Sample Float Curve

What It Does

Evaluates a float curve at a specific X value and returns the corresponding Y value. This node allows you to get a precise point along a curve for interpolation or animation.

Inputs

Name	Description	Type	Required
curve	The float curve to sample	Float Curve	Yes
x	The position along the curve (0-1) to sample	Number	No

Outputs

Name	Description	Type
y	The calculated value at the given position	Number

Sample Float Curve Example

How to Use It

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

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

3. Set the "x" value to a number between 0 and 1 (defaults to 0).

4. The node outputs the y-value at that position on the curve.

5. 

Tips

• The x value must be between 0 and 1, representing the normalized position along the curve.

• For easing functions, 0 typically represents the start and 1 represents the end of the animation.

• Sample Array from Float Curve: For sampling multiple points along a curve at once.

• Bezier Curve: For creating standard cubic bezier curves to sample.

Use Cases

• Animation Timing: Get precise intermediate values for smooth animations.

• Easing Functions: Apply custom easing to transitions between states.

• Interpolation: Calculate values between keyframes based on curved rather than linear progression.
