Struct Elevation 

pub struct Elevation { /* private fields */ }

Height above the surface, expanded into contact, key and ambient shadows.

A small dark contact shadow anchors the object, a medium key shadow follows the light direction and a wide faint ambient shadow suggests occlusion. Sigmas and offsets grow linearly with height, while opacity falls off smoothly.

use motion_core::{Color, Elevation, NodeModifiers, Rect};
let card = Rect::new(0.0, 0.0, 80.0, 50.0).fill(Color::WHITE);
let raised = card.elevated(Elevation::shadow(12.0)?);

Implementations

impl Elevation

pub const MAX_HEIGHT: f64 = 1024.0

Largest accepted height in local units.

pub fn shadow(height: f64) -> Result<Self, ValidationError>

Creates a downward-falling black shadow stack for a finite height in 0..=1024.

pub fn direction(self, direction: Vector2) -> Result<Self, ValidationError>

Sets the direction the shadow falls; the vector is normalized.

pub fn color(self, color: Color) -> Self

Sets the encoded-sRGB shadow color; its alpha scales every layer.

pub fn height(self) -> f64

The elevation in local units.

pub fn layers(self) -> Vec<ShadowLayer>

Contact, key and ambient layers; empty at zero height.

pub fn apply(self, source: Node) -> Node

Draws the layers behind a single untouched source snapshot.
