VSim facilitates the real-time exploration of highly detailed, three-dimensional computer models in both formal and informal educational settings. Beyond real-time interaction with three-dimensional content, this NEH-funded software offers two critical functions for academic use of interactive computer models: the narrative feature allows users to create linear presentations within the virtual space (akin to PowerPoint or Prezi within a three-dimensional world), and the embedded resource section allows users to embed within the virtual space annotations and links to primary and secondary resources about the modeled environment.

A software tool for the creation of 3D interactive environments. It may be used to model and interact with physical objects that currently or have previously existed in the real world, or create virtual environments that have not previously encountered. VirTool player software is available for Microsoft Windows, Apple MacOS X, Nintendo Wii and Microsoft Xbox 360.

It now exists today more as a commercial tool for business to include 3D experiences in various aspects of their activities.
