Flowiz

- Reads every format — .flo (Middlebury), KITTI 16-bit PNG, .pfm (Sintel), .npy/.npz, Spring .flo5, and PyTorch tensors — all through one fz.read. - Publication-quality color maps — Baker/Middlebury color wheel, bit-compatible (±1 LSB) with flow_vis; UV, magnitude and angle encodings; embedded color-wheel legend. - Temporally consistent video — sequence-wide normalization for flicker-free MP4/WebM/GIF, no ffmpeg install required. - Evaluation built in — per-pixel EPE, KITTI Fl-score, error-map heatmaps, and one-call compare_grid paper figures. - Vector overlays — quiver arrows on the color map or any background frame. - Fast & scriptable — vectorized colorization, multiprocess batch conversion, a flowiz CLI, and typed numpy-in/numpy-out APIs. - Browser viewer — drag-drop any flow file (or click a shipped example) at georgegach.github.io/flowiz; everything runs client-side. Drag flow files onto georgegach.github.io/flowiz — or click a built-in example (a real 5-frame sequence plus synthetic rotation/zoom/wave fields) — and inspect them per-pixel: u, v, magnitude and angle on hover, WebGL2 rendering, adjustable normalization, a color-wheel key in the side panel, PNG export, and movie playback of multi-frame sequences with a play/pause button and fps control. Everything runs client-side; your files never leave the machine. If flowiz helped your research or figures, a citation is appreciated (it's requested, not required — the MIT license asks nothing): Flowiz is the open-source project georgegach/flowiz (https://github.com/georgegach/flowiz) by georgegach, released under MIT. Ion packages it unmodified from commit e1e7a9cd3263, adding only a manifest, an icon and a storage compatibility script.

Not rated. Nobody has said who this app is suitable for, so Personal Clouds and the Oikou app treat it as 18+.

Internet

It asks to reach nothing on the internet.

Personal Cloud tools

• Keep a database of its own on your Personal Cloud ion.db
• Keep files in its own storage on your Personal Cloud ion.files

Notifications

It does not send push notifications.

Isolated pages

Runs its pages isolated (shared memory). Its pages get shared memory and precise timers, and load files from other sites only when those sites allow it.

Storage

Up to 1 GB on your Personal Cloud.
