Web WorldWind has a rich and growing set of shapes to choose from: Placemark (class Placemark) Displays an image with an optional label at any geographic position and altitude. Any application, proprietary or other, can use NASA. As a result, the best virtual globe that can be used are the ones written in Java, or better JavaScript and free and open source. Shapes Shapes represent the information other than surface imagery that you display on the globe. It is elemental technology allowing others to see 'their' spatial data in the native context of Earth or any other planet for which there is data. This shape uses a SurfacePolyline when drawing on 2D globes and this shape's useSurfaceShapeFor2D is true.Ĭlears this shape's data cache. NASA World Wind is virtual globe technology provided as an Application Programming Interface-Centeric (API-Centric) Software Development Kit (SDK). A curtain extends from the line formed by the path positions to the ground. ![]() They use the interior and outline attributes of ShapeAttributes but do not use the image attributes.Ī path displays as a curtain if its extrude property is true. Paths have separate attributes for normal display and highlighted display. If the latter, the path positions' altitudes are ignored. ![]() Paths conform to the terrain if the path's followTerrain property is true.Īltitudes within the path's positions are interpreted according to the path's altitude mode, which can be one of the following: The path is drawn between inputpositions to achieve a specified path type, which can be one of the following: Represents a line, curve or curtain between specified positions.
