TouchDesigner utilities pack

A set of TouchDesigner utilities and projects for audiovisual work, tested on Windows 11 and RTX 3090/3070.

• audio-mixer-fades: Trigger independent audio track fade in/out on button click, able to range, and master on/off (from 0-1).
• audio-play-callback: Custom callback on sample length of an Audio Play CHOP to allow logic when audio files stop playing (trigger a panel when audio finishes).
• dir-mapper-2d-slider: Creates a GLSL grid map from the number of files within an input directory, 2D Slider file navigator.
• dir-watcher: Populate a Table DAT with arbitrary directory (files with sizes and last-modified, also hidden).
• extensions: Template for abstractions (e.g.): op('xyz').myFunction() wrapped within a Container object with GUI visibility.
• feedback-blur: Fragment shader combining two input textures using additive blending with opacity control.
• feedback-shape-saver: Simple primitive shape color feedback with Movie File Out TOP export (composite on transparent background).
• get-running-apps: Populate Table DAT with running processes, PID, session name and memory usage (like task manager, hides CMD).
• glsl1-barrel: BarrelDistortion.frag shader on input video file, affects 4 corners.
• glsl2-pingpong: Ping-Pong Delay shader, feedback 0-1 (using .vs file).
• info-getter: A Text DAT execution on video file finish, creates a callback from video info channel.
• link-two-containers: A simple Select CHOP operator showing widget on container A triggered on container B (same logic as "send" and "receive" in MaxMSP).
• midi-to-vst: Simple boolean logic to send onNoteOn() and onNoteOff() to arbitrary VST3s.
• open-apps: Launch .exe applications found in provided paths, e.g. "C:\\Program Files (x86)", threaded search from string input.
• resolume-xml-parser: Parse a Resolume XML file with mapping values into a Table DAT (composition example with 2 layers).
• subprocess: Execute a request from a file on the same folder deriving paths (hides CMD using opened TD session).
• tcp-io: Simple server with TCP io between TouchDesigner session DAT and CMD (start tcp_server.py first).
• timer-subtitles-3d: Reads randomly generated sentences from a Table DAT, works on timer and displays with geometry to texture.
• venv-creator: Creates a separate venv\ (blocking), installs numpy and adds to sys, import numpy as np works then.
• video-mosaic-wall: Creates a 10x10 video mosaic in Geometry from Texture 3D.
• web-server-internal: Internal Web Server DAT with external communication such as tcp-io folder.
