Animation is the filming a sequence of drawings or positions of models to create an illusion of movement. It is an optical illusion of motion due to the phenomenon of persistence of vision.
High quality animations of SketchUp models can be made with IRender nXt . In IRender nXt animation is created by rendering scenes, moving the camera, and rendering the next frame. We pass the rendered scenes to QuickTime to create a .AVI movie. (Or as an option, you can create a .JPG image for each frame and assemble them into a movie later.)
