Systems and methods for optimized streaming of three-dimensional content based on a pre-culled segmentation of the three-dimensional content

A streaming system comprising:

• one or more hardware processors configured to:
• receive three-dimensional (3D) content comprising a plurality of primitives defined in a 3D space;
• define a set of tiles comprising two-dimensional (2D) planes in the 3D space that surround the 3D content from different sides and that are a specified distance away from the plurality of primitives;
• segment a different set of primitives from the plurality of primitives to a different tile of the set of tiles based on the different set of primitives being positioned within boundaries of the 2D plane of the different tile;
• filter the different set of primitives segmented to each tile of the set of tiles, wherein filtering the different set of primitives that are segmented to a particular tile of the set of tiles comprises differentiating a first subset of primitives from the different set of primitives that are visible through the 2D plane of the particular tile from a second subset of primitives from the different set of primitives that are not visible through the 2D plane of the particular tile;
• receive a request to view the 3D content from a particular field-of-view;
• retrieve one or more tiles from the set of tiles that span the particular field-of-view;
• and
• stream the first subset of primitives that are visible from each tile of the one or more tiles in response to the request without the second subset of primitives that are not visible from each tile of the one or more tiles.

A non-transitory computer-readable medium storing instructions that, when executed by one or more processors of a streaming system, cause the streaming system to perform operations comprising:

• receiving three-dimensional (3D) content comprising a plurality of primitives defined in a 3D space;
• defining a set of tiles comprising two-dimensional (2D) planes in the 3D space that surround the 3D content from different sides and that are a specified distance away from the plurality of primitives;
• segmenting a different set of primitives from the plurality of primitives to a different tile of the set of tiles based on the different set of primitives being positioned within boundaries of the 2D plane of the different tile;
• filtering the different set of primitives segmented to each tile of the set of tiles, wherein filtering the different set of primitives that are segmented to a particular tile of the set of tiles comprises differentiating a first subset of primitives from the different set of primitives that are visible through the 2D plane of the particular tile from a second subset of primitives from the different set of primitives that are not visible through the 2D plane of the particular tile;
• receiving a request to view the 3D content from a particular field-of-view;
• retrieving one or more tiles from the set of tiles that span the particular field-of-view;
• and
• streaming the first subset of primitives that are visible from each tile of the one or more tiles in response to the request without the second subset of primitives that are not visible from each tile of the one or more tiles.
