EM starts from here


During data collection process, you can draw an Extended Matrix using any kind of support (digital or not). 

However, in order to connect EM with Blender, a specific digital format of the EM graph (.graphml format) is required. As a response to this need, it is recommended to download yED, a free (non-open source) software useful for producing digital graph.

EM is fully developed for Blender, therefore it is required to install Blender as well to establish a connection between EM and 3D models.

Online sharing

The DHILab of the CNR-ISPC of Rome has developed a web-app (EMviq), based on the Aton framework, that allows you to: 

Aton is an Open Source Web3D/WebXR app which is suitable for enhancement and disclosure purposes.

EMviq, which inherits all the features of Aton, includes EM representation functionality and has been developed for scientific purposes.

In order to share online your 3D reconstructions you need to install both Aton 3.0 and EMviq (click on the buttons below and follow the instructions).

Other recommended tools
