TruView data sets are used for sharing 3D scanner data via an intuitive, easy-to-use interface with no CAD or 3D skills required. These datasets can contain multiple Sitemaps from a project, 3D scanner point cloud data, imagery data, design model visualizations, GeoTags, associated files, and markups (measurements and various types of annotations). The data sets consist of individual TruView setups/positions which are 360 degree spherical panoramic views of the data and which typically represent 3D scanner positions for static scanner, but which can also be virtually created at any user-defined point in 3D space with Leica Cyclone software prior to publishing the data set.
