Struct GridScalarLayer 

pub struct GridScalarLayer {
    pub grid: GeoGrid,
    pub field: ScalarField2D,
    pub ramp: ColorRamp,
    /* private fields */
}

A flat georeferenced colour grid overlay.

Each grid cell is coloured by evaluating the ColorRamp at the cell’s normalised ScalarField2D value.

This layer participates in the standard MapState::pick system: a geographic pick query resolves to the grid cell via GeoGrid::cell_at_geo and returns the cell index and scalar value in the PickHit result.

Fields

grid: GeoGrid

Grid geometry.

field: ScalarField2D

Scalar field values.

ramp: ColorRamp

Colour transfer function.

Implementations

impl GridScalarLayer

pub fn new( name: impl Into<String>, grid: GeoGrid, field: ScalarField2D, ramp: ColorRamp, ) -> Self

Create a new grid scalar layer.

pub fn update_field(&mut self, data: Vec<f32>)

Replace the scalar field values (value-only update).
