Discussion

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 specified timestamp, and then draws the scene.
