Microsoft has been working on a major refresh of its Paint app for Windows, which introduces support for 3D objects, stickers, and other tools for creatives.

A video demonstration and tutorial for the new Paint, found by Twitter user WalkingCat, details a complete overhaul and new features to support 3D creation, sharing 3D designs with a community of artists, and stickers.

The new app is currently only available to invited alpha testers but it may get a wider showing at Microsoft's upcoming Windows 10 event on October 26, according to Windows enthusiast site Thurrot.com. Microsoft watchers expect the company will unveil an all-in-one Surface PC and a possible Surface keyboard and mouse.

The tutorial video shows new painting tools that support pen and touchscreen for editing and staging scenes, using blended 2D designs, stickers, and 3D objects, which can be swiveled or flipped to be viewed from different angles. The app also retains Paint's basic features that have been there for the past decade.

It's not clear yet whether Paint will be released as a standalone app or if it will be shipped with a Windows update.

According to The Verge's Microsoft sources, Microsoft is aiming the rumored all-in-one at creatives. A new Paint app would showcase how Microsoft's hardware and software improvements complement each other in Windows 10 and how a stylus and touch could be introduced to a desktop PC experience.

An all-in-one would also round out Microsoft's Surface hardware lineup, arriving almost exactly a year after it introduced its first laptop, the Surface Book. Microsoft is also expected to highlight devices from Windows OEMs and unveil gaming-related updates.
