Question About Rendering

[kingnobro]

In the AnimationPak paper, there are two sentences:

1. every path control point is represented using barycentric coordinates withing one triangle;
2. We can then compute a deformed copy of the original element paths by “replaying” the barycentric coordinates computed in Sect. 3.

But I do not understand this operation, i.e., how to warp vector graphics to the new position based on the deformed mesh. Could you provide more information or give me some online tutorials? Thanks.
