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 ...
متن کاملVolume Rendering
This report summarizes my research on the visualization of scalar fields and the rendering of participating media. A strong focus of my work is on the development of optical models for exploring and visualizing volumetric data sets interactively. In particular, my research is concentrated on goal-oriented optical models that offer simple control over the visual properties of a visualization com...
متن کاملVolume Rendering
Rapid advances in hardware have been transforming revolutionary approaches in computer graphics into reality. One typical example is the raster graphics that took place in the seventies, when hardware innovations enabled the transition from vector graphics to raster graphics. Another example which has a similar potential is currently shaping up in the field of volume graphics. This trend is roo...
متن کاملHierarchically Accelerated Ray Casting for Volume Rendering with Controlled Error
Ray casting for volume rendering can be accelerated by taking large steps over regions where data need not be processed at a ne resolution. A new implementation is described that utilizes both a user-speciied data importance and a high-level data model in appropriate regions to achieve acceleration. Previously reported work exploited high accumulated opacity, transparency, and nearly constant v...
متن کاملReal-time volume rendering
We present Cube-4, a special-purpose volume rendering architecture that is capable of rendering high-resolution (e.g., 10243) datasets at 30 frames per second. The underlying algorithm, called slice-parallel ray-casting, uses tri-linear interpolation of samples between data slices for parallel and perspective projections. The architecture uses a distributed interleaved memory, several parallel ...
