MFA-DVR: Direct Volume Rendering of MFA Models

Abstract

Fig. 1: Volume rendering results using MFA-DVR, a ray casting based direct volume rendering algorithm using the MFA model. (a) Volume rendering results on a sparse dataset of Gaussian Beam using MFA-DVR compared with structured volume rendering algorithm using NNS or trilinear interpolation, and unstructured volume rendering algorithms. The same structured grid dataset is used for all the algorithms evaluated, and treated as unstructured grid for unstructured volume rendering algorithms. (b) Volume rendering results on Aneurysm dataset using the MFA model with different compression ratios (CRs). (c) Zoom in view of (b).

Achieving Better Energy Efficiency in Volume Analysis and Direct Volume Rendering Descriptor Computation

“…Some details of such methods are described later, in Section 2 of this paper. Beyond DVR, there are volume data analysis applications reported for isosurfacing, registration (e.g., [9]), etc., and classic speed and accuracy studies have been carried out in such domains (with the importance of accuracy receiving increased recent attention, as in [10]). However, focus here is on them as components that commonly enable DVR end renderings.…”
