Introduction

The general objective of the 3D Shape Retrieval Contest is to evaluate the effectiveness of 3D-shape retrieval algorithms. SHREC2020 is the fifteenth edition of the contest. Like previous years, it is organized in conjunction with the Eurographics 2020 Workshop on 3D Object Retrieval. At least one author per track must register for the workshop, and present the results. We also cordially invite all participants of a track to register and attend the workshop. . Thanks to the efforts of previous track organizers, SHREC already provides many resources to compare and evaluate 3D retrieval methods. For this year's contest, we aim to explore new and updated tracks. Therefore, the participants are invited to have an active role in the organization of the event. This includes proposing track themes, building or acquiring a test collection, and deciding upon the queries, relevance assessment, and performance measures. The participants of each track will collectively write a paper, which will be published in the proceedings of the Eurographics Workshop 3D Object Retrieval. At least one author per track must register for the workshop, and present the results. We also cordially invite all participants of a track to register and attend the workshop.
