The Earth Volumetric Studio Environment

If you have not already done so, start EVS at this time. To start EVS, double-click on the Earth Volumetric Studio icon located in the programs listing of your Windows Start Menu. Choose New Application and if you have not changed the default settings, EVS will open to show the following subwindows.

Each window can be resized, moved or undocked from the main window. This makes it easy to optimally use multiple monitors.

 

Visual Programming

EVS uses a visual programming paradigm. The Earth Volumetric Studio application has several primary subwindows. Each can be moved, resized, undocked or stacked with tabs.

• The viewer is in the lower left. It will be black (or whatever color you set as default) and empty until you have an application that has run.the viewer (left) is the Application Overview window. It automatically resizes to show you a thumbnail view of your application. It allows you to navigate, zoom and pan your application.
  • On the left side of the viewer is the [Table of] Contents (model tree) that provides quick control of objects in your view.
• In the upper right are three tabbed windows:

1. The Information window displays the outputs from several EVS functions including probing, distance measurement and modules like statistics and volumetrics.
2. Packaged Files allows you to see and manage the data files referenced in the application that have been packaged into the application. Doing this ensures that this application will always create the same results even if the master file(s) are revised. It also makes the application (.evs file) completely portable and able to standalone.
3. The Application Overview window automatically resizes to show you a thumbnail view of your application. It allows you to navigate, zoom and pan your application.

• Above the viewer are the Modules which are arranged in 17 sublibraries. The easiest way to find and use a module is to type the first 1-2 letters of the module name. The list will show only those modules that include those letters. You can then instance (copy to your application) any module by selecting it and hitting ENTER, double clicking, or dragging it to the Application.

• The Application window is the in the center. This is where you will add the modules and interconnect them to create a custom application to perform your required tasks
• Below it is the Output Log which provides useful information when modules run. We highly recommend keeping this window visible.
• The Properties window is where you can set the parameters for each module. By double clicking on any module (or connection) in your application, you can set its properties.
• Please see: Home & Options Tabs Basics for details on those elements of the EVS Environment.

The Application area is the workspace where you use the modules to build a custom application. The Modules libraries are like a toolbox, in that there are many different tools that serve different purposes, but cannot be used until they are taken out of the toolbox. Similarly, the Application window is similar to a workbench: it is the place where the tools are used to create models. Most modules in the library have input and/or output ports. These are colored regions (ports) on the modules which represent the pipelines through which data flows to and from each module. A collection of modules that have their ports connected by pipelines comprise an EVS Application (.evs file).
