![]() Once a location is clicked on, the user jumps to that location where they can rotate, zoom, measure features, and annotate within the view. The user is typically provided with a “site map” that has hyperlinks to individual scan locations. TruView is a web-based point cloud viewer that allows users to view and measure point cloud datasets online. Leica Cyclone offers two free point cloud viewing options. Geomagic Qualify only opens Geomagic WRP files. Users can measure distances, annotate, create reports, and modify data sets. Geomagic Review offers the ability for users to view inspection results created by Geomagic Qualify. It also offers standard reporting options as well as the ability to publish 3D scan models embedded in HTML pages. Rapidform Explorer offers support for a wide variety of formats including standard formats such as ASCII, OBJ, and DXF and numerous scanner proprietary formats. In addition to basic 3D viewing and measurements, Explorer also offers area and volume calculations for mesh and CAD models. Rapidform Explorer is a free data viewer that supports 3D viewing and measurement capabilities for numerous point cloud, mesh, and CAD formats. IMView also imports standalone mesh files including OBJ, WRL, PLY and others however all measurement functionality is removed and the software only acts as a free viewer with basic 3D viewing capabilities. In IMView, users can calculate basic measurements including distance, radii, angles, and cross-sections and can also generate inspection reports in PDF, Word, Excel or HTML formats. Users can export and distribute IMInspect projects which can include point cloud, mesh, or CAD datasets which can then be viewed in IMView. IMView is the free viewer provided by Polyworks and is optimized for viewing projects generated from the IMInspect module available in the commercial version of the Polyworks software.

Below is a list of common free point cloud viewers followed by a quick comparison chart. ![]() These packages vary widely in the types of point cloud data sets that are supported, many packages only support proprietary formats, and the advanced functionality beyond basic point cloud viewing and manipulation. Instead, software packages used to edit and process point cloud datasets typically make free data viewers available that are used for viewing and manipulating point clouds. Point clouds are a unique data type that are not yet widely supported in typical 3D modeling or CAD packages. Point cloud data sets, particularly those produced by large terrestrial surveys, can be very large often containing millions of points. Free data viewers for point cloud datasets ![]()
