We use volumetric normal maps to represent normal vector glyphs that are subsequently applied to warp the gradients in the primary volume data. This method is ...
Abstract [en]. The work presented in this paper introduces volumetric normal maps for producing visual structure in direct. volume rendering (DVR) of 3D data ...
Our system allows the user to specify a fully general multi-dimensional transfer function with up to three axes. For instance, the first two axes can map data ...
This chapter presents texture-based volume rendering techniques that are used for visualizing three-dimensional data sets and for creating high-quality special ...

This paper presents a set of feature enhance- ment techniques coupled with hardware-accelerated non- photorealistic rendering for generating more ...
Volumetric data refers to a collection of samples in 3D space, each consisting of coordinates (x, y, z) and a corresponding value (v) representing properties ...
In this session we will summarize various approaches that make extensive use of graphics hardware for the rendering of volumetric data sets. In particular ...

We use predictable procedural noise – random-phase Gabor noise – to generate a high-frequency redistribution pattern and construct an opacity mapping function, ...
Apr 13, 2015 · A traditional transfer function uses a low-dimensional lookup table to map the volumetric scalar field to color and opacity. In this paper ...
Volume rendering is a set of techniques used to display a 2D projection of a 3D discretely sampled data set, typically a 3D scalar field.
