3D Geometry Animation1.5.0

Enter a mathematical formula and watch it become an interactive, rotating 3D surface rendered with OpenGL. 3D Geometry Animation works offline, turning equations into visual scenes that help learners, educators, and mathematics enthusiasts examine shape and motion directly. It accepts surfaces expressed as z(x, y), z(r, phi), r(theta, phi), or parametric equations for x(u, v), y(u, v), and z(u, v).

Use the time variable t to animate changing formulas, and combine several surfaces in the same scene. Ready-made examples include waves, a pulsating sphere, a cylinder, and a Möbius strip, while a dedicated mathematical keyboard makes custom function entry practical. Users can save their own functions on the device, choose surface colors, adjust grid display, change rotation sensitivity, and select graph orientation.

The app suits classroom demonstrations, independent exploration, and visual experiments with geometric forms rather than general-purpose numerical calculation. Local settings and saved functions remain on the device, although Android can include app data in system backup when that feature is enabled. It does not request network access and contains no advertising, analytics, tracking SDKs, account sign-in, or external API calls.

This open-source Photo & Graphics software runs on Android 8.0 or later for arm64-v8a, armeabi-v7a, x86_64, and x86 devices. Version 1.5.0 adds a Free graph-orientation option and an animation-time reset button, fixes the function editor after screen rotation, adds a monochrome launcher icon for themed Android icons, and updates the target SDK to 37.
