We analyze the input model using abstraction, simplification, and symmetrization operators to determine important features that are later represented by new geometry. Doing so, we create a stylized and expressive representation of the input that can be rendered or might be printed using a 3D printer. We conducted a user study to verify the proposed stylizations and demonstrate the approach by using standard geometry of buildings as well as natural and technical objects.","PeriodicalId":104077,"journal":{"name":"Proceedings of the Workshop on Computational Aesthetics","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123214697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These complex cyclic networks play an important role in understanding an ecosystem's dynamics. In this paper, we present a visualization layout inspired by Spirograph patterns, specifically designed for ecological networks. Our visualization supports both the direct and indirect quantities commonly required in ecological studies. The layout is circular to reflect the containment of the represented ecosystem and to clarify which connections are internal and which are external. In this layout, nodes are arranged along the circumference of a large circle as arcs, and edges are mapped to thorn-like shapes that represent the direction and the weight of the edge. Finally, we illustrate the use of this visualization on several example ecological networks.","PeriodicalId":104077,"journal":{"name":"Proceedings of the Workshop on Computational Aesthetics","volume":"415 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133913966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work we tackle the problem of simulating the process of observational drawing, that is, how people draw lines when sketching a given 3D model. We present a multi-phase drawing framework and the concept of sketching entropy, which provides a unified way to model stroke selection and ordering, both within and across phases. We demonstrate the proposed ideas for the sketching of organic objects and show a visually plausible simulation of their dynamic sketching process.","PeriodicalId":104077,"journal":{"name":"Proceedings of the Workshop on Computational Aesthetics","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131340359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We borrow concepts from information theory to develop some qualitative and quantitative measures, and use them to discuss four rendering styles which use Truchet-like tiles. We first present a style based on the original Truchet tiles, then we review the tile-based approach used by Inglis and Kaplan for Op Art rendering of 2-color maps, and extend the concept to 3- and 4-color input maps. We present two more concepts capable of rendering maps with up to 6 colors.

Boosting and enhancing colours are operations often performed for improving image aesthetics, but the relationship between colourfulness and aesthetics has not been thoroughly explored. By gathering perceptual data from a large-scale user study we have shown how existing colourfulness metrics relate to it and that there is no direct linear dependence between colourfulness and aesthetics but correlations arise for different image categories such as: \"landscape\", \"abstract\" or \"macro\".","PeriodicalId":104077,"journal":{"name":"Proceedings of the Workshop on Computational Aesthetics","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123792143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An effective information transfer of surface properties, encoded by textures, however, depends significantly on how important information is highlighted and cognitively processed by the user in an application context. Edge-preserving image filtering is a promising approach to address this concern while preserving global salient structures. Much research has focused on applying image filters in a post-process stage to foster an artistically stylized rendering, but these approaches are generally not able to preserve depth cues important for 3D visualization (e.g., texture gradient). To this end, filtering that processes texture data coherently with respect to linear perspective and spatial relationships is required. In this work, we present a system that enables to process textured 3D scenes with perspective coherence by arbitrary image filters. We propose decoupled deferred texturing with (1) caching strategies to interactively perform image filtering prior to texture mapping, and (2) for each mipmap level separately to enable a progressive level of abstraction. We demonstrate the potentials of our methods on several applications, including illustrative visualization, focus+context visualization, geometric detail removal, and depth of field. Our system supports frame-to-frame coherence, order-independent transparency, multitexturing, and content-based filtering.","PeriodicalId":104077,"journal":{"name":"Proceedings of the Workshop on Computational Aesthetics","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126801337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For example, Voronoi art uses a space-filling tessellation of the image by Voronoi cells. We present frayed cell diagrams as an aesthetic visual representation of the separating border between those space-filling regions. Our approach is based on a simple randomized algorithm that densely draws lines toward the reference points of cells. This algorithm is controlled by a few parameters whose effects are detailed in the paper: the density and size of cells, the degree of fraying, and the color coding. To demonstrate the usefulness of frayed diagrams for algorithmic art, we applied them to pieces of Voronoi art. Finally, we conducted a survey to assess the aesthetics of the frayed cell diagrams. As a result, we found out that the majority of the participants preferred a high degree of fraying, but that a non-negligible subgroup preferred diagrams without any fraying.","PeriodicalId":104077,"journal":{"name":"Proceedings of the Workshop on Computational Aesthetics","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121633292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
