TouchDesigner is a visual programming environment developed by Derivative that allows users to create interactive multimedia experiences, including real-time 3D and 2D content, projection mapping, and live performance visuals. It’s known for its node-based interface, which enables users to build complex applications without traditional coding by connecting operators (nodes) that process and manipulate data.

​
Key Features

  • Real-time Capabilities:TouchDesigner excels at creating real-time interactive experiences, making it suitable for live performances, installations, and interactive media systems.
  • Node-Based Interface: The node-based system allows for flexibility and customization, enabling users to build intricate networks of operators to achieve desired effects.
  • Interoperability: TouchDesigner can integrate with various input devices, web connectivity, video and audio devices, and other software like Ableton, Max for Life, and Unity.
  • Projection Mapping: A key application of TouchDesigner is projection mapping, where content is mapped onto physical surfaces with precise control over multi-projector setups and ultra-resolution video.
  • Versatile Applications: It’s used in diverse fields, including art installations, live music visuals, architectural projections, and rapid prototyping.

​
How it Works

TouchDesigner empowers artists, designers, and programmers to bring their creative visions to life through a visual and highly customizable environment

​
Operators

TouchDesigner uses “operators” (nodes) that act as building blocks for your project.

​
Networks

These operators are connected in a network to create a flow of data and logic.

​
Data Flow

Data flows from one operator to another, with each operator performing a specific task (e.g., image processing, 3D rendering, data manipulation).

​
Output

The network culminates in an output, which could be a visual display, audio output, or data sent to another system.
