Image-Based TF Colorization With CNN for Direct Volume Rendering
IEEE Access, 2021 In the direct volume rendering (DVR), it often takes a long time for a novice to manipulate the transfer function (TF) and analyze the volume data. To lessen the difficulty in volume rendering, several researchers have developed deep learning techniques.

Direct Volume Rendering with Nonparametric Models of Uncertainty [PDF]
IEEE Transactions on Visualization and Computer Graphics, 2021 We present a nonparametric statistical framework for the quantification, analysis, and propagation of data uncertainty in direct volume rendering (DVR). The state-of-the-art statistical DVR framework allows for preserving the transfer function (TF) of the ground truth function when visualizing uncertain data; however, the existing framework is ...

Visibility-Aware Direct Volume Rendering [PDF]
Journal of Computer Science and Technology, 2011 Direct volume rendering (DVR) is a powerful visualization technique which allows users to effectively explore and study volumetric datasets. Different transparency settings can be flexibly assigned to different structures such that some valuable information can be revealed in direct volume rendered images (DVRIs).

Direct volume rendering of unstructured grids [PDF]
Computers & Graphics, 2003 Abstract This paper investigates three categories of algorithms for direct volume rendering of unstructured grids, which are image-space, object-space, and hybrid methods. We propose three new algorithms. Cell Projection algorithm, which falls into object-space category, is capable of rendering non-convex meshes through a simple yet efficient sorting
