First failure on IKFK switch.
The rig in the video below is that I created follow a tutorial about building a IKFK switch. Ironically, everything apart from the switch seems fine, it is jumpy when it comes to the switch point.
I am going to solve it, and use it for one of the L4 film "Time Machine". Here are some tips I concluded by doing the two different rigs:
1.For spine, the spline Ik tool is easy to control for basic movement, but need to be careful about the Hierarchy. FK is used for taking full control of it.
2.Head applies to mainly FK, the only place for IK on head is when the head move left to right like it is in the india dance.
3.Arms need both IK and FK controls, for creating unlimited movement more easily.
4.Legs is mainly IK with knees on FK. For example, Kicking.

General Basic Rigging
This is the short video of rigging text, which is with FK spine and IK arms and legs.

What is 3D Animation?
Basically, it is an outcome of the rapidly developing computer technology. 3D software allow people to create a simulated world in computer; in this world, people can build character and scene, put them together with a right scale; then according to the physics motion trajectory, using simulated tools to bring the characters into life; at last, put the textures on the characters and bring the light into the scene. Eventually, the sequence of images that computer generated is what we call 3D animation. Now it is mainly applying in PC/video games, commercials, feature films and etc.
It is a well-known fact that “Toy Story” is the first fully computer animated feature film of Pixar and the 3D animation history. Its dramatic appearance indicated that the era of CGI technique begins. The development of 3D Animation film can be seeing as three periods: First period is the end of last century when the Disney and Pixar first introduce this advanced technology to the world with Toy Story. However, in 2001, another Animation magnate “DreamWorks Animation SKG” has get back on his feet from the failure of the “Insect’s war” in 1998 (According to the data from boxofficemojo.com, the gross of “Antz” By DreamWorks SKG is much lower than “A Bug’s Life”). “Shrek” has become the second entirely computer animated series film, and this time, on the box office, “Shrek” has surmounted “Monsters, Inc.” by Pixar. From this point of time, 3D animation film industry moved into a period of rapidly developing. More and more audiences were affected by many 3D animation films, one of the most popular ones is “Ice Age”, another series 3D animation film by Blue Sky. The third period started in 2004, 3D animation film industry get in the golden age. 3D animation is no longer the exclusive product of Pixar, 3D animation films appear in everywhere of the world in different format with different contexts and narratives, people start wondering what is the limit of 3D animation. When “The Polar Express” first applied Motion Capture technique into 3D Animation film, which combines human acting and CGI, with the vivid and very realistic movement, “The Polar express” brought a huge impact to the industry. However, surprisingly the box office of “The Polar express” did not reach the expectation of the audiences. In the same year, another 3D animation film named “Appleseed” released in Japan, ended up with also unpleasant box office. Three years later, in 2007, “Beowulf” released with a huge amount of budget, however, its Domestic total gross is just over the half of the budget. At this point, the question is obvious: why the fully computer animated film is much more popular than the ones using Motion Capture technique? How to find the boundary between “so realistic” and “too realistic”?
To make sure the research covers all aspects in full-scale and more thoughtful, I set up a basic system which includes four parts: Physical and Facial, fast and slow. An ordinary character mainly has two kind of movement which are physical movement and facial expressions, and both of them can be fast or slow. I hope I can find out the boundary between the two kind of 3D animation which is fully computer animated and is using motion capture.
