  • Patent number: 12200030
    Abstract: Systems and methods are provided for processing data received at a server node from a first client node. The method includes generating selected data by removing one or more redundant sample points from data received from the first client node. A redundant sample point represents a sample point, of the data received from the first client node, that can be regenerated from one or more adjacent sample points, of the data received from the first client node, using interpolation. The method includes generating, from the selected data, graphical data at multiple fidelity levels including at least one of low-fidelity graphical data, medium-fidelity graphical data and high-fidelity graphical data. The method includes sending at least one of the low-fidelity graphical data, the medium-fidelity graphical data and the high-fidelity graphical data to a second client node in dependence on a current zoom level of the second client node.

  • Patent number: 11799927
    Abstract: Systems and methods are provided for processing data received at a server node from a first client node. The method includes generating filtered data by removing one or more erroneous sample points from the data received from the first client node. The one or more erroneous sample points represent one or more sample points determined to be unintentionally entered at the first client node. The method includes generating selected data by removing one or more redundant sample points from the filtered data. The method includes generating graphical data at multiple fidelity levels from the selected data. The method includes receiving a current zoom level of the second client node displaying a portion of a shared virtual workspace that includes a digital asset associated with the graphical data. The method includes sending the generated graphical data to the second client node in dependence on the current zoom level.

  • Patent number: 10705786
    Abstract: A collaboration system including a spatial event map that can be published as an electronic document by a collaboration server and consumed by a consuming workstation. The electronic document is self-contained, and includes a viewer that has a module for rendering each of the graphical target types in the workspace onto a screen space. The system includes a server-side data processor that maintains the spatial event map which locates events in a workspace. The spatial event map includes a log of events, entries in the log having a location of a graphical target of the event in the workspace and a time.
