OVU
A downloadable drawing app for Windows, macOS, Linux, and Android
Ovu — Draw in 3D.
Ovu is a free 3D drawing app. You brush ink onto floors, walls and ceilings, and a single stroke can bend from one surface to the next without switching modes.
Official site: https://eld122.github.io/ovu/
Start on the floor. Keep dragging up the wall. Finish on the ceiling. One stroke, one undo, one continuous line.
What you can do
- Drag walls and snap them to the grid
- Scrub a full stroke-by-stroke timelapse of any drawing
- Drop portals between rooms
- Record and replay translucent “ghost” sessions
- Scatter 3D models along a stroke
- Draw live with friends in the same room via a simple link
Everything runs offline. No account, no server required for local work, no payment. Projects stay on your device and export as .glb whenever you want.
