/**
 * @import { Entity } from '../../entity.js'
 */
/**
 * The RenderComponent enables an {@link Entity} to render 3D meshes. The {@link RenderComponent#type}
 * property can be set to one of several predefined shape types (such as `box`, `sphere`, `cone`
 * and so on). Alternatively, the component can be configured to manage an arbitrary array of
 * {@link MeshInstance} objects. These can either be created programmatically or loaded from an
 * {@link Asset}.
 *
 * You should never need to use the RenderComponent constructor directly. To add a RenderComponent
 * to an Entity, use {@link Entity#addComponent}:
 *
 * ```javascript
 * // Add a render component to an entity with the default options
 * const entity = new pc.Entity();
 * entity.addComponent("render");  // This defaults to a 1x1x1 box
 * ```
 *
 * To create an entity with a specific primitive shape:
 *
 * ```javascript
 * entity.addComponent("render", {
 *     type: "cone",
 *     castShadows: false,
 *     receiveShadows: false
 * });
 * ```
 *
 * Once the RenderComponent is added to the entity, you can set and get any of its properties:
 *
 * ```javascript
 * entity.render.type = 'capsule';  // Set the render component's type
 *
 * console.log(entity.render.type); // Get the render component's type and print it
 * ```
