Struct FlatTileView 

pub struct FlatTileView {
    pub target_world: WorldCoord,
    pub distance: f64,
    pub pitch: f64,
    pub yaw: f64,
    pub fov_y: f64,
    pub viewport_width: u32,
    pub viewport_height: u32,
}

Camera parameters needed to select flat raster tiles for a pitched perspective map view.

The selection algorithm starts from the conservative axis-aligned visible_tiles result computed from the world-space viewport bounds, then filters that set against the sampled ground footprint of the actual screen frustum. This keeps coverage correct while avoiding severe tile over-selection at steep pitch angles where the visible ground forms a thin, rotated trapezoid rather than a broad rectangle.

Fields

target_world: WorldCoord

Camera target in Web Mercator world coordinates (meters).

distance: f64

Camera orbit distance in meters.

pitch: f64

Camera pitch in radians.

yaw: f64

Camera yaw in radians.

fov_y: f64

Vertical field of view in radians.

viewport_width: u32

Viewport width in logical pixels.

viewport_height: u32

Viewport height in logical pixels.

Implementations

impl FlatTileView

pub fn new( target_world: WorldCoord, distance: f64, pitch: f64, yaw: f64, fov_y: f64, viewport_width: u32, viewport_height: u32, ) -> Self

Construct flat-view selection parameters.

Trait Implementations

impl Clone for FlatTileView

fn clone(&self) -> FlatTileView

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FlatTileView

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

Formats the value using the given formatter.

impl PartialEq for FlatTileView

fn eq(&self, other: &FlatTileView) -> 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.
