TLDR
A technique for rendering images of volumes containing mixtures of materials is presented, which allows both the interior of a material and the boundary between materials to be colored.Abstract:
A technique for rendering images of volumes containing mixtures of materials is presented. The shading model allows both the interior of a material and the boundary between materials to be colored. Image projection is performed by simulating the absorption of light along the ray path to the eye. The algorithms used are designed to avoid artifacts caused by aliasing and quantization and can be efficiently implemented on an image computer. Images from a variety of applications are shown.read more

Imaging vector fields using line integral convolution
Brian Cabral,Leith Casey Leedom +1 more
TL;DR: This approach builds on several previous texture generation and filtering techniques but is unique because it is local, one-dimensional and independent of any predefined geometry or texture.

A reflectance model for computer graphics
TL;DR: In this paper, the spectral energy distribution of the reflected light from an object made of a specific real material is obtained and a procedure for accurately reproducing the color associated with the spectrum is discussed.

Fast volume rendering using a shear-warp factorization of the viewing transformation
Philippe Lacroute,Marc Levoy +1 more
TL;DR: A new object-order rendering algorithm based on the factorization of a shear-warp factorization for perspective viewing transformations is described that is significantly faster than published algorithms with minimal loss of image quality.

Three-dimensional alpha shapes
TL;DR: This article introduces the formal notion of the family of α-shapes of a finite point set in R, a well-defined polytope, derived from the Delaunay triangulation of the point set, with a parameter α ε R controlling the desired level of detail.

TL;DR: In this paper, a divide-and-conquer approach is used to generate inter-slice connectivity, and then a case table is created to define triangle topology using linear interpolation.

Display of surfaces from volume data
TL;DR: In this article, a volume-rendering technique for the display of surfaces from sampled scalar functions of 3D spatial dimensions is discussed, which is not necessary to fit geometric primitives to the sampled data; images are formed by directly shading each sample and projecting it onto the picture plane.
