TDLidar turns your iPhone into a live depth-sensing camera for TouchDesigner, OBS, Resolume, and any NDI-aware tool on your network. Streaming the iPhone's TrueDepth or LiDAR signal into a live show used to mean cables, capture cards, custom drivers, and a lot of latency. TDLidar replaces all of that with a single tap. Open the app, tap Start NDI, and the iPhone shows up as a 1080p / 60fps NDI source on every machine on the same Wi-Fi or wired network — ready to drop into TouchDesigner, OBS, or any NDI receiver. WHAT YOU CAN DO NDI Depth Streaming Send the front TrueDepth or rear LiDAR feed over NDI in real time. 15 colormaps, raw depth mode, topographic banding, posterization, depth clipping, and live HD upscale. Every visual setting changes the stream immediately, so you can dial in the look from the iPhone while the receiving machine renders. OSC Tracking ARKit body, face, and hand tracking streamed as OSC bundles to TouchDesigner. Plus motion sensors (accelerometer, gyroscope, magnetometer, barometer, altitude), live audio analysis (FFT bands, levels, beat detection), and on-device speech transcription via SFSpeechRecognizer. All packaged into clean OSC namespaces with sensible defaults. Point Cloud Streaming (Pro) Send a real point cloud to TouchDesigner — either as a depth + RGB stream the receiver can reconstruct, or as direct OSC point data. Expand mode and Fixed Grid mode, with adjustable density, point size, viewer zoom, and per-axis flips. Pro Features HD upscale, extended LiDAR range, head overlay (front camera), point cloud streaming, point cloud OSC, raw mode customisation, and the premium colormap pack. Available as a yearly subscription or a one-time lifetime purchase. WHO IT'S FOR VJs running live visuals — get a depth-aware camera into Resolume in under a minute. Projection-mapping artists — drive masks and warps from real-world depth, not a flat camera. AR / installation developers — prototype with ARKit body and face tracking sent straight into a TouchDesigner patch, no Xcode project required. Streamers + content creators — depth alpha mattes for cleaner subject keying in OBS, no green screen. WHY IT WORKS • Real NDI® Advanced SDK — full bandwidth, low latency, no transcoding hop. • On-device speech and audio analysis — nothing leaves your network. • Built for live performance — every Pro setting can be changed mid-show without dropping the stream. • No accounts, no telemetry, no analytics. Camera and microphone data stay on the phone or on your local network. Period. REQUIREMENTS iPhone with front TrueDepth camera or rear LiDAR scanner. iOS 18.6 or later. A receiver running NDI Tools, TouchDesigner, OBS with the NDI plug-in, or any NDI-aware app on the same network. Download TDLidar, plug your iPhone into your show, and stop fighting your tools.
