If you work in vfx field then you will appreciate this tool, VTrack is a vertices tracking scripted tool that allows you to track a selected vertex or an averaged vertices position of a deformed mesh (Alembic or point cached) and create a point helper with a backed animation of the tracked position.
You can use it later as a source for your effect ( blood burst, explosion... you name it) or you can turn on that point animation trajectory so you can visualize the animation path of that area in the mesh.
