Frequency Analysis of Gradient Estimators in Volume Rendering [PDF]

, 1995
Gradient information is used in volume rendering to classify and color samples along a ray. In this paper, we present an analysis of the theoretically ideal gradient estimator and compare it to some commonly used gradient estimators.

Multiprocessor Iso-surface Volume Rendering [PDF]

, 2001
The rendering of iso-surfaces in a scalar 3D dataset can be performed with a new algorithm, called iso surface volume rendering. This algorithm does not introduce sampling artifacts or artifacts due to triangularization.
