Curve

A node that lets you use a 0-1 function, built by dragging points directly in the editor on the node, in two ways. The curve itself is the same single curve in both modes; only what you feed into its horizontal axis differs.

• Envelope (default) — when Trigger arrives, plays the curve from the start over Duration seconds and outputs to Value. Fires On Complete at the end
• Shaper — uses the In value directly as the curve’s horizontal axis and outputs the bent result. A non-linear version of Remap

Parameters:

• Duration default 1 second (internally floored at 0.0001 seconds)
• Loop — carries the amount that goes past the end over into the next cycle, so the period does not drift even if frames are dropped. On Complete fires on every cycle
• The initial curve is the two points (0,0)–(1,1). Interpolation is monotone cubic (Fritsch–Carlson), so it never goes outside 0-1 between points

In Shaper mode, In is clamped to 0-1, and Trigger / Duration / Loop are not used. If the input stops, the output stops too.
