We present a framework for geometric warps and deformations. The framework provides a conceptual and mathematical foundation for analyzing known warps and for developing new warps, and serves as a common base for many warps and deformations. Our framework is composed of two components: a generic modular algorithm for warps and deformations; and a concise,(More)
T he recognition that better use of existing internal knowledge could enhance survival chances of organizations has spawned substantial interest in the transferability of routinized, experiential learning to additional settings within the organization. Previous research has established that trustworthiness of the source enhances such knowledge transfer.(More)
(a) Flat colors (b) Complex texture Figure 1: A frame of cel animation with the foreground character painted by (a) the conventional method, and (b) our system. Abstract We present a method for applying complex textures to hand-drawn characters in cel animation. The method correlates features in a simple, textured, 3-D model with features on a hand-drawn(More)
When effort is observable to peers, students may try to avoid social penalties by conforming to prevailing norms. To test this hypothesis, we first consider a natural experiment that introduced a performance leaderboard into computer-based high school courses. The result was a 24 percent performance decline. The decline appears to be driven by a desire to(More)
When effort or investment is observable to peers, students may act to avoid social penalties by conforming to prevailing norms. We explore this hypothesis in two settings. We first consider a natural experiment that newly introduced a leaderboard into existing computer-based remedial high school courses, revealing top performers to the rest of the class.(More)
