Description

3DHOP is a free JavaScript framework for displaying 3D models online. The interface can be customised in a variety of ways allowing users to have various degrees of control over the models and access to tools (hotspots, measurement, point picking, sectioning).

Using JavaScript, it requires no specialist server set up although files must be converted to the Nexus (NXS or compressed NXZ) format for display. A tool for converting files from PLY and OBJ format is freely available.
