3DHOP (3D Heritage Online Presenter) is an open-source framework for the creation of interactive Web presentations of high-resolution 3D models, oriented to the Cultural Heritage field. 3DHOP target audience ranges from the museum curators with some IT experience to the experienced Web designers who want to embed 3D contents in their creations, from students in the CH field to small companies developing web applications for museum and CH institutions.

HexaLab is a WebGL application for real time visualization, exploration and assessment of hexahedral meshes. This visualization tool targets both users and scholars. Practitioners who employ hexmeshes for Finite Element Analysis, can readily check mesh quality and assess its usability for simulation. Researchers involved in mesh generation may use HexaLab to perform a detailed analysis of the mesh structure, isolating weak points and testing new solutions to improve on the state of the art and generate high quality images. The system also offers immediate access to a repository containing all the publicly available meshes produced with the most recent techniques for hex mesh generation.

Nexus is a c++/javascript library for creation and visualization of a batched multiresolution 3D model structure. It is able render interactively very large 3D models efficiently in OpenGL and on the web.

OpenLIME (Open Layered IMage Explorer) is an open-source JavaScript library for the efficient display of scalable high-resolution relightable images.
It natively supports BRDF and RTI datasets, and can be easily extended for other multi-channel raster datasets, such as hyper spectral imaging or other reflectance modeling. Input data can be combined in a multi-layer visualization system using opacity and blending modes, and interactive lenses. OpenLIME is jointly developed by CRS4 Visual and Data-intensive Computing Group.

RelightLab is an open-source application for the creation or relightable images (RTI: Reflectance Transformation Imaging), using a collection of images sharing a common viewpoint and different light direction. It supports legacy formats such as .ptm and .rti, as well as a newer format suitable for efficient web visualization (through the lib OpenLime). It replaces the RTIBuilder outdated and unsupported Java application, and add new features, such as normal computation, lights 3d geometry, etc.
