This paper discusses the use of two different approaches for computing the “accessibility” of a surface. These metrics characterize how easily a surface may be touched by a spherical probe. The paper also presents various acceleration techniques for accessibility. The idea of surface accessibility is extended to include “global accessibility” which measures the ability of a spherical probe to enter a structure from outside as well as to fit locally on the surface. The visual effect of shading…

Vicinity shading for enhanced perception of volumetric data

A shading model for volumetric data which enhances the perception of surfaces within the volume by incorporating uniform diffuse illumination, which arrives equally from all directions at each surface point in the volume.

Accessibility Analysis Using Computer Graphics Hardware

Novel and efficient algorithms for computing accessible directions for tactile probes used in 3D digitization with Coordinate Measuring Machines are presented.

Interactive display of isosurfaces with global illumination

This work introduces a method to precompute or lazily compute global illumination to improve interactive isosurface renderings, and uses this volume to allow dynamic manipulation of lighting, viewpoint and isovalue.

Separable Approximation of Ambient Occlusion

This paper presents a fast easy-to-implement separable approximation to screen space ambient occlusion, and shows that visually convincing results close to a non-separable occlusions can be obtained at much higher performance.

Displays for exploration and comparison of nested or intersecting surfaces

New visualization techniques for general layered surfaces, and intersecting surfaces in particular, designed for scientists with problems that require such display, enabled by a union/intersection refactoring of intersecting surface that converts them into nested surfaces, which are more easily treated for visualization.

Ambient occlusion for animated characters

A novel technique that automatically determines the correspondence between animation parameters and per-vertex ambient occlusion using a set of reference poses as its input and is directly applicable to computer games running on current graphics hardware.

Ambient Occlusion and Edge Cueing for Enhancing Real Time Molecular Visualization

The proposed approach includes an innovative technique for efficient computation and storage of ambient occlusion terms, a small set of GPU accelerated procedural impostors for space-fill and ball-and-stick rendering, and novel edge-cueing techniques to enhance the real-time visualization of simple or complex molecules in space fill mode.

Natural-looking strokes for drawing applications

This paper presents an algorithm for generating realistic drawing strokes in real-time that can take on the appearance of pastels, charcoals, or crayons that can be used as a height field and tablet inputs.

Bent Normals and Cones in Screen-space

This work describes how to compute bent normals and bent cones in combination with screen-space ambient occlusion in order to combine the speed and simplicity of AO with physically more plausible lighting.

Hybrid Ambient Occlusion

An approach to ambient occlusion combining object and image space techniques in a deferred shading context that smoothly varying ambient terms in occluded areas at interactive frame rates without any precomputation is introduced.

Convolution surfaces

The solution in this paper is to extend the surfaces introduced by Blinn by using three-dimensional convolution with skeletons composed of polygons or curves, which permit fluid topology changes, seamless part joins, and efficient implementation.
