Precision Issues in EVS

Posted by on Mar 4, 2020 in Tips and Tricks | Comments Off on Precision Issues in EVS

This is an important subject that is long overdue to be discussed in detail.  There are several aspects of numeric precision that are relevant to EVS and our users, but two in particular warrant a detailed description. Precision of calculations and deliverable results Precision of graphical displays Both topics above are driven by the way that computers represent numbers, therefore we will address first how computers represent Float and Double numbers.  For those of you not familiar with the terms “Float” and “Double” as used in computer...

Free Training Class on Complex Fault Modeling

Posted by on Oct 17, 2019 in Training | Comments Off on Free Training Class on Complex Fault Modeling

I am pleased to announce the release of a new Training Class on Complex Fault Modeling. This 45 minute video explains, in detail, the processes involved in modeling a complex site with 4 faults and 6 fault blocks. This site is modeled using the technique we refer to as Prehistoric Geology, and we cover how to create the prehistoric .GEO file from your current stratigraphic geologic data in order to create a faulted model which honors the continuity of the geologic strata that existed prior to the ancient faulting. This is a free recorded...

EVS Advanced Training Class: How to Edit Stratigraphic Geology

Posted by on Sep 30, 2019 in Training | Comments Off on EVS Advanced Training Class: How to Edit Stratigraphic Geology

I am pleased to announce the release of a new EVS Advanced Training Class on How to Edit Stratigraphic Geology a.k.a. How to Develop Stratigraphic Geology from Hand Drawn Cross-Sections. This video workbook covers the techniques to employ the complex texture_geology and edit_horizon modules to their full advantage, and opens up new methodologies for customization of your stratigraphic geologic models.This video has been over one year in the making and is one of the most challenging ones we’ve completed to date. Though these two key...

How can I smooth a geologic surface even if it doesn’t honor my data?

Posted by on Oct 21, 2018 in Tips and Tricks | Comments Off on How can I smooth a geologic surface even if it doesn’t honor my data?

If I have surfaces that look like this with lots of peaks and troughs, is there an easy way to create a smooth surface, even if it doesn’t necessarily try to “honor” every point, more like a least squares fit? All of our estimation methods in krig_3d_geology honor your data, as best they can subject to your specified grid resolution.  The simplest way to get a smoother “apparent” surface is to coarsen your grid resolution.  However this method has some potential pitfalls, since the value computed at any give node...

Fault Surfaces in Earth Volumetric Studio

Posted by on Feb 7, 2017 in Tips and Tricks | Comments Off on Fault Surfaces in Earth Volumetric Studio

There are normally two reasons to create fault surfaces in EVS.  We either just want to display them, or we want to use them to create fault blocks as part of a more complex geologic model.  When we create fault blocks, we are using the surf_cut module and the fault surface is input to the right input port.  There are three main cases to consider with respect to the creation of fault surfaces: 1) Planar surfaces.  A planar surface is a surface which is flat.  It can be oriented in any way, but is has no curvature, bumps, etc.  This type of...
