Systems and methods for efficient point cloud visualization based on a hybrid rendering of data points and meshes

A system comprising:

• one or more processors configured to:
• receive a file comprising a plurality of data points that are distributed non-uniformly in three-dimensional (“3D”) space to represent a 3D environment at a first level of detail;
• define each construct of a set of constructs with a singular set of values based on two or more sets of values from two or more different data points of the plurality of data points, wherein the set of constructs represent the 3D environment at a second level of detail that is less than the first level of detail;
• generate a complete visualization of the 3D environment at the second level of detail by rendering the set of constructs instead of the plurality of data points;
• select a part of the complete visualization at which to increase detail from the second level of detail to the first level of detail;
• and
• increase the detail at the part of the complete visualization by rendering a set of the plurality of data points that generate the part of the complete visualization at the first level of detail.

A non-transitory computer-readable medium, storing a plurality of processor-executable instructions to:

• receive a file comprising a plurality of data points that are distributed non-uniformly in three-dimensional (“3D”) space to represent a 3D environment at a first level of detail;
• define each construct of a set of constructs with a singular set of values based on two or more sets of values from two or more different data points of the plurality of data points, wherein the set of constructs represent the 3D environment at a second level of detail that is less than the first level of detail;
• generate a complete visualization of the 3D environment at the second level of detail by rendering the set of constructs instead of the plurality of data points;
• select a part of the complete visualization at which to increase detail from the second level of detail to the first level of detail;
• and
• increase the detail at the part of the complete visualization by rendering a set of the plurality of data points that generate the part of the complete visualization at the first level of detail.
