a.  Does a blendshape require the base mesh and the target mesh to have the same number of vertices? Explain your answer, with reference to how blendshapes actually work.

The blendshape are  using the base mesh and the target mesh to have the same number of vertices.  The blendshape may use the Paint Selection Tool to select the points. Then, creating the deformers – cluster.  Therefore, I can move my selected parts. Sometimes, the blendshape are not a smooth part, so I need edit the cluster weights. Changing some values and make the face more smooth.

b. Can blendshapes only be used for facial animation? If not, prove it! Animate something and post it on your  blog.

Blendshapes is not just use on the facial animation. 

c.  If you want a character to look angry, you might decide to create a target mesh of the character's head and then modify it to have an angry expression. This is NOT how it should be done. Why not? And what would be a better approach? (Hint: you want to give the animator as much freedom as possible.).

All the facial parts should be independent. The face should be like a real person.

Reflection

This is the first week of this term. During this week, I learn more about the facial expressions. How to use the facial tools to complete one word and the whole complete sentence. In fact, the first exercise is not do hard. I just animate the facial parts to do the works.

The  blendshape is quite fun for me. When I use the blendshape tool to move, the face will be move.
