/**
 * A procedural cone-shaped geometry.
 *
 * Typically, you would:
 *
 * 1. Create a ConeGeometry instance.
 * 2. Generate a {@link Mesh} from the geometry.
 * 3. Create a {@link MeshInstance} referencing the mesh.
 * 4. Create an {@link Entity} with a {@link RenderComponent} and assign the {@link MeshInstance} to it.
 * 5. Add the entity to the {@link Scene}.
 *
 * ```javascript
 * // Create a mesh instance
 * const geometry = new pc.ConeGeometry();
 * const mesh = pc.Mesh.fromGeometry(app.graphicsDevice, geometry);
 * const material = new pc.StandardMaterial();
 * const meshInstance = new pc.MeshInstance(mesh, material);
 *
 * // Create an entity
 * const entity = new pc.Entity();
 * entity.addComponent('render', {
 *     meshInstances: [meshInstance]
 * });
 *
 * // Add the entity to the scene hierarchy
 * app.scene.root.addChild(entity);
 * ```

     * By default, the constructor creates a cone standing vertically centered on the XZ-plane with
     * a base radius of 0.5, a height of 1.0, 5 height segments and 18 cap segments. The cone is
     * created with UVs in the range of 0 to 1.
     *
     * @param {object} [opts] - Options object.
     * @param {number} [opts.baseRadius] - The base radius of the cone. Defaults to 0.5.
     * @param {number} [opts.peakRadius] - The peak radius of the cone. Defaults to 0.
     * @param {number} [opts.height] - The length of the body of the cone. Defaults to 1.
     * @param {number} [opts.heightSegments] - The number of divisions along the length of the cone.
     * Defaults to 5.
     * @param {number} [opts.capSegments] - The number of divisions around the tubular body of the
     * cone. Defaults to 18.
     * @param {boolean} [opts.calculateTangents] - Generate tangent information. Defaults to false.
     * @example
     * const geometry = new pc.ConeGeometry({

     *     height: 2,
     *     heightSegments: 2,
