METHOD AND SYSTEM FOR RENDERING 3D MODELS IN A BROWSER USING DISTRIBUTED RESOURCES Russian patent published in 2020 - IPC G06T15/00 

FIELD: image processing means.

SUBSTANCE: invention relates to means of performing 3D rendering (visualization) on user configurations in conditions of limited computational resources. At least one three-dimensional model is obtained on the server. Each object in the three-dimensional model is broken down into an array of triangles and placed into the objects storage by its unique identifier. A spatial index is formed in the database of all objects from the obtained three-dimensional model. A visibility pyramid is formed, which consists of a predetermined number of cubes and a request is sent to the server to obtain a list of objects included in the given cubes. A list of objects for visualization is formed by primary rejection of three-dimensional objects according to the method of clipping by entering into the requested cubes at the server side based on the spatial index of each object. Objects are sorted from the found list from the larger to the lower based on a predetermined criterion. An array of unique identifiers of the sorted objects is sent to the user's browser from the server. Objects are rendered based on unique identifiers obtained at the previous step.

EFFECT: high speed of processing and visualizing 3D objects.
