    Class Feature

    Feature – Abstracts and normalizes access to various Cesium/Scene feature types (Cesium3DTileFeature, Primitive, Entity).

    Provides unified API for identifier, type, color, show/hide, selectability, and dynamic property handling. Supports colorizing and clearing highlights for all supported entity types. Useful for consistent layer, selection, or property editing logic regardless of underlying Cesium/scene primitive type.

    The underlying Cesium or custom feature object (entity, primitive, or 3D tile feature).

    The property name used as primary identifier.

    getProperty(property) - Gets a dynamic property value, abstraction over Cesium feature types.

    colorize(color, keep=true) - Temporarily set feature highlight color, optionally keeping previous.

    clearColor() - Restore to the previous color.

    const feat = new Feature(tileFeature);
    feat.colorize(new Color(0,1,0), false);
    feat.show = false;
    console.log(feat.getProperty("HEIGHT"));
