Working with Data
—interactive audiovisual narratives
In this course, students will build up an understanding of data and develop skills to work with data in an interactive audiovisual context with the software TouchDesigner.
During this 8 weeks period, we will learn the ontology of data. How to collect them, and how to work with existing data in an interactive audiovisual context with TouchDesigner.
The structure of this lesson will be a combination of both lectures and practical hands-on workshops.
Week 1: introduction
During the Frist 1st and 2nd weak students will able to understand data and build up knowledge of how to collect, store, sort, and inquire data in TouchDesigner. In the meantime also building up a critical approach to evaluate if the existing data set is ethical by asking 4 important questions:
Where did the data set collected?
Who collected the data?
And is the purpose of the collected data?
Is informed consent given when the data set was collected from people?
Week 2: basic visual network in touch designer and how to work with exiting data
Week 4: advance visual networks in TouchDesigner and how to work with API
We will mainly focus on practical workshops, building visual networks that interact with both existing data and real-time data using free API.
Week 5: Tutorials and individual support.

4. data visualization: information is beautiful

What is data
JSON, tabular data(csv), XML? What is an API?
Looking for specific kind of data, google stuff
But data could come in a variety of formats.
And here is a list of data format you might encounter:
CSV XML JSON TEXT PDF
Or on the web page
API?
CSV file
A CSV file typically stores tabular data (numbers and text) in plain text. CSV stands for Comma-separated values.
Basic visual networks in TouchDesigner
TouchDesigner is a node-based visual programming language for real-time interactive multimedia content. It's been used by artists, programmers, creative coders, and performers to create performances, installations, and fixed media works.
Interface and operators overview
1.The network, operators, and timeline
2.viewing options
3.viewer active tag
4.display tag
Operators!-- the basic building blocks:
1. TOP - Texture Operators handle all 2D image operations.
2. CHOP - Channel Operators are used for motion, audio, animation, and control signals.
3. SOP - Surface Operators are the native 3D objects of TouchDesigner responsible for 3D points, polygons, and other 3D "primitives"
4. MAT - Materials are used for applying materials and shaders to the 3D rendering pipeline.
5. DAT - Data Operators are for ASCII text as plain text, scripts, XML, and tables.
6. COMP - Components represent 3D objects, panel components, and other various operators. These components can house entire networks of other operators.
Simple networks
Starting with TOPs imagine they are raw materials and recipes for your visual networks. later we can link them together and experiment.
let’s first put down the TOPs below into the blank space.
1. ramp, Noise, movie file in, circle, text, video device in.
2. lookup, composite
3. transform, edge, displace
As you can see some of the TOPs give us a red error, let’s because they need at least one input. don’t worry we will deal with it later:-)
simple script:
absTime.seconds
