Sphere Subtraction

Sphere subtraction is a tiny GPU Boolean demo with a deliberately short tool tray: drag the cutting sphere, choose a 32, 48, or 96 resolution preset, apply the operation, and copy the result. It feels more like a geometry notebook than a modeling app.

What is Sphere Subtraction?

Boolean subtraction is the 3D equivalent of using one solid as a cookie cutter on another: the overlap disappears and a cavity remains. This page strips that idea down to a movable cutting sphere, three numbered resolution presets, an Apply action, and a Copy action. That narrow scope is the charm. There are no visible project menus or layers competing for attention, just one geometric operation presented as a compact experiment. The page does not identify its engine or explain what Copy returns, so treat it as a visual concept toy rather than a production tool.

What you can do there

• Drag a cutting sphere
• Choose low, medium, or high resolution
• Apply the subtraction
• Copy the result

Why we picked it

A single well-chosen interaction can be more memorable than a toolbox with fifty tabs. Moving the cutter makes an abstract modeling term easier to grasp, while the three resolution choices invite a quick comparison between speed and surface detail. It is a neat little bite of computational geometry with almost no ceremony.

How to get the most from it

Drag the cutting sphere into an interesting overlap, begin with Low (32), and press Apply to try the subtraction. Repeat at Medium (48) or High (96) to compare the result, then test Copy only after you have a shape worth keeping; the page does not explain the copied format.

Good to know

The page does not name a maker, engine, license, save format, or project history. Its source references Tiiny Host analytics and advertising scripts, and the host supplies the detected social image. Mobile behavior, keyboard access, screen-reader output, performance, privacy details, and the Copy action's output remain uncertain.
