Can I use the generated blob as a CSS mask or background?

Yes! The exported SVG can be used as an inline ` `, a background image Data URI, or converted to a CSS `clip-path: path(...)`.

Understanding Your Results

Calculates smooth Catmull-Rom to cubic Bézier curve paths, renders real-time vector shapes with customizable color gradients, and exports clean SVG markup.

Practical Guidance & Next Steps

Using 5 to 7 anchor points with moderate distortion produces balanced, natural organic blobs suitable for background illustrations and avatar masks.

What is this?

A design tool that generates smooth, organic vector blob shapes using procedural cubic Bézier splines.

How does it work?

1. Adjust complexity (anchor point count) and fluid distortion contrast. 2. Pick gradient start and end colors or randomize the seed. 3. Copy the clean, resolution-independent SVG markup for your web application.

Why use it?

Replaces tedious manual Bézier pen-tool work with instant, infinitely variable procedural vector shapes.

Technical Scope & Calculation Limitations

Generates 2D closed cubic Bézier SVG paths. Paths can be embedded directly in HTML or used with CSS clip-path.

Frequently Asked Questions

The generator computes polar coordinates with pseudo-random offsets and converts them into a closed cubic Bézier spline loop using Catmull-Rom tangent smoothing.
