Summary
In this chapter, we moved from pure animation replays to animation blending.
We started with a brief overview of the three animation blending types that are part of this chapter. Then, we added simple blending between the binding pose and one animation clip, and worked on an example of cross-blending between two animation clips.
As the last step, we added the code for additive animation blending. Additive blending works differently compared to the other two blending types, and requires adding the ability to split the skeleton tree into two parts.
In the next chapter, we switch the topic entirely, and add new control element types to the UserInterface class. Some of the new elements will help us to clean up the user interface, while others will allow us to show more information about the internals of the renderer.
