High Quality Content by WIKIPEDIA articles! iClone is a 3D rendering and animation software program that enables users to make 3D animated films. It is notable for being one of the very few animation softwares (the other two being Muvizu and Autodesk MotionBuilder) that use a real-time "WYSIWYG" view to let animators see the results of their work immediately, and to play back animations in the viewport. This real-time feature is enabled by using a 3D videogame engine for instant on-screen rendering.
