The input is a sequence of meshes without correspondences representing the liquid surface over time. Our method enables the efficient selection of consistent space-time parts of this animation, such as moving waves or droplets, which we call space-time features. Once selected, a feature can be copied, edited, or duplicated and then pasted back anywhere in space and time in the same or in another liquid animation sequence. Our method circumvents tedious user interactions by automatically computing the spatial and temporal ranges of the selected feature. We also provide space-time shape editing tools for non-uniform scaling, rotation, trajectory changes, and temporal editing to locally speed up or slow down motion. Using our tools, the user can edit and progressively refine any input simulation result, possibly using a library of precomputed space-time features extracted from other animations. In contrast to the trial-and-error loop usually required to edit animation results through the tuning of indirect simulation parameters, our method gives the user full control over the edited space-time behaviors. © 2016 Copyright held by the owner/author(s)."}],"ec_funded":1,"language":[{"iso":"eng"}],"publication_status":"published","project":[{"_id":"2533E772-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","grant_number":"638176","name":"Efficient Simulation of Natural Phenomena at Extremely Large Scales"}],"article_number":"2994261","title":"Space-time sculpting of liquid animation","author":[{"first_name":"Pierre","last_name":"Manteaux","full_name":"Manteaux, Pierre"},{"first_name":"Ulysse","last_name":"Vimont","full_name":"Vimont, Ulysse"},{"last_name":"Wojtan","full_name":"Wojtan, Christopher J","orcid":"0000-0001-6646-5546","first_name":"Christopher J","id":"3C61F1D2-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Rohmer","full_name":"Rohmer, Damien","first_name":"Damien"},{"first_name":"Marie","last_name":"Cani","full_name":"Cani, Marie"}],"publist_id":"6222","article_processing_charge":"No","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"short":"P.

In particular, one must implement special "non-reflecting" boundary conditions, which dissipate out-going waves as they exit the simulation. Unfortunately, the state of the art in non-reflecting boundary conditions (perfectly-matched layers, or PMLs) only permits trivially simple inflow/outflow conditions, so there is no reliable way to integrate a fluid simulation into a more complicated environment like a stormy ocean or a turbulent river. This paper introduces the first method for combining nonreflecting boundary conditions based on PMLs with inflow/outflow boundary conditions that vary arbitrarily throughout space and time. Our algorithm is a generalization of stateof- the-art mean-flow boundary conditions in the computational fluid dynamics literature, and it allows for seamless integration of a fluid simulation into much more complicated environments. Our method also opens the door for previously-unseen postprocess effects like retroactively changing the location of solid obstacles, and locally increasing the visual detail of a pre-existing simulation.","lang":"eng"}],"department":[{"_id":"ChWo"}],"file_date_updated":"2020-07-14T12:44:47Z","ddc":["000"],"date_updated":"2023-02-21T10:36:12Z","status":"public","pubrep_id":"631","type":"conference","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"conference":{"name":"ACM SIGGRAPH","end_date":"2016-07-28","location":"Anaheim, CA, USA","start_date":"2016-07-24"},"_id":"1363","doi":"10.1145/2897824.2925963","date_published":"2016-07-11T00:00:00Z","date_created":"2018-12-11T11:51:35Z","day":"11","has_accepted_license":"1","year":"2016","quality_controlled":"1","publisher":"ACM","oa":1,"acknowledgement":"We thank the IST Austria Visual Computing group for helpful feedback throughout the project.
