SUN-SHADOW SIMULATION IN A GEOSPATIAL SYSTEM
First Claim
1. A computer implemented method for displaying a sun and shadow simulation in a three-dimensional system, comprising:
- displaying, using a three-dimensional (3D) graphics application, a 3D view of a real world scene on a display device;
installing a plug-in into the 3D graphics application;
receiving input from a user defining, for the plug-in, a calendar period comprising a month, day, and year;
displaying, in the 3D view, a timeline arc, wherein the calendar period defines a radius of the arc, and a starting endpoint and a stopping endpoint of the timeline arc define an interval of time during the calendar period;
displaying, on the timeline arc, a timeline slider that indicates a time of day; and
displaying, in the 3D view, a visualization of shadows cast by a sun on objects in the 3D view, wherein a position of the sun in the visualization is based on the calendar period and the time of day.

Abstract
A method, apparatus, and article of manufacture provide the ability to display a sun and shadow simulation in a 3D system. A 3D view of a real world scene is displayed, using a 3D graphics application, on a display device. A plug-in is installed into the application. A calendar period (e.g., a month, day, and year) is defined by the user. A timeline arc is displayed with the calendar period defining a radius of the arc, and starting stopping endpoints of the timeline arc defining an interval of time during the calendar period. A timeline slider is displayed on the arc that indicates a time of day within the calendar period. A visualization is displayed, in the 3D view, of shadows cast by a sun on objects in the 3D view. A position of the sun is based on the calendar period and the time of day.
