Struct openrailwaymap_exporter::app3d::Projection

pub struct Projection { /* private fields */ }

The Projection resource is responsible for converting geographical coordinates (latitude and longitude) to view coordinates, taking into account the view dimensions and the bounding box of a given RailwayGraph.

Implementations

impl Projection

pub fn new(view_width: f64, view_height: f64) -> Self

Creates a new Projection resource with the specified view dimensions.

Arguments

• view_width - The width of the view in pixels.
• view_height - The height of the view in pixels.

pub fn set_bounding_box(&mut self, min_coord: Coord, max_coord: Coord)

Sets the bounding box of the Projection resource based on the minimum and maximum coordinates.

Arguments

• min_coord - The minimum coordinate of the bounding box.
• max_coord - The maximum coordinate of the bounding box.

pub fn project(&self, coord: Coord) -> Option<Vec3>

Projects the given geographical coordinate to a view coordinate.

Arguments

• coord - A geographical coordinate (latitude and longitude).

Returns

• Option<Vec3> - A view coordinate as a 3D vector if the bounding box is set, or None otherwise.
