Sample Array from Float Curve

What It Does

Evaluates a float curve at multiple X positions and returns an array of the corresponding Y values. This allows you to generate sequences of values based on a curve's shape.

Inputs

Name	Description	Type	Required
curve	The float curve to sample	Float Curve	Yes
samplePoints	Array of X positions (0-1) to sample	List	Yes
precision	Number of decimal places for the results	Number	No

Outputs

Name	Description	Type
values	Array of Y values sampled from the curve	List

How to Use It

1. Drag the Sample Array from Float Curve node into your graph.

2. Connect a float curve to the "curve" input.

3. Connect an array of X positions (between 0 and 1) to the "samplePoints" input.

4. Optionally set the "precision" input to control decimal places (default is 2).

Sample Array from Float Curve Example

Tips

• All X values must be between 0 and 1, representing normalized positions along the curve.

• Higher precision values will give more accurate results but might be unnecessary for most design applications.

Use Cases

• Animation Keyframes: Generate multiple animation steps from a single easing curve.

• Data Visualization: Create smooth distributions of values based on a curve shape.

• Design Scales: Build graduated scales for spacing, sizing, or opacity based on a mathematical curve.
