1001 tales of texture mapping

Abstract

Texture mapping is a well-known technology, that has been implemented in Gocad very early on, around 1993, enhanced to support color textures in 1995, and has been largely used for texturing aerial pictures on top of topography maps at ChevronTexaco. In addition to this common use, texture mapping can be used for many other practical purposes, and we will share some of them, that we have used in the past few years. Most of them are merely based on usage of basic Gocad tools. The more advanced ones involved development of new code in ChevronTexaco proprietary plugins. After introducing the basics of texture mapping and texture extraction theories, we will describe a series of practical applications, and explain how to reproduce them: - extraction of a 3D attribute onto structural surfaces (horizons, faults) - geological interpretation between wells (draping from seismic cube onto fence diagrams) - well path planning (draping of rock mechanic analysis property onto curtain built along proposed well path) - draping of a high-resolution property (available on a pointset) onto a low-resolution TSurf (using an intermediate 2D Voxet) - display of crooked 2D seismic lines (using UV mapping) - display of oil column height in volumetrics computation - seismic Allan maps: extraction of property away from fault, displayed as texture on fault surface - high resolution fault property computation and display using UV texture mapping.
