We initiate a pioneer study on 3D sketching and build a 3D sketching system which allows users to freely draw 3D sketches in the air and demonstrate its promising potentials in related applications such as collecting 3D sketch data and conducting 3D sketch-based 3D model retrieval.
Based on the 3D sketching system, we collect a 3D sketch dataset, build a 3D sketch-based 3D model retrieval benchmark, and organize this SHREC track on 3D sketch-based 3D shape retrieval based on the benchmark. We propose a novel 3D sketch-based 3D model retrieval algorithm CNN-SBR based on Convolutional Neural Networks (CNNs) and achieve the top first performance in the SHREC track.
We wish that the 3D sketching system, the 3D sketch-based 3D model retrieval benchmark, and the proposed 3D sketchi-based 3D model retrieval algorithm CNN-SBR will further promote sketch-based 3D shape retrieval and its applications.
