Getting Familiar With The EVS Environment

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. 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 upper left. It will be a faded black (or whatever color you set as default) and empty until you have an application that has run.

• Below 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.

• To the right of the Application Overview window are the Modules which are listed in 19 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 expand to 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.

• 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.

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).
