Procedural Architecture

Authoring in TouchDesigner's Network Editor

  • visualize your data going through TouchDesigner networks with powerful interactive Viewers on all nodes
  • WYSIWID interface - what you see is what it's doing
  • zoomable user interface
  • mixed nodes - any combination of Operator types in a network - mix CHOPs with TOPs and SOPs, enabling tighter “in-the-zone” workflow
  • edit multiple Operators’ parameters simultaneously
  • drag-drop external files into network workspace including all media files and components (.tox files)

Image Manipulation and Compositing

  • resolutions up to 1280x1024 (unlimited in Pro version). mixed resolutions, adaptive animated resolutions
  • OpenCV and blob tracking
  • Cineform support
  • HD-SDI support

Modular Node Architecture: Components

  • Components hold a network of OPs, so you can encapsulate objects, scenes, effects, control panels and presets.
  • Components contain any combination of TOPs, CHOPs, SOPs, DATs objects, and materials
  • Components allow any combination of inputs and outputs - TOPs, CHOPs, etc.
  • Control Panel components
  • easy to share, easy to experiment - save out a Component to a .tox file for easy sharing with other users/projects
  • panel components can include a UI control panel or a full interactive 3D rendered scene
  • every component can have its own Timeline
  • Palettes of components are libraries of components from Derivative and user community - movie bins, image blender with 25+ blend modes, media player
  • easy to share, experiment with & re-purpose components (via .tox files)

Interface Design and Control Panels

  • control panels and custom user interfaces made with open-design Container, Slider, Button, Text Fields components
  • easy to access gadget states via Panel Values: momentary, toggle, radio buttons, drag out, UV, disabling, etc
  • fully programmable gadget logic and appearance - buttons are programmable, rollover triggering, flexible panel layouts
  • TUIK is a ready-to-use family of user interface gadgets prepared by Derivative - much of TouchDesigner's ser interface is made in TUIK
  • 3D interactive gadgets - Render Pick technology
  • use movies and motion graphics for UI gadgets
  • click, vclick, Multi-touch
  • TUIO
  • UIg

3D Surfaces and Geometry (SOPs)

  • imports 3D models and scenes via FBX from Maya, 3DS MAX, Houdini and others
  • polygons, meshes, NURBS, beziers, metaballs, subdivision surfaces
  • node-based procedural modeling (Academy-Award-winning SOPs)
  • GPU-based bone-weighted deformations for characters
  • L-Sytems
  • Metaballs
  • UV texture mapping methods
  • simple 3D modeler

3D Rendering

  • materials and shaders system (MATs) integrated with TOPs compositing engine
  • Phong super-shader material supports soft-edge cone lights, rim lights, fog, alpha blends and multi-layer textures, bumps, displacements, reflections, transparency, darkness, emission

CUDA - GPU Parallel Processing

  • TouchDesigner supports programs written for CUDA on GPUs, NVIDIA's parallel-computing environment

Procedural Scripting, Tables and String Arrays (DATs)

  • DATs – Data Operators can be used to hold any text data – raw ascii, scripts, etc or table data such as spreadsheets, csv files, etc.
  • DATs that execute short scripts when events happen in control panels, data flowing into TD, …
  • DATs are used for building UI, scripting, table management, variables, macros, HTML access, XML parsing, expression evaluation, ramps for the Ramp TOP and even for generating 3D in SOPs
  • concise scripting and expression language
  • scripts can be triggered by user interface events and internal/external states
  • tables as text arrays for managing large amounts of project data
  • unique procedurally-generated data tables reduce need for scripting
  • retrieve any HTML or XML via http:// addresses via Web DAT
