Abstract

Conventional interactive 3D tree modeling systems are generally based on 2D input devices, and it’s not convenient to generate desired 3D tree shape from 2D inputs due to the complexity of 3D tree structures. In this paper, we present a system for modeling trees interactively using a 3D gesture-based VR platform. The system contains a head-mounted display (HMD) and a 6-DOF motion controller for interaction. We propose an improved procedural modeling method to generate trees faster for VR platform. Using the 6-DOF motion controller, users can manipulate tree structures by a set of 3D interactive operations, including geometric editing using 3D gestures, sketching, brushing and silhouette-guided growth. Our interactions are more flexible and convenient than using traditional 2D input devices, e.g., we allow the user to simultaneously rotate and translate parts of a tree using a 3D gesture.
