Properties

maxElevation

maxElevation: number

Set maximum elevation to be rendered, values above sea level are positive.

minElevation

minElevation: number

Minimum elevation to be rendered, values beneath the sea level are negative.

Methods

evaluateClipPlanes

evaluateClipPlanes(camera: Camera, projection: Projection, elevationProvider?: ElevationProvider): ViewRanges

- Defined in @here/harp-mapview/lib/ClipPlanesEvaluator.ts:211
Compute near and far clipping planes distance.

remarks

Evaluation method should be called on every frame and camera clip planes updated. This is related to evaluator implementation and its input data, that may suddenly change such as camera position or angle, projection type or so. Some evaluators may not depend on all or even any of input objects, but to preserve compatibility with any evaluator type it is strongly recommended to update on every frame.

note

The camera clipping planes (near/far properties) aren't automatically updated via #evaluateClipPlanes() call, user should do it manually if needed.

Parameters
- camera: Camera
  
  The camera in use.
- projection: Projection
  
  The geo-projection currently used for encoding geographic data.
- Optional elevationProvider: ElevationProvider
  
  The optional elevation provider for fine tuned range calculation, taking into account terrain variability and unevenness.
Returns ViewRanges
