As opposed to traditional Sketch Retrieval, our queries are drawn directly onto an example model. Using immersive virtual reality the user can express their query through a sketch that demonstrates the desired structure, color and texture. Unlike previous sketch-based retrieval methods, users remain immersed within the environment without relying on textual queries or 2D projections which can disconnect the user from the environment. We show how a convolutional neural network (CNN) can create multi-view representations of colored 3D sketches. Using such a descriptor representation, our system is able to rapidly retrieve models and in this way, we provide the user with an interactive method of navigating large object datasets. Through a preliminary user study we demonstrate that by using our VR 3D model retrieval system, users can perform quick and intuitive search. Using our system users can rapidly populate a virtual environment with specific models from a very large database, and thus the technique has the potential to be broadly applicable in immersive editing systems. date: 2018-08-24 date_type: published official_url: https://doi.org/10.1109/VR.2018.8446609 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1593476 lyricists_name: Giunchi, Daniele lyricists_name: James, Stuart lyricists_name: Steed, Anthony lyricists_id: DGIUN06 lyricists_id: SJAME46 lyricists_id: ASTEE91 actors_name: Giunchi, Daniele actors_id: DGIUN06 actors_role: owner full_text_status: public event_title: 2018 IEEE Conference on Virtual Reality and 3D User Interfaces (VR) event_location: Reutlingen, Germany event_dates: 18 March 2018 - 22 March 2018 citation: Giunchi, D; James, S; Steed, A; (2018) Model Retrieval by 3D Sketching in Immersive Virtual Reality.
