Struct VerticalPerspective 

pub struct VerticalPerspective { /* private fields */ }

Near-sided vertical perspective projection onto a tangent plane.

Implementations

impl VerticalPerspective

pub fn new(center: GeoCoord, camera_height: f64) -> Self

Create a vertical perspective projection centered at center.

camera_height is the viewer height above the ellipsoid surface, in meters, and must be positive.

pub fn center(&self) -> GeoCoord

Projection center on the globe.

pub fn camera_height(&self) -> f64

Viewer height above the surface in meters.

pub fn radius(&self) -> f64

Earth radius used by the projection.

pub fn horizon_central_angle(&self) -> f64

Maximum visible central angle from the projection center, in radians.

pub fn project_checked(&self, geo: &GeoCoord) -> Option<WorldCoord>

Checked projection that rejects points beyond the visible horizon.

Trait Implementations

impl Clone for VerticalPerspective

fn clone(&self) -> VerticalPerspective

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for VerticalPerspective

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for VerticalPerspective

fn eq(&self, other: &VerticalPerspective) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Projection for VerticalPerspective

fn project(&self, geo: &GeoCoord) -> WorldCoord

Project a geographic coordinate to world space (meters).

fn unproject(&self, world: &WorldCoord) -> GeoCoord

Inverse-project world coordinates back to geographic.

fn scale_factor(&self, geo: &GeoCoord) -> f64

Local linear scale factor at the given geographic coordinate.

fn projection_bounds(&self) -> GeoBounds

The geographic bounding box of valid input for this projection.
