THE SYSTEM BEHIND THE SURFACE

Inside Bloom Sweep.

Bloom Sweep stacks rounded satin layers round a point just off the lower right of the frame, each a little smaller than the one behind it, so they show as nested crescents that open like the petals of a bloom. Each layer is barely domed with a rim that rolls under; a soft key light from the upper left sends a broad satin sheen round its rim, and a fine bright line runs along its edge. Where one layer lies on the next it lays a soft plum shade, so every layer reads as its own sheet. The rims ripple gently and the layers breathe one after another.

Bloom Sweep is authored satin layers with a fixed studio light, not a physical cloth or flower simulation, and it does not wrap your own images.

Layers

How many rounded layers are stacked in the bloom.

Spacing

How far apart the layers' rims sit.

Radius

The size of the back layer, in frame heights; the others follow it.

Centre

The point the layers are stacked round, across and down the frame; just off its lower right by default.

Color Looks preserve these settings. Open the editor for all 21 controls.

THE SURFACE IN CONTEXT

Made for a real interface.

Open a beauty, fragrance or lifestyle launch on a light ground: the bloom rises from the corner and leaves the upper left clear for the heading.

Bloom Sweep used behind an example interface — Illustrative layout, not a customer project. The image is a still preview of the selected Look.

An illustrative layout. Your content stays in HTML; the shader sets the atmosphere.

A FEW USEFUL DETAILS

Before you ship.

What this surface does, where it fits, and where it stops.

Five by default; Layers sets from one to seven. Spacing sets how far apart their rims sit and Radius the size of the bloom.

Yes. Center moves the point the layers are stacked round; by default it sits just off the lower right, leaving the upper left clear for copy.

It presses the layer it is over inward and tilts its sheen; Pointer press sets how far.
