At the start of each time step, we partition the waves into a bulk flow (which approximately satisfies the assumptions of the shallow water equations) and surface waves (which approximately satisfy the assumptions of Airy wave theory). We then solve the two wave regimes separately using appropriate state-of-the-art techniques, and re-combine the resulting wave velocities at the end of each step. This strategy leads to the first heightfield wave model capable of simulating complex interactions between both deep and shallow water effects, like the waves from a boat wake sloshing up onto a beach, or a dam break producing wave interference patterns and eddies. We also analyze the numerical dispersion created by our method and derive an exact correction factor for waves at a constant water depth, giving us a numerically perfect re-creation of theoretical water wave dispersion patterns.","lang":"eng"}],"intvolume":"        42","has_accepted_license":"1","file_date_updated":"2024-01-02T09:34:27Z","publication_status":"published","publication_identifier":{"eissn":["1557-7368"],"issn":["0730-0301"]},"title":"Generalizing shallow water simulations with dispersive surface waves","oa_version":"Published Version","day":"01","scopus_import":"1","author":[{"last_name":"Jeschke","id":"44D6411A-F248-11E8-B48F-1D18A9856A87","full_name":"Jeschke, Stefan","first_name":"Stefan"},{"first_name":"Christopher J","orcid":"0000-0001-6646-5546","id":"3C61F1D2-F248-11E8-B48F-1D18A9856A87","full_name":"Wojtan, Christopher J","last_name":"Wojtan"}],"date_created":"2023-08-27T22:01:17Z","article_type":"original","volume":42,"language":[{"iso":"eng"}],"oa":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"ama":"Jeschke S, Wojtan C.

This paper attempts to bridge this long-standing gap between complexity and performance, by proposing a new wave simulation method that can faithfully simulate wave interactions with moving obstacles in real time while simultaneously preserving minute details and accommodating very large simulation domains.\r\n\r\nPrevious methods for simulating 2D water waves directly compute the change in height of the water surface, a strategy which imposes limitations based on the CFL condition (fast moving waves require small time steps) and Nyquist's limit (small wave details require closely-spaced simulation variables). This paper proposes a novel wavelet transformation that discretizes the liquid motion in terms of amplitude-like functions that vary over space, frequency, and direction, effectively generalizing Fourier-based methods to handle local interactions. Because these new variables change much more slowly over space than the original water height function, our change of variables drastically reduces the limitations of the CFL condition and Nyquist limit, allowing us to simulate highly detailed water waves at very large visual resolutions. Our discretization is amenable to fast summation and easy to parallelize. We also present basic extensions like pre-computed wave paths and two-way solid fluid coupling. Finally, we argue that our discretization provides a convenient set of variables for artistic manipulation, which we illustrate with a novel wave-painting interface."}],"file_date_updated":"2020-07-14T12:44:45Z","publication_status":"published","month":"07","department":[{"_id":"ChWo"}],"file":[{"file_id":"5744","date_created":"2018-12-18T09:59:23Z","file_size":22185016,"date_updated":"2020-07-14T12:44:45Z","creator":"dernst","relation":"main_file","checksum":"db75ebabe2ec432bf41389e614d6ef62","file_name":"2018_ACM_Jeschke.pdf","content_type":"application/pdf","access_level":"open_access"}],"article_number":"94","oa":1,"language":[{"iso":"eng"}],"citation":{"ama":"Jeschke S, Skrivan T, Mueller Fischer M, Chentanez N, Macklin M, Wojtan C.

The placement of a shape is modeled as an oriented bounding box. Simple geometric relationships between this bounding box and nearby scene polygons define a feature set for the placement. The feature sets of all example placements are then used to learn a probabilistic model over all possible placements and scenes. With this model, we can generate a new set of placements with similar geometric relationships in any given scene. We introduce extensions that enable propagation and generation of shapes in 3D    scenes, as well as the application of a learned modeling session to large scenes without additional user interaction. These concepts allow us to generate complex scenes with thousands of objects with relatively little user interaction.","lang":"eng"}],"publication_status":"published","file_date_updated":"2020-07-14T12:45:07Z","month":"07","department":[{"_id":"ChWo"}],"article_number":"108","file":[{"file_id":"4647","date_created":"2018-12-12T10:07:49Z","file_size":11902290,"creator":"system","date_updated":"2020-07-14T12:45:07Z","relation":"main_file","checksum":"8b05a51e372c9b0b5af9a00098a9538b","file_name":"IST-2016-576-v1+1_guerrero-2015-lsp-paper.pdf","content_type":"application/pdf","access_level":"open_access"}],"oa":1,"language":[{"iso":"eng"}],"pubrep_id":"576","issue":"4","citation":{"chicago":"Guerrero, Paul, Stefan Jeschke, Michael Wimmer, and Peter Wonka. “Learning Shape Placements by Example,” Vol. 34.

The maxima of the resulting distribution are points with similar geometric relationships. We show extensions to handle mirror symmetries, and discuss the use of relationship functions as local coordinate systems.

Many real-world applications deal with very densely sampled point-cloud data, which are augmented with photographs that often reveal lighting variations and inaccuracies in registration. Consequently, the high-quality representation of the captured data, i.e., both point clouds and photographs together, is a challenging and time-consuming task. We propose a two-phase approach, in which the first (preprocessing) phase generates multiple overlapping surface patches and handles the problem of seamless texture generation locally for each patch. The second phase stitches these patches at render-time to produce a high-quality visualization of the data. As a result of the proposed localization of the global texturing problem, our algorithm is more than an order of magnitude faster than equivalent mesh-based texturing techniques. Furthermore, since our preprocessing phase requires only a minor fraction of the whole data set at once, we provide maximum flexibility when dealing with growing data sets."}],"file_date_updated":"2020-07-14T12:45:20Z","publication_status":"published","year":"2014","publist_id":"5189","status":"public","publication":"IEEE Transactions on Visualization and Computer Graphics","project":[{"grant_number":"P 24352-N23","name":"Deep Pictures: Creating Visual and Haptic Vector Images","call_identifier":"FWF","_id":"25357BD2-B435-11E9-9278-68D0E5697425"}],"date_published":"2014-09-09T00:00:00Z","acknowledgement":"This research was supported by the Austrian Research Promotion Agency (FFG) project REPLICATE (no. 835948), the EU FP7 project HARVEST4D (no. 323567).","doi":"10.1109/TVCG.2014.2312011","publisher":"IEEE","_id":"1906","date_updated":"2021-01-12T06:53:59Z","type":"journal_article","page":"1280 - 1292","ddc":["000"]},{"type":"journal_article","date_created":"2018-12-11T11:56:40Z","date_updated":"2021-01-12T06:56:25Z","volume":32,"_id":"2269","publisher":"Wiley-Blackwell","title":"Analytic Visibility on the GPU","author":[{"orcid":"0000-0002-1546-3265","first_name":"Thomas","last_name":"Auzinger","full_name":"Thomas Auzinger","id":"4718F954-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Michael","last_name":"Wimmer","full_name":"Wimmer, Michael"},{"first_name":"Stefan","id":"44D6411A-F248-11E8-B48F-1D18A9856A87","full_name":"Stefan Jeschke","last_name":"Jeschke"}],"doi":"DOI: 10.1111/cgf.12061","day":"06","publication_status":"published","quality_controlled":0,"intvolume":"        32","abstract":[{"lang":"eng","text":"This paper presents a parallel, implementation-friendly analytic visibility method for triangular meshes.

Recently, the acquisition of dynamic scenes at interactive frame rates has become feasible. A high-quality visualization of the resulting point cloud stream would require a per-frame reconstruction of object surfaces. Unfortunately, reconstruction computations are still too time-consuming to be applied interactively. In this paper we present a local surface reconstruction and visualization technique that provides interactive feedback for reasonably sized point clouds, while achieving high image quality. Our method is performed entirely on the GPU and in screen pace, exploiting the efficiency of the common rasterization pipeline. The approach is very general, as no assumption is made about point connectivity or sampling density. This naturally allows combining the outputs of multiple scanners in a single visualization, which is useful for many virtual and augmented reality applications.
