Google introduced Blocks, a tool for creating objects in virtual reality that can be shared with other users. The company claims that Blocks "is fairly simple and anyone can use it".
The application is similar to the children's constructor, in which items need to be collected from cubes. With this tool, you can create both simple objects and whole scenes in virtual reality. The created objects can be exported in the OBJ format for viewing in VR or AR, and the social features of Blocks allow you to get acquainted with the work of other users.
The tool is available for Oculus Rift owners in the Oculus Store and for HTC Vive on Steam.
