Curvature attribute interpretation is a new interpretation technology rising in the recent two years. Curvature attributes provide images of structure and stratigraphy that complement those seen by the well accepted coherence algorithms. The article expounds the definition of the curvature, the physical meaning and its shortages in structural interpretation from the most basic mathematical definition...
Multiple-point geostatistics (MPS) simulation originates from geostatistical fields and allows extracting multiple-point structures from training images, after that MPS can copy these structures to the regions to be simulated. Porosity is quite significant to the characterization and prediction of transport properties. To simulate the porosity value, a porosity simulation method using continuous MPS...
This paper proposes the feature descriptor for 3D model similarity search using the distribution of normal directions on the simplified surface. Feature descriptor of 3D model should be invariant to translation, rotation and scale for its model. So this paper normalizes all the model using PCA and preprocesses surface mesh simplification to robust against noise. The normal is sampled in proportion...
Data sets resulting from physical simulations typically contain a multitude of physical variables. It is, therefore, desirable that visualization methods take into account the entire multi-field volume data rather than concentrating on one variable. We present a visualization approach based on surface extraction from multi-field particle volume data. The surfaces segment the data with respect to the...
