“…It is thus essential to understand the state of the art of the field. Several surveys have already summarized the research for sub‐domains of visualization including flow visualization [BCP*12] and the visualization of brain connectivity [Ise15], provided a general tutorial [VGH*05], as well as recently reflected in general on abstraction [VI18]. In this state‐of‐the‐art report, we instead focus specifically on the rendering part for visualization of surface‐based data as it results, for example, from iso‐suface extraction (e.g.…”

In this paper, we survey illustrative rendering techniques for 3D surface models. We first discuss the field of illustrative visualization in general and provide a new definition for this sub‐area of visualization. For the remainder of the survey, we then focus on surface‐based models. We start by briefly summarizing the differential geometry fundamental to many approaches and discuss additional general requirements for the underlying models and the methods' implementations. We then provide an overview of low‐level illustrative rendering techniques including sparse lines, stippling and hatching, and illustrative shading, connecting each of them to practical examples of visualization applications. We also mention evaluation approaches and list various application fields, before we close with a discussion of the state of the art and future work.

“…Visual abstraction: The visual abstraction of spatial data is a core concept of illustrative visualization [VI18] that has been applied in numerous domains. † For example, the schematization of network data such as streets has been studied in detail, both for traditional geography applications [CdBvK05] and for artistic purposes [Ise13].…”

Figure 1: A nanotube transitions from a 3D shape model to a diagrammatic 2D representation and finally to a clean 1D alignment of single strands. Orthogonal to the dimension axis is the scale axis, which shows different semantic scales. The orange rectangle tracks a single strand through the dimensions and scales. AbstractWe present a novel visualization concept for DNA origami structures that integrates a multitude of representations into a Dimension and Scale Unifying Map (DimSUM). This novel abstraction map provides means to analyze, smoothly transition between, and interact with many visual representations of the DNA origami structures in an effective way that was not possible before. DNA origami structures are nanoscale objects, which are challenging to model in silico. In our holistic approach we seamlessly combine three-dimensional realistic shape models, two-dimensional diagrammatic representations, and ordered alignments in one-dimensional arrangements, with semantic transitions across many scales. To navigate through this large, two-dimensional abstraction map we highlight locations that users frequently visit for certain tasks and datasets. Particularly interesting viewpoints can be explicitly saved to optimize the workflow. We have developed DimSUM together with domain scientists specialized in DNA nanotechnology. In the paper we discuss our design decisions for both the visualization and the interaction techniques. We demonstrate two practical use cases in which our approach increases the specialists' understanding and improves their effectiveness in the analysis. Finally, we discuss the implications of our concept for the use of controlled abstraction in visualization in general.

“…These aspects have been discussed in the visualization and expressive rendering literature, such as in the contributions by Rautek et al [2008] and Viola and Isenberg [2018]. Here, abstraction is "a transformation which preserves one or more key concepts and removes detail that can be attributed to natural variation, noise, or other aspects that one intentionally wants to disregard from consideration" [Viola and Isenberg 2018]-to allow viewers of a visualization to focus on major or important aspects. In this work, however, we explore the abstracting qualities of image filters for the removal of details such that the images are perceived as less offensive-potentially because they no longer depict surgery situations in all their details.…”

Original photo of a lasagna dish.Output of HueShift2. Output of FlowAbs [Kyprianidis and Döllner 2008].Figure 1: Two techniques studied in this article, each using a different strategy for making surgery images easier to look at. ABSTRACTWe present the first empirical study on using color manipulation and stylization to make surgery images more palatable. While aversion to such images is natural, it limits many people's ability to satisfy their curiosity, educate themselves, and make informed decisions. We selected a diverse set of image processing techniques, and tested them both on surgeons and lay people. While many artistic methods were found unusable by surgeons, edge-preserving image smoothing gave good results both in terms of preserving information (as judged by surgeons) and reducing repulsiveness (as judged by lay people). Color manipulation turned out to be not as effective.
