Depth-Peeling for Texture-Based Volume Rendering

We present the concept of volumetric depth-peeling. The proposed method is conceived to render interior and exterior iso-surfaces for a fixed iso-value and to blend them without the need to render the volume multiple times. The main advantage of our method over pre-integrated volume rendering is the ability to extract arbitrarily many iso-layers for the given iso-value. Up to now, pre-integrate...

Texture Partitioning and Packing for Accelerating Texture-based Volume Rendering

To apply empty space skipping in texture-based volume rendering, we partition the texture space with a box-growing algorithm. Each sub-texture comprises of neighboring voxels with similar densities and gradient magnitudes. Sub-textures with similar range of density and gradient magnitude are then packed into larger ones to reduce the number of textures. The partitioning and packing is independe...

Improving cache locality for GPU-based volume rendering

We present a cache-aware method for accelerating texture-based volume rendering on a graphics processing unit (GPU). Because a GPU has hierarchical architecture in terms of processing and memory units, cache optimization is important to maximize performance for memory-intensive applications. Our method localizes texture memory reference according to the location of the viewpoint and dynamically...

Interactive Texture-Based Volume Rendering for Large Data Sets

tific computation and simulation. Stateof-the-art simulations of physical systems can generate terabytes to petabytes of time-varying data where a single time step can contain more than a gigabyte of data per variable. As memory sizes continue to increase, the size of data sets will likely increase at a comparably high rate. The key to understanding this data is visualizing the global and local...
