IEngine

    • The IEngine interface supports multiple implementations of the Filament engine, including FilamentEngineWrapper and HeadlessEngineWrapper.

    • It provides methods for creating and destroying core rendering components like cameras, scenes, renderers, and swap chains.

    • Developers can use IEngine to manage resources such as materials, textures, vertex buffers, and index buffers.

    • IEngine offers access to Filament's LightManager, RenderableManager, and TransformManager for manipulating scene elements.

    • The interface includes methods for ensuring engine validity and synchronizing operations with flushAndWait .
