
• make threenodes.js compatible with other programs (load/export vvvv file (or vvvv.js), meemoo, ...)
• publish to chrome webstore
• use most chrome apps features (offline, chromeless renderer, ...)
• use google drive api (save, load, simultaneous collaboration, ...)
• more three.js (and other) nodes...
• native app based on chrome like adobe/brackets with "permissive" settings to easily allow image loading (CORS), ...
• soundcloud node (or simply a way to put an url in the SoundInput node)
• flickr image node when they allow CORS, google drive, freesound.org, archive.org, ...
• possibility to enable/disable plugins so the nodes list is not filled with unnecessary things
• search in workspace nodes (quickly find a named node, search all 'time' inputs for instance, ...)
• drag and drop image/movies from desktop to threenodes
• "MIDI" timeline when sound generation is added (tempo, ...)
• music and sound start/finish/volume/... should be possible to handle in node and in timeline if needed (like after effects)
• curves in timeline like after effect
• websocket node with example of server/client in flash/processing/java/scala or other
• ability to run an instance of a saved workspace from command line (send email alert when some inputs have a certain value for instance)
• csv, xml, ... node parser (and possibly d3.js renderer, or others)
• MidiFileInput (and similar) when sound generation is done
• directly select/move/rotate/scale objects in the renderer like any 3d software (and selecting an object3d (or subclass) node should display a x/y/z axis in renderer window to allow move/rotate/scale)
• gui button/knob/slider/textfield/bang/toggle/select/... nodes
• key shortcuts + possibility to assign custom key bindings on toggle buttons, ... ?
• more flexible webgl renderer (image in node or fixed in corner)
• procedural texture (layers with multiply/add/color..., canvas image, effects, ...)
• more UI fun inspired by what other programs do (but stay in 2D and keep performance a priority)
• make it easy to add a theme (+ add a white version, and make the dark one nicer)
• record values while playing like it is done in music applications (automation)
• when sound synthesis is done, add drum machine, sequencer, reverb, ... nodes
• ability to change layout mode (vertical/horizontal/smaller nodes expanded on hover/...)
• menu to automatically arrange nodes (spring based solution or other)
• nice user & dev documentation
• export sequence of png (or video if possible) like a render in ae (time start/end, fps, resolution, ...)
• better "flow" highlight (when a node is selected, make the inputs and outputs nodes more visible (maybe optional))
• display some attribute directly in the node (sliders/textfields/..., add a checkbox in the attribute editor to enable this)
• display scaled down subchilds of nodes inside a group node. Seeing the global workspace it should be possible to have an insight of the complexity of different group nodes (maybe optional)
• different color of bullet for each field types (or more general classifications like number, string, vectors and others)
• when dragging from one field to another, highlight only real possible connections (not all inputs like it is now, but based on field type)
• ...

This will automatically compile coffescript files to javascript, sass to css and haml to html.

1. install node.js 0.6.x (http://nodejs.org/)
2. install npm (https://github.com/isaacs/npm)
3. install coffeescript (http://jashkenas.github.com/coffee-script/)
4. install jade globally: sudo npm install -g jade
5. cd in ThreeNodes
6. npm install -d

1. cd in ThreeNodes
2. node server.js
3. with firefox or chrome go to http://localhost:3000/
4. allow this site to create popups (for webglrender node)

1. cd in ThreeNodes
2. node server.js build
3. a new /dist should have been created

If there is an error when building see requirejs/r.js#157 (comment) This will be fixed with the next require.js release (2.0)

1. install docco and dependancies
2. docco src/scripts/threenodes/.coffee src/scripts/threenodes//*.coffee
3. cp docs/App.html docs/index.html

• It is recommended to always access ThreeNodes.js from http since chrome has a highly restrictive file access when using file://. (see http://code.google.com/p/chromium/issues/detail?id=40787)

First, create a webglrenderer node. Then add a scene and connect it to the "scene" of the webgl node. On the scene children you would connect a "merge" and to it a mesh. With that there should be a red cube showing in the renderer window.
