3D Geometry Animation

about

description

Create 3D mathematical surfaces from formulas and view them as interactive OpenGL animations. Define surfaces as z(x, y), z(r, phi), r(theta, phi), or parametric x(u, v), y(u, v), z(u, v). Use the time variable t to animate formulas, combine multiple surfaces in one scene, and start from built-in examples such as waves, a pulsating sphere, a cylinder, and a Moebius strip. The app includes a custom math keyboard, local function storage, color selection, surface grid controls, rotation sensitivity settings, and graph orientation controls. Privacy and offline use: The app does not request network access. It does not include ads, analytics, tracking SDKs, account sign-in, or external API calls. User-defined functions and settings are stored on the device. If Android system backup is enabled on the device, app data may be included in that backup by the operating system.
