Abstract: The invention relates to a computer-implemented method comprising the steps of: (S100) presenting a surface (S) comprising segments derived from volumetric data (VD) in a virtual reality user interface (6); (S200) presenting volumetric data (VD) in the virtual reality user interface (6); (S300) applying a signed distance field technique (SDF) to the segments in reference to the presented volumetric data (VD); (S400) adjusting at least one of the segments based on a result of applying the signed distance field technique (SDF) so that the presented surface data complies with the presented volumetric data (VD); and (S500) saving the adjusted at least one of the segments in a data file (DF) separately from a data file of the volumetric data (VD).

Abstract: A method for rendering an image in a virtual reality environment includes capturing volume data with a capturing device, storing the volume data in a memory, detecting a movement of a user with a tracking device, generating tracking data representing the movement of the user, setting rendering parameters for rendering the image, rendering the image from the volume data based on the rendering parameters, detecting a measure of the movement of the user based on the tracking data, and adapting the rendering parameters depending on the measure of the movement of the user. A system for rendering the image includes a tracking device, a communication interface, a memory, and a processor which sets rendering parameters, renders the image from the volume data based on the rendering parameters, detects a measure of the movement of the user, and adapts the rendering parameters depending on the measure of the movement.

Abstract: Linking within and among documents may include detecting at least one of intra-document and inter-document links present in a document; determining a document management project-specific document ID for the document; configuring a link resolution database with an entry for each detected link, each entry comprising link status, link direction, link type, source document link location information associated with the position of the link, and destination document link location information associated with a target viewing location in the destination document; and presenting the source document content in a user interface that overlays link annotations in a link annotation presentation layer over the presented source document content while associating the link annotations with a location of a link in the source document.

Abstract: Performing volume rendering in a virtual reality environment by applying an adapted Monte Carlo integration, grid accelerator-based view ray tracing, image filtering, and user-movement detected adapted frame compensation.
