Depth of Field Effects for Interactive Direct Volume Rendering

In this paper, a method for interactive direct volume rendering is proposed for computing depth of field effects, which previously were shown to aid observers in depth and size perception of synthetically generated images. The presented technique extends those benefits to volume rendering visualizations of 3D scalar fields from CT/MRI scanners or numerical simulations. It is based on incrementa...

Segmentation Assisted Object Distinction for Direct Volume Rendering

Ray Casting is a direct volume rendering technique for visualizing 3D arrays of sampled data. It has vital applications in medical and biological imaging. Nevertheless, it is inherently open to cluttered classification results. It suffers from overlapping transfer function values and lacks a sufficiently powerful voxel parsing mechanism for object distinction. In this work, we are proposing an ...

Depth of field in light field rendering

This paper focuses on the sampling problem in light field rendering (LFR) that is a fundamental approach to image based rendering. Quality of LFR depends on a light ray database generated from pre-acquired images, since image synthesis is a process of gathering appropriate light ray data from the database. For improving the quality, interpolation of light ray data is effective. It is based on a...

Texture-enhanced Direct Volume Rendering

Direct volume rendering (DVR) is a flexible technique for visualizing and exploring scientific and biomedical volumetric data sets. Transfer functions associate field values with colors and opacities, however, for complex data are often not sufficient for encoding all relevant information. We introduce a novel visualization technique termed texture-enhanced DVR to visualize supplementary data s...

Progressive CPU Volume Rendering with Sample Accumulation

We present a new method for progressive volume rendering by accumulating object-space samples over successively rendered frames. Existing methods for progressive refinement either use image space methods or average pixels over frames, which can blur features or integrate incorrectly with respect to depth. Our approach stores samples along each ray, accumulates new samples each frame into a buff...
