Abstract: The visualisation of vector fields usually proceeds via geometric forms, such as arrows or streamlines. This paper describes an effective method for volume rendering vector fields in which vectors are assigned colour using a perceptually based colour map. The method is capable of displaying vector fields sampled at voxel rates in three dimensions. This is in contrast to geometric methods that require much lower sampling densities. The approach described automatically colour codes the local field attributes, such as critical points, and enables their emphasis via data windowing techniques. Case studies using gravitational fields and computational fluid dynamics demonstrate the method.

TL;DR: This work proposes a linear filtering scheme to extract local fiber orientations from micro computed tomography images and shows how to condense the local orientation information into visual representations, which results in densely sampled orientation maps.

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.
