3D Geometry Animation

3D Geometry Animation is an open-source Android application in the Photo & Graphics category. It creates three-dimensional mathematical surfaces from user-defined formulas and displays them as interactive OpenGL animations. Surfaces can be defined as z(x, y), z(r, phi), r(theta, phi), or parametric x(u, v), y(u, v), z(u, v). The time variable t can be used to animate formulas, and several surfaces can be combined in one scene.

The app includes built-in examples such as waves, a pulsating sphere, a cylinder, and a Moebius strip. A custom math keyboard supports entering the formulas used to create surfaces. Users can store their own functions locally for later use. The interface also provides color selection, surface grid controls, rotation sensitivity settings, and graph orientation controls.

The application is designed for Android users who want to explore mathematical surfaces through an interactive graphical view. Its Photo & Graphics classification reflects its focus on rendering and manipulating visual geometric forms rather than serving as a general-purpose calculation tool. It does not request network access and does not include ads, analytics, tracking SDKs, account sign-in, or external API calls. User-defined functions and settings are stored on the device, although Android may include app data in system backup when that feature is enabled.

MirrorNest distributes the official build directly from its own storage. The mirrored build is scanned for malware before publication. This distribution setup gives Android users a locally hosted copy of the official application while retaining the software’s open-source status.
