Video: New in EVS 2021.4.2
This 40 minute training video is free to everyone and will introduce some of the new (and required) changes to EVS 2021.4.2 and how to best use the C Tech Web Scene viewer. ...
read moreNew EVS Training Video: Advanced use of the place text module
In an effort to keep all of our users both entertained and educated during these times, we’ve put together another free training video on advanced use of the place text module. This is the second (permanently free) video in less than a week on powerful but underused EVS modules.As stated in the last announcement, we have made the four Intro Series videos available on YouTube as well as these new training videos on the buildings and place_text modules.I hope that these new training materials will help keep you engaged and fruitfully...
read morePrecision 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...

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...
read moreHow 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...
read moreFree Mini Class on Advanced Visualization Techniques
C Tech will conduct a free mini-class on Advanced Visualization Techniques using Earth Volumetric Studio, on July 12, 2017 at 11:00 am EDT. We will cover some clever tricks with the buffer and union modules and some surprises. The class was open to the first 50 registrants. It was posted Thursday June 22 and the final registrant was early Monday morning on June 26. The recorded video of the class is below.
read moreFault 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...
read moreVolumetrics Study: Studio vs. MVS
Prior to the formal release of Studio, we did a comprehensive volumetrics study because we were making significant changes to both volumetrics and subsetting (e.g. plume) modules in Studio. In that study we looked at our new Studio algorithms compared with MVS as a function of grid resolution. We’ve always known that as you increase the resolution of your model, the accuracy improves and we always see volumetrics results approach an asymptotic “theoretical” value as the grid resolution is increased. Our new algorithms in...
read moreModeling of Karst Geology with Caves
One of C Tech’s distributor’s in China asked us to explain how Earth Volumetric Studio could be used to model Caves. The most straightforward approach is to use indicator kriging (e.g. indicator_geology module) and treat the cave as as if it were another material in the site lithology. The video below takes this approach. You can also apply adaptive_indicator_kriging to stratigraphic geologic models. In this way, if you have a site with stratigraphic geology, you can include a cave based on lithology data within the...
