Provides projections which deform rectangular data blocks stored as textures into data coordinates. Provides common projection implementations such as polar, Mercator, and local tangent plane.
Interface Summary Interface Description InvertibleProjectionA complement interface
Projectionwhich provides the inverse transform for invertible projections.
ProjectionProvides a mapping from a texture coordinate to the lower left corner of the polygon which it should be mapped onto.
Class Summary Class Description FlatProjectionA simple projection which maps a texture onto a rectangle in physical coordinates with bottom-left corner at (minX, minY) and upper-right corner at (maxX, maxY). GenericProjectionAn alternative means of specifying a general projection. GeoReprojection LatLonProjectionA projection which maps a texture with data values spaced uniformly in lat/lon space onto a flat plane defined by the provided GeoProjection. PolarProjectionA projection which maps a texture into a circle or annulus (or an angular wedge of the above).
