We present an algorithm for artistically modifying physically based shadows. With our tool, an artist can directly edit the shadow boundaries in the scene in an intuitive fashion similar to freeform curve editing. Our algorithm then makes these shadow edits consistent with respect to varying light directions and scene configurations, by creating a shadow mesh from the new silhouettes. The shado...

We introduce an approach for re-designing 3D shapes inspired by natural lines such as the contours and skeletons extracted from the natural objects in images. Designing an artistically creative and visually pleasing model is not easy for novice users. In this paper, we propose to convert such a design task to a computational procedure. Given a 3D object, we first compare its editable lines with...

Animated crowds offer modern methods to show both social relationships and emotions to enhance plain virtual scenes. When animation is created by an artist, it is a hard and time consuming process, but allows to create impressive results. On the other hand, when results do not need to be artistically accurate, more automated techniques are in place. Our solution contributes to the second group ...

In early India, people handcrafted jewellery out of natural materials found in abundance all over the country. Seeds, feathers, leaves, berries, fruits, flowers, animal bones, claws and teeth; everything from nature was affectionately gathered and artistically transformed into fine body jewellery. Even today such jewellery is used by the different tribal societies in India. It appears that both...

We introduce halftoning as a general primitive for real-time non-photorealistic shading. It is capable of producing a variety of rendering styles, ranging from engraving with lighting-dependent line width to pen-and-ink style drawings using prioritized stroke textures. Since monitor resolution is limited we employ a smooth threshold function that provides stroke antialiasing. By applying the ha...

Eight studies assessed the motive for sensory pleasure (MSP) involving a general disposition to enjoy and pursue pleasant nature-related experiences and avoid unpleasant nature-related experiences. The stated enjoyment of pleasant sights, smells, sounds, and tactile sensations formed a unitary construct that was distinct from sensation seeking, novelty preference, and need for cognition. MSP wa...

Data visualization is usually considered an expert field reserved for the computer science or data analysis specialist. In contrast, in this paper we argue that the approaches and theories from data visualization can form a rich contextual resource for teaching creative design principles to students. A conceptual data mapping model is proposed that describes a continuum between ‘traditional’ da...

The goal of this paper is methodological. It offers a comprehensive mapping of the theoretical positions on the ethical criticism of art, correcting omissions and inadequacies in the conceptual framework adopted in the current debate. Three principles are recommended as general guidelines: ethical amenability, basic value pluralism, and relativity to ethical dimension. Hence a taxonomy distingu...

In video games, High Dynamic Range (HDR) rendering is commonly used and allows us to render more photo-realistic looking images. HDR rendering uses a tone-mapping process to achieve a Low Dynamic Range (LDR) rendering result for a display. The process compresses or clamps HDR color information to fit LDR devices which typically have an 8-bit color resolution. There are a lot of tone-mapping alg...
