Call for Workshops: CG Week 2021 - June 7-11, 2021

CG Week 2021 will be a virtual-only conference, June 7-11, 2021, anchored by the 37th International Symposium on Computational Geometry (SoCG). SoCG brings together a global community of researchers working on a large variety of topics that combine geometry, topology, algorithms, and applications.

To allow a broad audience to participate actively in the community's major scientific event, a series of half-day events will be organized throughout CG Week. Some of these events are workshops and minisymposia on topics related to all aspects of computational geometry and its applications.

Important Dates

  • • December 16, 2020: Intent-to-submit requested (not required)
  • • January 17, 2021: Workshop proposals due
  • • January 31, 2021: Notification of acceptance
  • • June 7-11, 2021: CG Week

Conference Web Page


Typical events feature some number of invited speakers and/or contributed talks. Note that we encourage organizers to consider posting an open call for contributed talks, in addition to having specific invited speakers, in order to broaden CGWeek participation and attendance. Workshop organizers are encouraged to start their workshop with a state-of-the-art report, accessible for the usual audience of CG Week, before featuring more specialized talks. Events may include other forms of presentations, such as software demos, panel discussions, industry forums, tutorials, posters, videos, implementation challenges, or artwork. Discussion among workshop participants is encouraged. CG Week workshops will have no formal proceedings. Optionally, the organizers may coordinate with journals to publish special issues, or arrange for other dissemination (via arXiv, webpages, or printed booklets, for example). We expect most events to last one morning or afternoon (3-4 hours), but some events may extend across two half-days.

Possible Topics

We invite proposals for events focusing on all topics of potential interest to the computational geometry community. Some possible topics include (in alphabetical order): algebraic methods, biology, cache-oblivious algorithms, chemistry, combinatorial geometry, computational photography, computational topology, computer graphics, computer vision, conformal geometry, differential geometry, folding/origami, games and puzzles, geographic information systems, geometric aspects of privacy, geometric software, geometry of graphs, geometry processing, high-dimensional geometric algorithms, implementation challenges, machine learning, manufacturing, massive data sets, mesh generation, motion planning, optimization, physical simulation, physics, real-world applications of CG, robotics, sensor networks, surface reconstruction, and visualization. For examples of previous CG Week workshops, please refer to the conference websites for 2012-2020, accessible from the Computational Geometry Pages.


We anticipate that CG Week workshops will be operated at low cost. In particular, CGWeek does not have a budget to support invited workshop speakers, and workshop speakers are expected to register for CGWeek. However, every workshop may apply to the CG Workshop chair (with final approval granted by local organizers), for one 1-day registration to be waived, provided they make a convincing argument that this benefit is essential to enable the corresponding person to attend. For example, this could be used to invite a local person who is not primarily in computational geometry or topology, and hence is unlikely to attend the rest of the conference. Moreover, workshop organizers may provide, from their own grants or from other sponsors, a budget for invited speakers. CG Week organizers will provide organizational assistance, including registration, meeting rooms at the CG Week venue, coffee breaks, wireless network, and a link to the web page of the event.

Submission Format

For planning purposes, prospective workshop organizers are requested (but not required) to notify the committee of their intent to submit a proposal by December 16, 2020.

Formal proposals should be submitted by email to the CG Week workshops chair,, by January 17, 2021. Proposals should be brief (at most 3 typeset pages) and should include the following information:

  • •Title or theme of the workshop/minisymposium/event
  • •Name and email address of the organizer(s)
  • •Brief scientific summary and discussion of the merits of the topic as it relates to computational geometry
  • •A description of the proposed format and agenda
  • •Proposed duration (both minimum and ideal)
  • •Procedures for selecting participants and presenters (which part of the workshop is dedicated to open submissions?)
  • •Intended audience (which part of the workshop is intended for the general CG Week audience, and which part is devoted to specialists?)
  • •Potential invited speakers/panelists (confirmed?)
  • •Budget issues (possible sponsors for invited speakers, if any)
  • •Plans for dissemination (such as journal special issues), if any
  • •Past experience of the organizer(s) relevant to the event
  • •The chance is high that CG Week 2021 will be an on-line only event. Please state your plans for in-person or fully virtual settings, with the possibility of in-person only or virtual only proposals. The decision whether CG Week 2021 will be in-person or virtual will be made at the end of January 2021.
