Systems and methods for signal-based point cloud representation

An encoding system comprising:

• one or more hardware processors configured to:
• receive a file that is defined with a plurality of data points that collectively produce a three-dimensional (“3D”) scene, wherein each data point of the plurality of data points is defined with x, y, and z positional coordinates and one or more visual characteristics;
• map the x, y, and z positional coordinates and the one or more visual characteristics of each data point from the plurality of data points to one or more frequency domains based on differing frequencies with which the x, y, and z positional coordinates and the one or more visual characteristics are defined in the plurality of data points;
• generate a waveform as a fluctuating signal that fluctuates according to the differing frequencies representing the x, y, and z positional coordinates and the one or more visual characteristics of the plurality of data points in the one or more frequency domains, wherein the waveform encodes the x, y, and z positional coordinates and the one or more visual characteristics of the plurality of data points with fewer bits than the file;
• and
• transmitting the fluctuating signal over a data network in response to a request from a remote device for the 3D scene.

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

• receiving a file that is defined with a plurality of data points that collectively produce a three-dimensional (“3D”) scene, wherein each data point of the plurality of data points is defined with x, y, and z positional coordinates and one or more visual characteristics;
• mapping the x, y, and z positional coordinates and the one or more visual characteristics of each data point from the plurality of data points to one or more frequency domains based on differing frequencies with which the x, y, and z positional coordinates and the one or more visual characteristics are defined in the plurality of data points;
• generating a waveform as a fluctuating signal that fluctuates according to the differing frequencies representing the x, y, and z positional coordinates and the one or more visual characteristics of the plurality of data points in the one or more frequency domains, wherein the waveform encodes the x, y, and z positional coordinates and the one or more visual characteristics of the plurality of data points with fewer bits than the file;
• and
• transmitting the fluctuating signal over a data network in response to a request from a remote device for the 3D scene.
