Virtual reality streaming

A software program product stored in a computer-readable medium for providing a three-dimensional graphical computer model executable in at least one distributed cloud network server system comprising a plurality of servers, at least one model upload computer, and at least one user terminal computer, the software program product causing a processor to execute a method comprising:

• uploading the three-dimensional graphical computer model comprising spatial and visibility information data to a cloud network from the at least one model upload computer, the three-dimensional graphical computer model being composed from the spatial and visibility information data and partitioned into smaller cells;
• based on a virtual location of a user within the three-dimensional graphical computer model, displaying only parts of the three-dimensional graphical computer model that are visible from the virtual location on a terminal computer screen to the user, after the user connects to the cloud network with the at least one user terminal computer installed with an application configured for viewing the three-dimensional graphical computer model from said cloud server network;
• streaming parts of the three-dimensional graphical computer model and associated non-spatial information to the application on said at least one user terminal computer,
• wherein the three-dimensional graphical computer model is configured into a tree data structure that is queried with a visibility query with a radius limited to first visible objects from the at least one user terminal computer.

A cloud server network system a three-dimensional graphical computer, comprising:

• a plurality of servers;
• at least one model upload computer configured to upload a three-dimensional graphical computer model comprising spatial and visibility information data to a cloud network, the three-dimensional graphical computer model being composed from the data and partitioned into smaller cells;
• and
• at least one user terminal, installed with an application configured for viewing the three-dimensional graphical computer model from the cloud server network, configured to enable a user to connect to the cloud network, the at least one user terminal displaying, based on a virtual location of the user within the three-dimensional graphical computer model, only parts of the three-dimensional graphical computer model visible from said virtual location on a terminal computer screen to the user, parts of the three-dimensional graphical computer model and associated non-spatial information being streamed to the application on said terminal computer,
• wherein the three-dimensional graphical computer model is configured into a tree data structure that is queried with a visibility query with a radius limited to first visible objects from the at least one user terminal computer.
