- CoordinateTransform.h
- CoordinateTransform is a base class for transformations from "user interest" space to Vrui's navigational space. Classes derived from CoordinateTransform can be registered with Vrui's coordinate manager (see below), and are used to display coordinates in a coordinate system of interest to users of certain applications, e.g., geoid coordinates. The base class implements an identity transformation.
- OrthogonalCoordinateTransform.h

- CoordinateManager.h
- CoordinateManager allows Vrui applications to communicate their own units and coordinate systems to the Vrui toolkit. Vrui uses these definitions to provide an application-independent scale bar, and to display units and proper model coordinates (including non-linear mappings from navigation space) in measurements, e.g., those made with MeasurementTools.
- Viewer.h

- VRScreen.h
- VRScreen is a class representing fixed or device-mounted projection surfaces in VR environments. Together with viewers, screens describe how to display 3D scenes as (stereoscopic) images.
- WindowProperties.h

- ViewSpecification.h
- ViewSpecification is a class representing the visible space (frustum) of a VR display window, i.e., a combination of a viewer and a screen. View specifications are mostly used for view-dependent rendering and software frustum culling.
- VRWindow.h
- VRWindow is a class representing an OpenGL rendering window in a VR environment. VR windows tie together a viewer and a screen to create images of the 3D scene. VR windows contain methods to create monoscopic or stereoscopic images using several techniques.
