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.

The Release of 64-bit Earth Volumetric Studio 2016.8

Aug 16, 2016 in Announcements, New Releases

Earth Volumetric Studio 2016.8 is now available to download. I hope that you will forgive my being a bit long winded in this announcement, as I feel this is truly a momentous occasion for C Tech and our customers. C Tech has been in business now for 27 years and I have personally been involved with 3D modeling and visualization for 39 years. I saw the need for Environmental Visualization System (the original EVS) in 1989 and we had our first commercial Unix-based software available in 1990. However, in 1994 when Windows NT was released we were ready with a product for Windows and our market took off. Over the next 22 years our software grew and evolved into a line of products that included the 4DIM Player, EVS for ArcView, EVS-Standard, EVS-Pro, MVS and the EnterVol for ArcGIS product line. When we started on EnterVol over 5 years ago we tried to step back and not be restricted by backwards compatibility with EVS & MVS and there were some interesting advances that came from that. At the same time that EnterVol began we started brainstorming the next generation of our EVS product line, which brings us to today’s announcement. For those of you that recognize that today we offer only two primary products: Earth Volumetric Studio and EnterVol, you might wonder why our product line has shrunk. The answer is our users. We listened to the frustration of users with EVS-Standard or Pro who needed MVS features but couldn’t convince their management to upgrade. We see our EnterVol suite of products as our entry level software and Studio as our flagship. We wanted all of our EVS & MVS users to be able to take advantage of all of the amazing features we were developing in Studio, so about one year ago, we decided to offer only a single version of Earth Volumetric Studio which would be a super-set of MVS functionality. Nearly 4 years ago we reached out to a select group of users, we nicknamed the MVS Influencers. They were chosen, you might say, because they were the proverbial squeaky wheels. These were the users that our tech support group heard from a lot. We wanted to make sure that our next-gen technology wasn’t developed in a vacuum, and to that end, you have seen us put out quite a few Candidate Releases of Earth Volumetric Studio as we have striven to implement our ideas and theirs. Today also marks the end of Candidate Releases. There is a part of me that would like to say that Earth Volumetric Studio version 2016.8 is the best software that we could possibly deliver to our customers. But if I waited until we could make it no better, it would never be ready. We are a creative bunch and I assure you that as good as it is today (and it is amazing), it will only continue to improve with each future release. We have so many great ideas, that it is a hard task just prioritizing what we should tackle next. It is time to explain why this release is such a big deal. This is the first release of Earth Volumetric Studio and it is the first native 64-bit application we have offered. As the development team...

Update on Animating Web-Based Models

May 12, 2016 in Announcements

I wanted to post a quick correction to my announcement on 3D Publishing to the web.  I started writing that post weeks before it was released because we were working on the examples for our website.  During that time, Sketchfab shared with us a solution for animating web-based models.  Unlike our 4DIM and PDF animations which are frame-based, the Sketchfab animations must have a time duration assigned to each VRML frame.  The first example showing the railyard has 8 frames which flip on 5 second intervals.   We’ve been told that Sketchfab will soon add the ability to specify frames vs. times which will make things even better.
