• RH dialog called the parameters dialog

• TOPS: Texture operators — images and pixel data
• CHOPS: channel operator: manipulate channels or sequences of numbers
• SOPS: Surface operators — polygons, spheres, etc. (models?)
• MATS: Material operators — shaders that you might apply to SOPS or other surfaces
• DATS: Data operators — hold strings, XML, Tables, etc.
• COMPS: components — have networks inside of them. Also UI components

• chopto DAT
• trail chop
• info DAT shows the names of the parameters

• Container has panel. Add UI elements and connect with top/bottom connectors
  • drag onto Panel CHOP to see info about all the UI elements
  • after connecting UI elements under Children tab choose how to align
• Text outputs text
• Window shows output of an operator in a separate window. This would be how to show the final product?
  • click and drag operator to show in window into Window Operator parameter

• moviefilein: use Cue Point to scrub thru a video
  • R-click to save image
• hsvadj is hue and saturation
• over: put input 1 over input 2
• composite: basic compositing (difference, screen, pinlight, subtract, etc.) with unlimited inputs. Has preview grid
  • in the palette menu choose tools → blend modes to see all the compositing possible.
    • in its parameter menu choose pulse to get a browser help page on this component (why pulse?)
  • fixed layer: where we get the resolution and aspect ratio
• matte: composites 1 input over another then create a matte effect using the 3rd input as the matte
  • you can use matte to switch between 2 images if you change the matte channel in the parameters dialog to luminance
  • use extend left and extend right to choose how the image pattern repeats in the matte channel
• tile: kaleidoscope effect
• transform: rotate, scale, repeat, etc.
• layout: layout multiple inputs into rows, columns, or grids
• switch: switch (or blend) between inputs
• select: reference a TOP from any other location:
• drag the TOP you wish to reference into the TOP parameter in the parameter window of switch
• it's sort of like a “send” and “receive” for Pd and that's all it does?

* threshold: highlight areas (white vs alpha) that are beyond a certain brightness

• Blur: preshrink reduces the resolution before the blur is applied
• LumaLevel: increase brightness of bright areas in image
• Feedback: set the target TOP by dragging the target top onto the feedback operator to create the reference
• moviefileout: create a movie, optionally with audio (using Movie Audio CHOP perhaps) and save the movie to a file

• Select: filter for a specific output. Example: look for DONE channel name coming out of timer chop.
• Audio Movie: plays audio of a movie file
  • drag moviefilein TOP onto this CHOP to get the audio of a specific movie
  • to actually get a movie with audio then connect moviefilein TOP to moviefileout TOP then drag Audio Movie CHOP onto moviefileout TOP

• Copy: Make a copy of the first input at the each of the vertices of the 2nd input
• Sweep: sweep the first input along the vertices of the 2nd input like a “paper fan”
  • has skin and twist feature
• Convert: convert object to polygon
• Facet: low poly look (?)

• Text: type in “hello world” for example
• Merge: combine multiple DAT tables
• Sort: sort table

• Wires: connections between the same family
• Links: references between operators of different or the same families
• Top and Bottom Connectors: for components to show hierarchy

• A: Toggle operator viewer active
• I: Zoom into component
• CTRL L-CLICK: Add multiple operators at the same time

1. Make Chop viewer active
2. Click on TOP to get parameter window
3. Get parameter you wish to change to show in parameter window
4. Using LMB Drag Chop (with viewer active) into the parameter in the parameter window
5. Choose CHOP Reference in the context menu

1. Click on DAT or TOP you wish to connect to to get parameter window
2. Get DAT parameter to show in parameter window
3. Using LMB Drag DAT into the DAT parameter in the parameter window. Does not need viewer active.

• click and drag one top onto another. Active window not necessary

• To see output of CHOP (single or multi value) R-click on output of CHOP and choose a chopto DAT to see as a table
  • optionally use the trail CHOP to see the history of values
• Collapsing a network: select all ops in the network, R-click and choose “collapse selected”
• File→Export Movie to save a video. Suggestion: turn realtime off to avoid glitches
• default files are in Program Files→Derivative→TouchDesignerVERSION→Samples→Map

• it works best to R click on CHOP output and choose CHOP execute
• Alternatively you can type the name of the CHOP operator in the CHOPS parameter in the CHOP execute DAT parameter window
• If you drag the CHOP with viewer active into the the CHOPS parameter in the DAT parameter window it will choose not just the CHOP operator but also the channel and you may not want the channel
• To write to an operator from CHOP execute reference it with op('NAME_OF_OPERATOR').par.NAME_OF_PARAMETER
  • get the name of the parameter by clicking on the + to the left of the parameter in the parameter window. Example: Text parameter in text component is called text

• Screen: add two images together without producing values above white

• NDI: video over IP. Can be used for local video sharing
  • NDI DAT shows in a table all courses and streams available
  • NDI out TOP sends an NDI stream
  • NDI in TOP receives NDI stream. Fill in the source name parameter
• Syphon (MacOS)/Spout (Windows): in and out TOPS share textures and images via shared memory on the same machine
• Video Stream Out: stream content over local network or internet. Send to YouTube or Twitch for example. Might be an easy way to send to VLC as well?

• me.time.frame: frame # sent by timeline at a given moment
