Abstract

Expressive is the joint symposium on Computational Aesthetics, Non-Photorealistic Animation and Rendering, and Sketch-Based Interfaces and Modeling. Expressive 2014 is the fourth annual Expressive event and we have returned to Vancouver, where the first Expressive was also held.

Expressive's three subconferences have distinct but related agendas. Computational Aesthetics bridges the analytic and synthetic by integrating aspects of computer science, philosophy, psychology, and the fine, applied, and performing arts. CAe seeks to facilitate both the analysis and the augmentation of creative behaviors. Non-Photorealistic Animation and Rendering is concerned with computational techniques for visual communication; such techniques usually generate imagery and motion which is expressive, rather than photorealistic, although possibly including realistic elements. The goal of the Sketch-Based Interfaces and Modeling symposium is to explore the models, algorithms, and technologies needed to enable effective sketch-based interfaces. SBIM investigates novel methods for classification and recognition of hand-drawn shapes, and ways of using these techniques for creating or editing text, mathematics, and 3D shapes.

SESSION: Painting & interaction

Smoke Brush

Non-Photorealistic Rendering covers a wide range of visual effects, and much work has been dedicated to create digital representations of traditional media --- either through artist controls or programmatically. We explore a variation of this work, ...

Painting with triangles

Although vector graphics offer a number of benefits, conventional vector painting programs offer only limited support for the traditional painting metaphor. We propose a new algorithm that translates a user's mouse motion into a triangle mesh ...

RealPigment: paint compositing by example

The color of composited pigments in digital painting is generally computed one of two ways: either alpha blending in RGB, or the Kubelka-Munk equation (KM). The former fails to reproduce paint like appearances, while the latter is difficult to use. We ...

Creating personalized jigsaw puzzles

Designing aesthetically pleasing and challenging jigsaw puzzles is considered an art that requires considerable skill and expertise. We propose a tool that allows novice users to create customized jigsaw puzzles based on the image content and a user-...

Modular line-based halftoning via recursive division

We present a new approach for stippling by recursively dividing a grayscale image into rectangles with equal amount of ink, then we use the resulting structure to generate novel line-based halftoning techniques. We present four different rendering ...

Authorial subjective evaluation of non-photorealistic images

I argue in favor of a systematic subjective evaluation of non-photorealistic images. Objective measurements are hard to design, and quantitative user studies are problematic for a multiplicity of reasons. Subjective evaluations are not quantitative but ...

SESSION: Color & perception

ChromoStereoscopic rendering for trichromatic displays

The chromostereopsis phenomenom leads to a differing depth perception of different color hues, e.g., red is perceived slightly in front of blue. In chromostereoscopic rendering 2D images are produced that encode depth in color. While the natural ...

Stylized keyframe animation of fluid simulations

We present a method that combines hand-drawn artwork with fluid simulations to produce animated fluids in the visual style of the artwork. Given a fluid simulation and a set of keyframes rendered by the artist in any medium, our system produces a set of ...

Hierarchical motion brushes for animation instancing

Our work on "motion brushes" provides a new workflow for the creation and reuse of 3D animation with a focus on stylized movement and depiction. Conceptually, motion brushes expand existing brush models by incorporating hierarchies of 3D animated ...
