Vvvv Workshop

vvvv workshop conducted by joreg

vvvv is a:

1. hybrid development environment
2. visual programming language
3. node/code library
4. runtime environment

basic patching:

• new node - left doubleclick + start typing the nodename and select from upcoming list
• new iobox - right doubleclick
• nodelist
  • left doubleclick + rightclick to open an alphabetically sorted list of all available nodes
  • move mouse to the left to get the same list sorted by category
  • use scrollwheel to scroll this list. if you got no wheel hit space to *show a scrollbar
• connecting nodes
  • click on a pin to start a connection. notice that all pins that will accept this connection
  • have grown. click on such a bigger pin to establish the connection or right click to cancel

featured shortcuts:

• F1 - if a node is selected its corresponding help patch will be loaded. else. this patch.
• Ctrl+F1 - FanClub. the online source to get help via IRC-Chat
• Main Menu - middle mouse click on empty patch area (or right mouse click + space)
• Ctrl+P - create new patch
• Ctrl+O - open existing patch
• Ctrl+S - save patch
• Ctrl+I - create new inspektor
• Ctrl+W - close a window (deletes its corresponding node)
• Ctrl+Shift+W - close all windows and start all over again with a new root
• Alt+R - show root
• Alt+F4 - quit
• Ctrl+Shift+1 - take a snapshot of the window and get asked for a place to save the file
• Ctrl+Shift+2 - same as above. but only snapshot the clientarea of the window

component modes of windows:

• Alt+1 - show as window
• Alt+2 - show as box (in corresponding patch)
• Alt+3 - hide window
• Alt+Enter - fullscreen

• Press Ctrl-Tab to cycle through windows. to hide root, press alt-3

ways of viewing the renderer window / patch window

• docking
• fullscreen
• hidden
• in a box
• in a window

• Documentation on renderer - http://vvvv.org/documentation/renderer-(ex9)

exploring other patches

• http://vvvv.org/documentation/diki-patches
• use the inspector to see what types of nodes there are available - things such as iobox and framedelay....

Graphics

• quad = rectangle
• segment - polygon
• FileTexture - layers a file over

• VideoTexture with VideoIn - uses webcam image to texture the quad

• press ctrl-3 to upload it. no clue why it thinks im from china.

• FileStream (dshow9) to play video as the texture over (you can also use segment and fxfilters, such as LensDistort or Grain)

• Layer for effects, type mixer to see various effects...

• Translate, Rotate, Scale, Transform

• LFO - a popular function is the LFO - it will then change the values (eg if you connect the lfo output to the rotate z input then it will rotate continuously on the z axis
• LFO > WaveShaper > IOBox to use sine wave instead for smoothness
• Press F1 to see info on each node type
• Can use Tweener for easing effects
• if you do not have enough inlets (such as in the case of Group), you can click on the node, press ctrl-i to see the inspector, double click on the property and then type in the new number

Experiment: To make a sun with earth and moon rotating

• To neaten up the script, when you want to align the nodes vertically or horizontally, select the nodes in a row/column and press ctrl-l
