ICanvasTransform

Description

interface Tinman.Terrain.Mapping.ICanvasTransform

Derived from

IMapTransform

Base interface for classes that provide different coordinate spaces and transformations between them.

The methods of this interface refer to the following coordinate space definitions:

  • Canvas space:
    Coordinates that refer to locations on a canvas, defined by the implementing class (for example: screen viewport coordinates, image pixel coordinates, unfolded cubemaps).

  • Dataset space:
    Coordinates that refer to samples in a rectangular or cubemap dataset, see IMapTransform.DatasetSpace. For rectangular datasets, the Z-coordinate of cubemap coordinates will always be 0 and the cubemap face will always be CubemapFace.NegZ.

  • Map space:
    Coordinates that refer to locations in a geo-referencing coordinate system, see IMapTransform.MapSpace.
