Uncertainty Visualization Methods in Isosurface Volume Rendering

Uncertainty Visualization

We describe two techniques for rendering isosurfaces in multiresolution volume data such that the uncertainty (error) in the data is shown in the resulting visualization. In general the visualization of uncertainty in data is difficult, but the nature of isosurface rendering makes it amenable to an effective solution. In addition to showing the error in the data used to generate the isosurface,...

Interval Set: A Volume Rendering Technique Generalizing Isosurface Extraction

Volume Visualization of Large Tetrahedral Meshes on Low Cost Platforms

In this paper, we present an interactive system for visualization of three-dimensional scalar fields. The system has been designed in order to overcome some of the problems posed by very large volume data sets. The adopted solution exploits an efficient multiresolution data structure based on a tetrahedral domain decomposition. The mesh to be rendered can be selectively refined over areas that ...

Efficient and Effective Volume Visualization with Enhanced Isosurface Rendering

1 Compared with full volume rendering, isosurface rendering has 2 several well recognized advantages in efficiency and accuracy. 3 However, standard isosurface rendering has some limitations in ef4 fectiveness. First, it uses a monotone colored approach and can 5 only visualize the geometry features of an isosurface. The lack 6 of the capability to illustrate the material property and the inter...

Visualization of gridded scalar data with uncertainty in geosciences

Characterization of the earth’s subsurface involves the construction of 3D models from sparse data and so leads to simulation results that involve some degree of uncertainty. This uncertainty is often neglected in the subsequent visualization, due to the fact that no established methods or available software exist. We describe a visualization method to render scalar fields with a probability de...
