When using Carmenta Engine, there are times in which you want to be more specific about your visualization. Perhaps your visualization is only suitable for certain type of observers, at certain zoom levels or at certain times of the day. These are what we refer to as dynamical runtime condition variables. They exist as a set of UpdateAttributes inside the View class. There is a set of predefined variables but it’s also possible to add custom variables.
Custom objects are a flexible plugin mechanism in Carmenta Engine for integrating customized operations in a regular map configuration. More functionality is added in new Carmenta Engine versions to make this integration more seamless compared to the built-in objects. In this guide, we will focus on the custom dataset use case, for retrieving a customized DataSetInfo, and dynamically instantiating the dataset based on a file on disk.
Through its tactical extension, Carmenta Engine provides support for visualization and editing of tactical symbols and graphics according to widely used military standards. Currently, the supported standards are MIL-STD-2525 versions B, C and D, as well as NATO App-6 versions B, C and D.
Using a few well-chosen feature attributes, it becomes easy to visualize objects from an already existing dataset as a tactical overlay on a background map. Carmenta Engine’s standard tools have full support for dynamically creating and modifying tactical features directly on the map.
In this article, we will cover the basic layer chain which can be used to display a tactical overlay, as well as how to control the symbol modifiers from Feature attributes.
