Top 3 C++ Visualisation Projects

DicomToMesh

1 409 6.4 C++

A command line tool to transform a DICOM volume into a 3d surface mesh (obj, stl or ply). Several mesh processing routines can be enabled, such as mesh reduction, smoothing or cleaning. Works on Linux, OSX and Windows.
Graphia

8 220 9.7 C++

A visualisation tool for the creation and analysis of graphs

Project mention: NetworkX – Network Analysis in Python | news.ycombinator.com | 2023-12-08

Export the graph to GML or to GraphML or to GraphViz DOT or to some other Graph format. BTW I recommend 3D graph visualization over 2D when possible, that is when you're exploring interactively as opposed to printing figures. The Graphia tool is the only FOSS tool for this purpose that I know of:
