Call for Workshops

Computational Geometry Week 2019 Portland, June 18–21, 2019

CG Week 2019 will take place June 18–21, 2019 in Portland, Oregon, anchored by the 35th 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.


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 2012–2018, accessible from the Computational Geometry Pages at


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 all workshop speakers are expected to register for CGWeek. However, 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, 2018. Formal proposals should be submitted by email to the CG Week workshops chair,, by January 16, 2019. Proposals should be brief (at most 3 typeset pages) and should include the following information: 1. Title or theme of the workshop/minisymposium/event 2. Name and email address of the organizer(s) 3. Brief scientific summary and discussion of the merits of the topic as it relates to computational geometry 4. A description of the proposed format and agenda 5. Proposed duration (both minimum and ideal) 6. Procedures for selecting participants and presenters (which part of the workshop dedicated to open submissions?) 7. Intended audience (which part of the workshop is intended for the general CG Week audience, and which part is devoted to specialists ?) 8. Potential invited speakers/panelists (confirmed?) 9. Budget issues (possible sponsors for invited speakers, if any) 10. Plans for dissemination (such as journal special issues), if any 11. Past experience of the organizer(s) relevant to the event
