Struct InstancedColumnLayer 

pub struct InstancedColumnLayer {
    pub columns: ColumnInstanceSet,
    pub ramp: ColorRamp,
    /* private fields */
}

An instanced column overlay layer.

Renders a collection of box or cylinder columns anchored to geographic positions. Each column has independent height, width, colour, and pick ID. Renderers use GPU instancing for efficient draw of large datasets.

Fields

columns: ColumnInstanceSet

Column instances.

ramp: ColorRamp

Fallback colour ramp for columns without per-instance colour.

Implementations

impl InstancedColumnLayer

pub fn new( name: impl Into<String>, columns: ColumnInstanceSet, ramp: ColorRamp, ) -> Self

Create a new instanced column layer.

pub fn set_columns(&mut self, columns: ColumnInstanceSet)

Replace the column set.
