Reuse animations with multiple models?

Is it possible to give multiple humanoid models the same animations without s开发者_开发百科tarting from scratch each time?

Yes. The process essentially boils down to first having a skeleton that multiple models are based off of. You then wrap the mesh around the skeleton and 'weight' each vertex by the bones in the skeleton that influence movement. You then apply the animation and transformations to the skeleton, not the vertices of the model, and the each of the vertices in the 'skin' move with the skeleton according to the weight given to each bone.

As Tre said, this is called 'Rigging'.
