Description

3D modelling & visualization is a concern focus in the 3D GIS research field recently. The prime objective of any geosciences organization or geologist is to investigate & characterize the Earth's sub-surface in 3D. Along with the surface development, subsurface geological structure is paid more & more attention. However, it is very difficult to hold exactly subsurface geological structure information because subsurface geological structure can't be directly apperceived & the geological information obtained by ground drilling is only discrete point information. Constructing subsurface 3D volume model & visualizing the model based on discrete drilling data can offer a feasible approach to research on soil subsurface geological structure. The design of such geovisualizations requires careful consideration of how one can convey a 3D volumetric phenomenon, & how it changes through time, when the information is ultimately going to be delivered via a 2D computer screen. By doing so, we aim to improve user's ability to perceive, understand & explore the structure, spatial & temporal dimensions of transient sub-surface events.
