The program committee judges submissions on five criteria, each of which can lead to rejection. If a submission passes all criteria, then it will be accepted: there is no competition against other submissions.
If a submission does not contain original research by the authors, or if there is good reason to believe this is the case, this is reason for rejection. We do not accept submissions which have already been accepted for publication elsewhere. However, we do explicitly allow submissions that are under review at another conference or journal (at the time of submission to EuroCG).
If the main / a major result of a submission is not correct, this is reason for rejection. If the correctness cannot be established and there is serious reason to believe it is not correct, this is also reason for rejection. However, if the correctness cannot be established but it can reasonably be expected that the results are correct, this is no reason for rejection: an acceptance at EuroCG is no correctness guarantee.
If a submission is written in a way that makes it unreadable, or it does not follow the submission guidelines as listed in the call for papers, this is reason for rejection.
If a submission is trivial, this is reason for rejection. However, there is no "minimum level" of technical depth required.
If a submission is out of scope, this is reason for rejection. However, we wish to be inclusive in our interpretation of scope, which includes but is not limited to the list of topics in the call for papers.
