Disadvantages of a mesh system

the disadvantages of a mesh based system is that the about of vertices in memory gets multiplied by the amount of frames ie 300 vertices in one frame and overall there are 1- frames there will be a total of 3000 vertices

this stacks up very quickly

The Advantages of skeletal animation

The advantages of skeletal animations system are that this system is very realistic it makes the model appear more lifelike and realistic and also you only have to animate the skeleton (which is about 50 bones a model) which saves alot of memory

i these pictures you can see a skeleton and a mes based character.in these pictures you can see the weigh curves the bigger the curve the bigger effect

the weight on a vertex is effect the bone has on the mesh, the bigger the curv is on the modle the bigger the effect it has on the mesh when you decrease the weight the skeleton the mesh dosnt deform properly hwne the skeleton moves and ends up looking like the picture in the right
