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...

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...

Free 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...

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...

Volumetrics 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...

Modeling 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...
