Struct HillshadeLayer 

pub struct HillshadeLayer { /* private fields */ }

Backend-owned hillshade styling parameters.

These parameters are consumed by renderers when drawing terrain. The layer itself does not fetch tiles or generate meshes; it only contributes shading state to the frame, similar to a style layer.

Implementations

impl HillshadeLayer

pub fn new(name: impl Into<String>) -> Self

Create a hillshade layer with conservative MapLibre-like defaults.

pub fn highlight_color(&self) -> [f32; 4]

RGBA colour used for lit slopes.

pub fn shadow_color(&self) -> [f32; 4]

RGBA colour used for shadowed slopes.

pub fn accent_color(&self) -> [f32; 4]

RGBA accent colour mixed onto steeper terrain.

pub fn illumination_direction_deg(&self) -> f32

Illumination direction in degrees clockwise from north.

pub fn illumination_altitude_deg(&self) -> f32

Illumination altitude in degrees above the horizon.

pub fn exaggeration(&self) -> f32

Vertical emphasis applied to the hillshade effect only.

pub fn set_highlight_color(&mut self, color: [f32; 4])

Set highlight colour.

pub fn set_shadow_color(&mut self, color: [f32; 4])

Set shadow colour.

pub fn set_accent_color(&mut self, color: [f32; 4])

Set accent colour.

pub fn set_illumination_direction_deg(&mut self, direction_deg: f32)

Set illumination direction in degrees clockwise from north.

pub fn set_illumination_altitude_deg(&mut self, altitude_deg: f32)

Set illumination altitude in degrees above the horizon.

pub fn set_exaggeration(&mut self, exaggeration: f32)

Set hillshade exaggeration multiplier.

pub fn effective_params(&self) -> HillshadeParams

Return the effective renderer-facing parameter snapshot.
