Previously the Modeling, Virtual Environments, and Simulation (MOVES) Institute at the Naval Postgraduate School in Monterey, California managed and supported delta3d.

Delta3d is unique, because it offers features specifically suited to the Modeling, Simulation and DoD communities, such as the High Level Architecture (HLA), After Action Review (AAR), large scale terrain support, and SCORM Learning Management System (LMS) integration.

The Delta3D engine renders using the Open Graphics Library (OpenGL) that imports a whole list of diverse file formats (.flt, .3ds, .obj, even more so).

Delta3d is developed and tested on Windows XP using Microsoft Visual Studio, OS X using Clang, as well as Linux using GCC.

Simulation Core, commonly referred to as SimCore, is a "collaborative" implementation of delta3d functionality — providing the "base" capabilities for an MMORPG application using delta3d.

The first version of SimCore was developed as part of the Deployable Virtual Training Environment (DVTE) project for USMC which started in 2006.
