This method can be used only with an
SCNRenderer object created with the
SCNRenderer initializer. Call this method to tell SceneKit to draw the renderer’s scene into the OpenGL context you created the renderer with.
When you call this method, SceneKit updates its hierarchy of presentation nodes based on the current system time, and then draws the scene.
