Abstract

A rendering system that includes at least one processor configured to receive a plurality of data points, receive at least one priority assignment, assign at least one priority value to the plurality of data points based on the at least one priority assignment, and render the plurality of data points based on the at least one priority value.

First claim

The invention claimed is:

1 . A rendering system comprising at least one rendering processor configured to:
receive a plurality of data points in a point cloud, each of the plurality of data points represented by positional and color data; render all the plurality of data points if rendering processing capacity is sufficient; receive at least one priority assignment comprising a distance from a user and angle from the user's line of sight; assign at least one priority value to each of the plurality of data points based on the at least one priority assignment; if rendering processing capacity is insufficient, then render the plurality of data points based on the at least one priority value; and while remaining rendering processor capacity is below a minimum processing capacity, repeating the steps of:
determining the remaining rendering processor capacity;
readjusting at least one priority value to the plurality of data points based on the remaining rendering processor capacity and the at least one priority assignment; and
rendering the plurality of data points based on the readjusted at least one priority value.

2 . The rendering system of claim 1 , wherein the at least one priority assignment further comprises at least one object of interest.

3 . The rendering system of claim 1 , wherein the at least one priority assignment further comprises at least one location of interest.

4 . The rendering system of claim 1 , wherein the at least one priority assignment further comprises color contrast.

5 . The rendering system of claim 1 , wherein the at least one priority assignment further comprises brightness.

6 . The rendering system of claim 1 , further comprising a priority assignment source configured to transfer the at least one priority assignment to the at least one processor.

7 . The rendering system of claim 1 , wherein the priority assignment source comprises a safety system.

8 . The rendering system of claim 7 , wherein the safety system is configured to identify and generate features corresponding to hazards.

9 . The rendering system of claim 8 , wherein the hazards may be at least one of: likelihood of negative event occurring, severity of impact and difficulty of detection.

10 . A method of rendering, comprising:
providing a rendering system comprising at least one rendering processor configured for executing computer instructions implementing the method of rendering including a priority algorithm and a rendering algorithm; receiving a plurality of data points, each of the plurality of data points represented by positional and color data; render all the plurality of data points if rendering processing capacity is sufficient; receiving at least one priority assignment comprising a distance from a user and angle from the user's line of sight; assigning at least one priority value to each of the plurality of data points based on the at least one priority assignment; if rendering processing capacity is insufficient, then rendering the plurality of data points based on the at least one priority value; and while remaining rendering processor capacity is below a minimum processing capacity repeating the steps of:
det ermining the remaining rendering processor capacity;
readjusting at least one priority value to the plurality of data points based on the remaining rendering processor capacity and the at least one priority assignment; and
rendering the plurality of data points based on the readjusted at least one priority value.

11 . The method of rendering according to claim 10 , wherein the rendering system further comprises:
a point cloud data source configured to send the plurality of data points to the rendering processor; and a priority assignment source configured to send the at least one priority assignment to the rendering processor.

12 . The method of rendering according to claim 10 , wherein the at least one priority assignment further comprises at least one of the following: an object of interest and a location of interest.

13 . The method of rendering according to claim 10 , wherein the at least one priority assignment further comprises at least one of: color contrast and brightness.

14 . The method of rendering according to claim 10 , further comprising a priority assignment source configured to transfer the at least one priority assignment to the at least one processor.

15 . The method of rendering according to claim 14 , wherein the priority assignment source comprises a safety system configured to identify and generate features corresponding to hazards.

16 . The method of rendering according to claim 15 , wherein the hazards may be at least one of: likelihood of negative event occurring, severity of impact and difficulty of detection.
