TDLidar

TDLidar turns your iPhone into a live depth-sensing camera and a 40-sensor streaming hub for TouchDesigner, OBS, Resolume, and any NDI-aware tool on your network. Send LiDAR depth over the air, plus body and hand tracking, audio, motion, light, and dozens more sensors — straight to your show machine, no capture card or tether required.

Streaming the iPhone's depth into a live show used to mean cables, capture cards, drivers, and latency. TDLidar replaces all of that with a single tap: open the app, tap Start NDI, and your iPhone appears as a 1080p / 60 fps NDI source on every machine on the network — ready for 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. Every depth mode — Environment, Face Detail, Raw, Point Cloud — runs on both cameras. 15 colormaps, raw depth, topographic banding, posterisation, depth clipping, and live HD upscale. Every setting changes the stream instantly.

Sensors mode A full dashboard of ~40 on-device sensors. Enable the ones you need, preview each live, and stream them to TouchDesigner as clean OSC namespaces — ARKit body / hands / face, animal pose, QR / rectangle / text detection, saliency, scene classification, AR planes & mesh, 6DoF device pose, camera exposure, ambient & directional light, front/back distance, mic level, live audio FFT, on-device speech, sound ID, the full motion suite, AirPods head pose, Apple Watch heart rate, and NFC. Camera-based sensors also broadcast over NDI.

Point Cloud Streaming to TouchDesigner (Pro) Send a real point cloud — up to 50,000 points, bit-exact XYZ + RGB — into TouchDesigner POP geometry over a fast local connection. The matching TouchDesigner operator family is linked from inside the app.

Point Cloud Photos (Pro) Freeze the live LiDAR cloud into an interactive 3D "photo" and explore it from any angle — one finger to orbit, two to move, pinch to zoom. Tap the shutter to save a 3D model; hold it to record an orbit video. Re-open any capture, export to PLY for Blender or TouchDesigner, and save orbit videos to Photos.

Raw Mode in Colour (Pro) 15 depth colour maps, each painting the depth field and drawing its own topographic contour lines, with adjustable line thickness and a global colour grade.

Pro Features Point Cloud Photos, point-cloud streaming, raw topographic colour maps, HD upscale, extended LiDAR range, and the premium colormap pack.

WHO IT'S FOR

VJs running live visuals — a depth-aware camera and a sensor hub into Resolume or TouchDesigner in under a minute. Projection-mapping artists — drive masks and warps from real-world depth and motion, not a flat camera. AR / installation developers — prototype with ARKit body, face, and scene data 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, audio, and vision — nothing leaves your network. • Built for live performance — every setting can change mid-show without dropping the stream. • No accounts, no telemetry, no analytics. Camera, microphone and sensor data stay on the phone or your local network. Period.
