PiVo OrthoBrowser low-poly 3D editor

Model, texture and animate low-poly scenes in your browser — local-first, with no account, no telemetry and no cloud.

Low-poly modeling

Cube, plane, pyramid, cylinder and triangular prism primitives with mesh/face/vertex picking, gizmo and numeric transforms, extrude/delete faces, mirror and merge.

Indexed texture painting

A fixed 128×128 indexed atlas with pen/eraser/fill/shapes, palette edits, gradients, shade ramps, PNG quantization and interactive UV handles.

Keyframe animation

Movement, rotation, scale, visibility and oscillation clips with drag-to-drop timeline lanes, adjustable snap, scrubbing and real scene preview playback.

Own format + open exports

Editable .pvo projects, OBJ/MTL/PNG and glTF/bin/PNG ZIP bundles, plus rendered PNG, animated GIF and sprite-sheet exports with retro effects.

Local-first & private

No accounts, telemetry, cloud uploads or runtime font/icon CDNs. A namespaced IndexedDB recovery copy protects unsaved work.

Recorded verification

The 10 October 2026 report records 320 unit/integration tests and 96 Chromium browser tests passing, including an independent Three.js glTF importer and a 50-mesh/2,100-face fixture. It predates the PWA addition.
