# Virtual Environment

**Virtual Environment** tool is an OntoGuiWeb module that supports the automatic and parametric generation of a virtual scene in VEB.js based on the content of an ontology module. Specifically, it is possible to set the following parameters:

* Root graph
* Address of the Virtual Env App, e.g. [VEB.js](https://virtualfactory.gitbook.io/vlft/tools/vebjs)
* Repo 3D, i.e. address of the [repository ](https://virtualfactory.gitbook.io/vlft/kb/instantiation/datarepo/remote#online-repository-for-binary-text-files)where the 3D models are stored
* Repo Animation, i.e. address of the [repository ](https://virtualfactory.gitbook.io/vlft/kb/instantiation/datarepo/remote#online-repository-for-binary-text-files)where the [animation sequences](https://virtualfactory.gitbook.io/vlft/kb/instantiation/animations#animation-sequence) are stored
* Input Animation, i.e. the [animation json](https://virtualfactory.gitbook.io/vlft/kb/instantiation/animations#schema) file to be loaded. If not defined, the application tries to build it from the name of the selected graph
* Input Env, i.e. the environment json file to be loaded. If not defined, the application tries to build it from the name of the selected graph
* Input Config, i.e. the configuration json file to be loaded. If not defined, the application tries to build it from the name of the selected graph
