Transition Contour Synthesis with Dynamic Patch Transitions
In this article, we present a novel approach for modulating the shape of transitions between terrain materials to produce detailed and varied contours where blend resolution is limited. Whereas texture splatting and blend mapping add detail to transitions at the texel level, our approach addresses the broader shape of the transition by introducing intermittency and irregularity. Our results have proven that enriched detail of the blend contour can be achieved with a performance competitive to existing approaches without additional texture, geometry resources, or asset preprocessing. We achieve this by compositing blend masks on-the-fly with the subdivision of texture space into differently sized patches to produce irregular contours from minimal artistic input. Our approach is of particular importance for applications where GPU resources or artistic input is limited or impractical
3D Face Synthesis Driven by Personality Impression
Synthesizing 3D faces that give certain personality impressions is commonly
needed in computer games, animations, and virtual world applications for
producing realistic virtual characters. In this paper, we propose a novel
approach to synthesize 3D faces based on personality impression for creating
virtual characters. Our approach consists of two major steps. In the first
step, we train classifiers using deep convolutional neural networks on a
dataset of images with personality impression annotations, which are capable of
predicting the personality impression of a face. In the second step, given a 3D
face and a desired personality impression type as user inputs, our approach
optimizes the facial details against the trained classifiers, so as to
synthesize a face which gives the desired personality impression. We
demonstrate our approach for synthesizing 3D faces giving desired personality
impressions on a variety of 3D face models. Perceptual studies show that the
perceived personality impressions of the synthesized faces agree with the
target personality impressions specified for synthesizing the faces. Please

Attack on the clones: managing player perceptions of visual variety and believability in video game crowds
Crowds of non-player characters are increasingly common in contemporary video games. It is often the case that individual models are re-used, lowering visual variety in the crowd and potentially affecting realism and believability. This paper explores a number of approaches to increase visual diversity in large game crowds, and discusses a procedural solution for generating diverse non-player character models. This is evaluated using mixed methods, including a âclone spottingâ activity and measurement of impact on computational overheads, in order to present a multi-faceted and adjustable solution to increase believability and variety in video game crowds
