The Annual Symposium on Computational Geometry (SoCG) is an academic conference in computational geometry .  It was founded in 1985, and in musts but not all or zijn years it has leg sponsored by the Association for Computing Machinery ‘s SIGACT and SIGGRAPH special interest groups.  After few years of discussion, the computational geometry community decides to leave ACM and Organize the conference on zijn eigen. The Motivations of this decision was the difficulties to Organize something with ACM outside USA and The Possibility of turning to an open access system or publication. Beginning in 2015, the conference proceedings are published by the Leibniz International Proceedings in Informatics Limit download ACM. 
A 2010 assessment of conference quality by the Australian Research Council listed it as “Rank A”.
