Abstract

A system for advanced vector editing, comprising a vector analysis server that analyzes vector information, a routing calculation server that calculates routes from the vector information, and a rendering engine that produces visualizations from the routing information, and several methods for advanced vector editing in two- and three-dimensional visualizations.

First claim

What is claimed is:

1 . A system for advanced vector editing, comprising:
a vector analysis server stored and operating on a network-connected computing device; a routing calculation server stored and operating on a network-connected computing device; and a rendering engine stored and operating on a network-connected computing device. Wherein the vector analysis server analyzes a plurality of vector points and provides the results of analysis to the routing calculation server; Wherein the routing calculation server calculates routes based at least in part on the received vector analysis information, and provides the route information to the rendering engine; and Wherein the rendering engine forms visualizations based at least in part on the routing information received.

2 . The system of claim 1 , further comprising a database, wherein the database stores vector information and provides the stored information to the vector analysis server for use.

3 . The system of claim 2 , further wherein the database stores raster information.

4 . The system of claim 1 , further comprising a viewer, wherein the rendering engine provides the visualizations to the viewer.

5 . The system of claim 4 , wherein the viewer is a visual display screen, wherein the screen displays the visualizations for viewing by a human user.

6 . The system of claim 1 , further comprising a plurality of user input devices, wherein the user input devices allow a human user to interact with the visualizations.

7 . A method for advanced vector editing, comprising the steps of:
Positioning, using a rendering engine a cursor on a raster image displayed on a viewer; Calculating, using a routing calculation server, a radius around the cursor; Positioning the radius in contact with a vector path on a raster image; and Recalculating the vector path through the cursor location within the radius.

8 . The method of claim 7 , further comprising the step of resizing the radius prior to recalculating the vector path.

9 . The method of claim 7 , further comprising the step of selecting additional points prior to recalculating the vector path.

10 . The method of claim 9 , wherein the additional points are selected by a human user using a computer input device.

11 . The method of claim 9 , further comprising the step of recalculating the vector path through each of the selected points.

12 . The method of claim 7 , further comprising the steps of:
Determining, using a routing calculation server, a three-dimensional location from the 2-dimensional raster image; Determining a three-dimensional path; Recalculating the vector path according to the three-dimensional space; and Updating, using a rendering engine, the vector projection on the raster image.

13 . The method of claim 12 , further comprising the steps of:
Calculating, using a routing calculation server, the three-dimensional path according to epipolar geometry; Determining a new three-dimensional location based at least in part on the raster image and the three-dimensional path calculation; and Updating, using a rendering engine, the vector projection via the epipolar geometry.
