Rendering and Compositing

Realtime GPU-accelerated compositor TOPs, composite HD video at 30-60fps
Realtime rendering of 3D scenes, including multi-pass rendering abilities
Pixel format support for 8-bit color RGBA channels up to 32-bit floating point channels and HDR
User-programmable image operations with GLSL pixel and vertex shaders for custom materials and shaders
Support for 3D textures and 2D texture arrays and multi-layer textures
support for 10-bit color displays
Materials and shaders integrated with TOPs compositing engine
Multi-frame image blending, time-based image blending

WYSIWID (What You See Is What It's Doing) - Industry-defining interactive authoring environment lets you visualize your data as you work.
All nodes (Operators) include interactive viewers displaying the node's effect as data flows through it.
Modular networks (Components) make it easy to encapsulate work.
Share and reuse components freely between projects, create asset libraries.
Scalable architecture makes sure you never out grow TouchDesigner. High-performance engine scales with hardware.
Server-Client networks, Replicators, and Clones are just some of the tools available to help scale projects into large systems.
Project-proven stability with hundreds of thousands of nodes, thousands of channels, hundreds of movies, heavy 3D geometry data.
Performance analysis tools (CPU, GPU, memory) give detailed feedback for optimization and performance tuning.

Cineform codec decoding for the highest quality video at resolutions up to 4K (Pro)
Video inputs from multiple USB/Firewire cameras, webcams, and HD capture cards (Datapath, NVIDIA, Blackmagic)
Export to QuickTime movie formats (with audio), realtime encoding using H.264 (Commercial and Pro)
Outputs any combination of images to multiple displays
Simultaneous playback, mixing, and triggering of multiple audio and video sources
MIDI and OSC in and out

Animation Editor and Animation Component provide flexible keyframing and playback control
Time-Slicing technology improves realtime motion smoothness
Motion clip blending and sequencing system for full character/animation control (Pro)
Triggers, constraints, overrides, connect any control channel to any parameter

Build your own control panels in 2D and 3D
Use sliders, buttons, text fields, containers, 3D objects as your panel building blocks
Easy to access panel states; momentary, toggle, radio, UV-position, drag-out, rollover, etc
Full customization to panel appearance and logic
Ready-to-use UI gadgets included in the TUIK library, lets you build control panels using simply drag-n-drop

Import geometry and scenes using FBX file format from Maya, 3DS Max, Houdini and others
Node-based procedural modeling (using Academy-award-winning SOPs)
Support for polygons, meshes, NURBS, Beziers, subdivision surfaces
Integrated particle system with sprite rendering
Realtime GPU-based GLSL deformations and bone-weighted deformations for characters
Basic 3D modeler

Support for various communication protocols (TCPIP, UDP, UDT, OSC, MIDI, and more...)
C++ CHOP and C++ TOP let you create your own custom operators in TouchDesigner using C++
Serial support for communication with Arduino, GPIO, virtual serial ports, and other RS-232 enabled devices
Shared Memory access with other applications (like ARToolkit)
Import geometry from other 3D package using FBX format
Retrieve any HTML or XML via URL and procedurally parse, extract, and filter the data

Scripts can be triggered by logic states, user interaction, and a multitude of internal and external events
Tables as text arrays for managing large amounts of project data
Integrated text and scripts in DATs, no external files required
Unique procedurally-generated data tables reduce the need for scripting
Native support for programs written for CUDA on GPUs, NVIDIA's parallel-computing environment
