Ontlus is a 4D sculpturing VR application that provides an intuitive way of creating dynamic 3D content and brings people in different places to collaborate together. We also develop a small object tracking system and mount it onto a real pen to simulate the nature way of drawing.
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 soft-ware 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.
