Generating Wave Path Data
Use a sine function to calculate y-coordinates across a series of x-positions spanning the SVG width, then connect the points with smooth curve commands to create a continuous wave shape.
- Sample sine wave y-values across evenly spaced x-positions
- Connect points with smooth Bezier curves rather than straight lines
- Close the path along the bottom edge to create a fillable wave shape
Customizing Wave Parameters
Expose controls for wave amplitude, frequency, and phase offset so users can adjust the wave's height, number of crests, and horizontal shift, then regenerate the path data live as a section divider preview.
- Amplitude control adjusts wave height for subtle or dramatic effect
- Frequency control adjusts the number of wave crests across the width
- Phase offset shifts the wave horizontally for layered wave effects
Frequently Asked Questions
How do I make the wave fill the full section width responsively?
Use a viewBox with preserveAspectRatio='none' and percentage-based container sizing so the wave SVG stretches to fill its parent section at any width.
Can I layer multiple waves for a parallax effect?
Yes — generate two or three waves with different amplitude, frequency, and opacity values, stacking them as separate SVG layers to create a layered depth effect.
