Blend shape animation is the method of choice for keyframe facial animation: a set of blend shapes (key facial expressions) are used to define a linear space of facial expressions. However, in order to capture a significant range of complexity of human ...

An innovative lighting algorithm is presented that allows scenes to be displayed with approximate global illumination including ambient occlusion and sky-light effects at real-time rates. The method is scalable for high polygonal scenes and requires a ...

We present mathematical sketching, a novel, pen-based, modeless gestural interaction paradigm for mathematics problem solving. Mathematical sketching derives from the familiar pencil-and-paper process of drawing supporting diagrams to facilitate the ...

We are interested in enabling a generic sketch recognition system that would allow more natural interaction with design tools in various domains, such as mechanical engineering, military planning, logic design, etc. We would like to teach the system the ...

Various systems have explored the idea of inferring 3D models from sketched 2D outlines. In all of these systems the underlying modeling methodology limits the complexity of models that can be created interactively. The ShapeShop sketch-based modeling ...

Many diverse applications in different areas of computer graphics, including geometric modeling, rendering and animation, require dealing with sets which cannot be easily represented with a single function on a simple domain in a Euclidean space: ...

The transition from traditional 24-bit RGB to high dynamic range (HDR) images is hindered by excessively large file formats with no backwards compatibility. In this paper, we propose a simple approach to HDR encoding that parallels the evolution of ...

As Computer Graphics makes rapid strides in various aspects of digital shape modeling it is easy to lose perspective of the larger motivations for digital shape modeling in design and animation. This chapter provides a high level view of shape modeling ...
