Exercise 3
1. 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.
Yup. with the same verticles, this allow the base mesh to work properly and accurately with the target mesh. Without the same number of verticles, the work will come out wrongly and will be corrupted.
2. Can blendshapes only be used for facial animation?
In my opinion, i think that this can also be used at controlling the size of a rig, the muscles of the rig too!
3. 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.)
The best is the the target mesh is on the eye brow, the eyes, the cheek, then mouth and the nose of the character. This could enable the animator to change to different types of expression other than the angry face.
