14 * @brief Abstract base class for mesh rendering operations.

15 *

16 * MeshRenderer defines the interface for rendering mesh geometry using a specific

17 * graphics API. Implementations of this class are responsible for translating

18 * abstract render commands into API-specific draw calls.

19 *

20 * This class follows the Strategy pattern, allowing the rendering backend to be

21 * swapped without affecting higher-level rendering logic.

22 *

23 * Example usage:

24 * ```cpp

25 * // Typically used polymorphically through a concrete implementation

26 * std::unique_ptr<MeshRenderer> renderer = std::make_unique<OpenGLMeshRenderer>();

27 * renderer->render(command, frameUniforms);

28 * ```

29 *

30 * @see helios::ext::opengl::rendering::OpenGLMeshRenderer

43 *

44 * Implementations should apply the shader, bind the mesh geometry, set uniform values,

45 * and issue the appropriate draw call for the target graphics API.

46 *

47 * @param command The render command containing mesh, material, and per-object uniform data.

48 * @param frameUniformValues Frame-level uniform values (e.g., view/projection matrices).
