PointShopVR: Immersive Authoring of Large Point Clouds in Virtual Reality

This paper presents PointShopVR, an immersive point cloud authoring system in Virtual Reality (VR) that enables intuitive creation, manipulation, and refinement of large 3D point clouds. To support real-time interaction with dense data, our system integrates a simple acceleration data structure and a continuous level-of-detail (CLOD) rendering, ensuring high frame rates in VR. PointShopVR provides a handful of authoring operations—including point addition, deletion, labeling, copy-paste, translation and deformation—each offering instant visual feedback for seamless editing. We evaluate PointShopVR through a user study in which users complete diverse editing tasks within minutes, demonstrating both the usability and effectiveness of immersive point cloud authoring. Compared to traditional desktop-based tools, PointShopVR offers enhanced accessibility, natural interaction, and immersive feedback, making it a powerful platform for large-scale 3D data exploration and creative editing in VR.
