The NVIDIA Scene Graph binary file (NBF) is a proprietary 3D data format developed by NVIDIA Corporation for its high-performance scene graph programming interface. It serves as a persistence format for complex three-dimensional scenes, enabling efficient loading and rendering within professional visualization, computer-aided design, and simulation environments. Although largely superseded by newer technologies like the SceniX engine, the format remains relevant for legacy data compatibility and carries minimal security risk as a non-executable binary.
