Visibility Culling for Time-Varying Volume Rendering Using Temporal Occlusion Coherence
Typically there is a high coherence in data values between neighboring time steps in an iterative scientific software simulation; this characteristic similarly contributes to a co...

Adaptive 4-8 Texture Hierarchies
We address the texture level-of-detail problem for extremely large surfaces such as terrain during realtime, view-dependent rendering. A novel texture hierarchy is introduced base...

ImageSurfer: A Tool for Visualizing Correlations between Two Volume Scalar Fields
ImageSurfer is a tool designed to explore correlations between two 3D scalar fields. Our scientific goal was to determine where a protein is located, and how much its concentratio...

Projecting Tetrahedra without Rendering Artifacts
Hardware-accelerated direct volume rendering of unstructured volumetric meshes is often based on tetrahedral cell projection, in particular, the Projected Tetrahedra (PT) algorith...

Constrained Inverse Volume Rendering for Planetary Nebulae
Determining the three-dimensional structure of distant astronomical objects is a challenging task, given that terrestrial observations provide only one viewpoint. For this task, b...
