The MVS Resistance

Jan 22, 2018 in Announcements

I realize that some C Tech’s MVS users are resisting migrating to Earth Volumetric Studio because they are a bit daunted by the need to use Python syntax in modules like node_computation vs. the non-standard “equation” syntax used in modules like data_math and field_math. I encourage you to submit examples of your most complex equations to and I will be preparing a short tutorial on how to use node_computation and to demonstrate just how easy it is to do these same operations in Earth Volumetric Studio. By the way.  The only modules where you need to use Python (new) syntax vs. the MVS (old) syntax are: node_computation (replaces data_math, coordinate_math and field_math):  Though I will acknowledge that it seems more difficult to have to write a Python script to do something as simple as adding, multiplying or dividing, such a script is truly trivial to create.  However, if you ever want to do something really complicated, it is now possible, where it was not before.  It goes far beyond MVS’ capabilities. format_string (replaces string_format):  The biggest issue is that it is different.  What we had before was non-standard.  You couldn’t look it up on the internet because it was unique to MVS.  What we use now is Python and it is extensible and globally accepted. trigger_script: Though it does replace link_modules it is really a new module and can do far more than link_modules could ever imagine.    It goes far beyond MVS’ capabilities. The recent Microsoft updates to Windows 7 that left many of our users temporarily unable to run their software should serve as a warning to anyone clinging to MVS.  We appreciate that when updating an old MVS project, it may be quicker (and perhaps cheaper) in the near-term to continue doing that work in MVS, but the longer you delay, the greater risk you impose on the future.  Over the past 25+ years we’ve faced numerous Windows updates that have caused catastrophic failures of various types to our software.  You can rest assured that if and when this happens we will quickly respond, as we always have.  However, we have no plans to respond to upgrade MVS.  Our focus is and will be on Earth Volumetric Studio and therefore it is imperative that all of our customers make a dedicated effort to fully transition away from...

On the death of Dr. Christopher Rautman, C Tech’s Chief Geologist

May 22, 2017 in Announcements

It is with great sadness that I announce that Dr. Christopher Rautman, C Tech’s Chief Geologist passed away on May 12th from complications related to an ongoing illness. I’ve known, liked, worked with and respected Chris since we first met ~20 years ago when he was at Sandia National Laboratories.  The first projects he tackled with our software included the Yucca Mountain Nuclear Repository and the salt domes and solution mined caverns used to store the U.S. Strategic Petroleum Reserves.  Over the years that Chris was at Sandia, the projects where he employed our software were some of the most challenging ones C Tech encountered, and that helped to make our software much better.  There are many important features in our software that trace back to Chris’ work and suggestions.  Under his guidance, Sandia co-funded the development of 3D Printing technology in MVS (the predecessor to Earth Volumetric Studio).  This lead to current modules like intersection, intersection_shell & union, as well as multiple enhancements to our VRML exporting which now allows us to create 3D PDFs and Sketchfab exports in addition to 3D printing.  Anyone who has used our software to model salt domes or solution mined caverns has probably worked directly with Chris, but if not, you should know that the techniques used there are directly attributable to his efforts. When Chris retired from Sandia 5 years ago, I was very excited to have him join C Tech’s team where his vast experience and keen mind was put to good use.  He took the lead on many challenging consulting projects and one of the things he could do, that I can’t imagine being able to replace, was finding, interpreting and digitizing 50-100 year old drilling records that were locked away in the archives of organizations like the Texas Railroad Commission. To see the 3D models that he created from paper drawings that were decades old is the stuff of Sci-Fi movies. I will miss Chris. I learned a great deal every time I worked with him and I counted him as a true friend. Reed Copsey, President C Tech Development...

New Training Videos: 3D Kriging and Advanced Gridding

Sep 6, 2016 in Announcements, Training

We have just posted two new series of public training videos for Earth Volumetric Studio. The first series is on 3D Kriging in three parts: Part One focuses on krig_3d, some of its basic properties and discusses the limitations of its flat-topped rectilinear gridding in anticipation of Part Two. Part Two demonstrates how easy it is to incorporate krig_3d_geology when doing 3D kriging so that your grid is conformal to site topography and/or includes site stratigraphy. Part Three introduces draw_lines and triangulate_polygons to create a user-defined area, which we then use area_cut and intersection to subset the model to show the region inside or outside of that area. Finally, we explore volumetrics and its important settings to ensure that volume and mass analysis is performed correctly. The second series is on Advanced Gridding: Part One introduces krig_3d_geology’s Finite Difference Gridding option which provides a very flexible means to create a rotated rectangular 2D grid with complex cell size distributions. This video covers it basic functionality and is recommended for all users. Part Two continues Part One to add area_cut, polyline_spline and triangulate_polygons in order to create a grid that is confined to a region which closely conforms to the concave hull of a riverine dataset. It is recommended for advanced users and those needing more control over the areal extents of their models. Both video series are available on the public Training Videos page....

Stratigraphic Geology Training Video Series Posted

Aug 24, 2016 in Announcements, Training

We have just posted a new series of four training videos on modeling Stratigraphic Geology.  The first three cover rather basic topics related to the creation of stratigraphic geologic models, but the fourth and final video in the series tackles the more complex horizon_ranking module and how to use it to control hierarchy when you have intersecting stratigraphic horizons. All four videos are available on the public Training Videos page.
