چکیده

The resolution obtained in volume rendering is greatly increased over known methods through the introduction of super resolution techniques which make it possible to enlarge the view of the dataset without the introduction of unnecessary positional, gradient and opacity errors. In this paper our "Super Resolution" technique will be introduced along with a corresponding hardware design.

Hardware Assisted Multichannel Volume Rendering

We explore real time volume rendering of multichannel data for volumes with color and multi-modal information. We demonstrate volume rendering of the Visible Human Male color dataset and photo-realistic rendering of voxelized terrains, and achieve high quality visualizations. We render multi-modal volumes utilizing hardware programmability for accumulation level mixing, and use CT and MRI infor...

Real-Time Super Resolution Contextual Close-up of Clinical Volumetric Data

We present an illustrative visualization system for real-time and high quality rendering of clinical volumetric medical data. Our technique is inspired by a medical illustration technique for depicting contextual close-up views of selected regions of interest where internal anatomical features are rendered in high detail. Our method integrates four important components: decimation of original v...

Advanced techniques for high-quality multi-resolution volume rendering

We present several improvements for compression based multi-resolution rendering of very large volume data sets at interactive to real-time frame rates on standard PC hardware. The algorithm accepts scalar or multi-variant data sampled on a regular grid as input. The input data is converted into a compressed hierarchical wavelet representation in a pre-processing step. During rendering, the wav...

Towards Real Time Volume Rendering

The task of real time rendering of today’s volumetric datasets is still being tackled by several research groups. A quick calculation of the amount of computation required for real-time rendering of a high resolution volume puts us in the teraflop range. Yet, the demand to support such rendering capabilities is increasing due to emerging technologies such as virtual surgery simulation and rapid...

Interactive Visualization of Very Large Medical Datasets using Point-based Rendering

Visualizing high-resolution volumetric medical datasets is a challenging task. Current off-the-shelf graphics hardware supports interactive texture-based volume-rendering of volumetric datasets up to a resolution of 512 data points only. We present a method that allows us to visualize higher-resolution datasets, providing images similar to texture-based volume-rendering techniques at interactiv...
