Interactive curve editor + LFO for TouchDesigner 202.12370 ++. Draw custom envelopes and waveform shapes on an HTML Canvas UI, output as a CHOP driven by any timing source — LFO, beat, timeline, or external signal.
## What It Does
Forget Animation COMPs and keyframe editors. Drop the `.tox` into any project, draw the shape you want with bezier or linear control points, and the curve flows out as a CHOP ready to drive anything — envelopes, audio-reactive visuals, parameter automation, animated camera pulls.
- **HTML Canvas UI** inside TouchDesigner via WebRender TOP — full-res, system-fonted
- **Custom curve CHOP output** — 256-sample Script CHOP ready to wire into a Lookup CHOP
- **Per-point bezier / linear toggle** — click a control point to switch interpolation
- **13 built-in presets** — linear, sine, triangle, sawtooth, sawtooth reverse, square, ease in/out/in-out, exp attack/decay, S-curve, noise (random)
- **Save and recall** — save the current curve with a generated name, recall any saved preset
- **Speed slider** — leftmost position freezes the LFO (speed 0); logarithmic 0.01–20 Hz; BPM-sync mode (30–300 BPM)
- **Forward playback** — ramp 0→1 continuously
- **State persists** across re-init and `.toe` save/load
- **Replicable `.tox`** — drop copies into any project; each instance is fully isolated
## Install
**Requires TouchDesigner 2025+**
1. **[Download `CURVETOOL_FREE_v2.tox`](https://github.com/REMvisual/td-CurveTool/releases/latest)** from Releases
2. Drag it into your TouchDesigner project
3. The component self-initialises on load — nothing else to set up
## Wire the Output
The component exposes two Out CHOPs:
| Out | Content |
|---|---|
| `out1` | raw curve samples (from `curve_output`) |
| `out2` | LFO-modulated output — the curve sampled at the internal LFO's phase every frame |
Typical patterns:
- **Built-in LFO** — read `out2` and you're done.
- **Drive it yourself** — ignore the LFO, read `out1`, feed it into your own Lookup CHOP with your own timing source.
## Interaction
| Action | Result |
|---|---|
| **Double-click** empty area | Add a control point |
| **Click** a point (no drag) | Toggle bezier / linear for that segment |
| **Drag** a point | Move it (endpoints are x-locked) |
| **Right-click** a point | Delete it (minimum 2 points enforced) |
