    • 2D Shading for Cel Animation 

      Hudon, Matis; Pagés, Rafael; Grogan, Mairéad; Ondřej, Jan; Smolić, Aljoša (ACM, 2018)
      We present a semi-automatic method for creating shades and self-shadows in cel animation. Besides producing attractive images, shades and shadows provide important visual cues about depth, shapes, movement and lighting of ...
    • 3D Sketching for Interactive Model Retrieval in Virtual Reality 

      Giunchi, Daniele; James, Stuart; Steed, Anthony (ACM, 2018)
      We describe a novel method for searching 3D model collections using free-form sketches within a virtual environment as queries. As opposed to traditional sketch retrieval, our queries are drawn directly onto an example ...
    • Abstract Depiction of Human and Animal Figures: Examples from Two Centuries of Art and Craft 

      Dodgson, Neil A. (ACM, 2018)
      The human figure is important in art. I discuss examples of the abstract depiction of the human figure and the challenge faced in attempting to mimic algorithmically what human artists can achieve. The challenge lies in ...
    • Approaches for Local Artistic Control of Mobile Neural Style Transfer 

      Reimann, Max; Klingbeil, Mandy; Pasewaldt, Sebastian; Semmo, Amir; Döllner, Jürgen; Trapp, Matthias (ACM, 2018)
      This work presents enhancements to state-of-the-art adaptive neural style transfer techniques, thereby providing a generalized user interface with creativity tool support for lower-level local control to facilitate the ...
    • Automatic Generation of Geological Stories from a Single Sketch 

      Garcia, Maxime; Cani, Marie-Paule; Ronfard, Rémi; Gout, Claude; Perrenoud, Christian (ACM, 2018)
      Describing the history of a terrain from a vertical geological cross-section is an important problem in geology, called geological restoration. Designing the sequential evolution of the geometry is usually done manually, ...
    • Brush Stroke Synthesis with a Generative Adversarial Network Driven by Physically Based Simulation 

      Wu, Rundong; Chen, Zhili; Wang, Zhaowen; Yang, Jimei; Marschner, Steve (ACM, 2018)
      We introduce a novel approach that uses a generative adversarial network (GAN) to synthesize realistic oil painting brush strokes, where the network is trained with data generated by a high-fidelity simulator. Among ...
    • Computational Light Painting and Kinetic Photography 

      Huang, Yaozhun; Tsang, Sze-Chun; Wong, Hei-Ting Tamar; Lam, Miu-Ling (ACM, 2018)
      We present a computational framework for creating swept volume light painting and kinetic photography. Unlike conventional light painting technique using hand-held point light source or LED arrays, we move a flat-panel ...
    • Context-based Sketch Classification 

      Zhang, Jianhui; Chen, Yilan; Li, Lei; Fu, Hongbo; Tai, Chiew-Lan (ACM, 2018)
      We present a novel context-based sketch classification framework using relations extracted from scene images. Most of existing methods perform sketch classification by considering individually sketched objects and often ...
    • An ego-altruist society 

      Cruz, Pedro M.; Cunha, André B. (ACM, 2018)
      This artwork is an artificial life simulation that shows how a society of agents flourishes with the symbiotic interactions between the egotist and altruist extremes. Egotist agents seek and absorb energy. Altruist agents ...
    • Expressive 2018: frontmatter 

      Aydın, Tunç and Sýkora, Daniel (ACM, 2018)
    • Fluid Brush 

      Abraham, Sarah; Vouga, Etienne; Fussell, Donald (ACM, 2018)
      Digital media allows artists to create a wealth of visually-interesting effects that are impossible in traditional media. This includes temporal effects, such as cinemagraph animations, and expressive fluid effects. Yet ...
    • Implicit Representation of Inscribed Volumes 

      Sahbaei, Parto; Mould, David; Wyvill, Brian (ACM, 2018)
      We present an implicit approach for constructing smooth isolated or interconnected 3-D inscribed volumes which can be employed for volumetric modeling of various kinds of spongy or porous structures, such as volcanic rocks, ...
    • MNPR: A Framework for Real-Time Expressive Non-Photorealistic Rendering of 3D Computer Graphics 

      Montesdeoca, Santiago E.; Seah, Hock Soon; Semmo, Amir; Bénard, Pierre; Vergne, Romain; Thollot, Joëlle; Benvenuti, Davide (ACM, 2018)
      We propose a framework for expressive non-photorealistic rendering of 3D computer graphics: MNPR. Our work focuses on enabling stylization pipelines with a wide range of control, thereby covering the interaction spectrum ...
    • Motion-coherent stylization with screen-space image filters 

      Bléron, Alexandre; Vergne, Romain; Hurtut, Thomas; Thollot, Joëlle (ACM, 2018)
      One of the qualities sought in expressive rendering is the 2D impression of the resulting style, called flatness. In the context of 3D scenes, screen-space stylization techniques are good candidates for flatness as they ...
    • Reducing Affective Responses to Surgical Images through Color Manipulation and Stylization 

      Besançon, Lonni; Semmo, Amir; Biau, David; Frachet, Bruno; Pineau, Virginie; Sariali, El Hadi; Taouachi, Rabah; Isenberg, Tobias; Dragicevic, Pierre (ACM, 2018)
      We 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, ...
    • The Role of Grouping in Sketched Diagram Recognition 

      Ghodrati, Amirhossein; Blagojevic, Rachel; Guesgen, Hans W.; Marsland, Stephen; Plimmer, Beryl (ACM, 2018)
      An early phase of sketched diagram recognition systems consists of grouping digital ink into possible shapes. This survey presents the key literature on automatic grouping techniques in sketch recognition. In addition, we ...
    • Sculpture Paintings 

      Arpa, Sami; Süsstrunk, Sabine; Hersch, Roger D. (ACM, 2018)
      We present a framework for automatically creating a type of artwork in which 2D and 3D contents are mixed within the same composition. These artworks create plausible effects for the viewers by showing a different relationship ...

      Entem, Even; Parakkat, Amal Dev; Cani, Marie-Paule; Barthe, Loïc (ACM, 2018)
      Complex vector drawings serve as convenient and expressive visual representations, but they remain difficult to edit or manipulate. For clean-line vector drawings of smooth organic shapes, we describe a method to automatically ...
    • Stylized Stereoscopic 3D Line Drawings from 3D Images 

      Istead, Lesley; Kaplan, Craig S. (ACM, 2018)
      Stereoscopic 3D (S3D) line drawings were introduced by Sir Charles Wheatstone in 1838. S3D line drawings persist today in various art forms, such as comic books. Stereoscopic 3D line drawings may be hand-drawn or generated ...
