Abstract

Interactive manipulation tools are widely used in many computer-aided applications. We focus on two specific tools to modify 3D geoscientific models. The first one is dedicated to the interactive editing of micro-layers in a reservoir. This new tool allows the user to drag under constraints the trace of micro-horizons on a special-purpose cross-section. The second part presents a new paradigm for interactive sealed model updating. This new methodology, based on a local parameterization coupled with Delaunay constrained triangulation, and on the use of the DSI algorithm, allows the user to interactively displace consistently a horizon along a fault in a 3D model while keeping a perfect contact between the two objects.
