Triangulated surfaces are often the foundation of modeling a mineral deposit. Whether the surface is current topography, a fault plane or a thickness isopach an accurate surface is an integral part of the model. Creating this surface should be simple and easy, but in Vulcan there are so many options. Where do you start? This tutorial shows you how to create a simple surface triangulation in Vulcan and touches on some of the options you may want to use during creation.
Creating a surface triangulation begins with the input data. This data can be a topography map with strings at actual elevation or a set of points like drillhole collars or grade values. The data should be loaded in Vulcan and displayed in Envisage. Create the triangulation using the menu Model > Triangle Surface > Create. The panel that pops up will have several tabs, each with many buttons and checkboxes. This is a good time to introduce the second rule of Vulcan “When in doubt, accept the defaults.”
