3D content creation is usually done by commercial software like Maya and 3ds Max, or shareware like Blender. However, most of the current 3D modeling software tend to edit the content via 2D screen, which is not efficient and intuitive. In this work, we develop a virtual reality (VR) system, in which the user can not only create 3D content easily and smoothly but also collaborate with other users in the VR environment to accomplish their 3D design project. We use HTC VIVE to display the immersive designing environment and realize the interaction between the user and the 3D content. Through VIVE controllers, the users can perform painting, sculpturing, coloring, transformation, and multi-editor collaboration in the 3D virtual space. Compared with the traditional 3D modeling software, directly editing 3D content in the 3D VR environment is more user-friendly.
