Lecture 18: Physical Simulation (19)

I'm confused how dividing by the original length changes anything from the previous model. How would this look different from the original model?

Confused on what is the problem that we actually solve here. I understand that we want the same stretch for 10x10 mesh and 20x20 mesh, but why do we want to consider the strain?

If we had the same spring constant for all edges in a mesh, then a finer mesh would have a lot more springs of the same strength packed into a smaller area, which would look different because a bunch of small springs attached to each other do not behave the same as a bigger spring with the same spring constant.

So to my understanding. The essence is to change the spring constant by normalizing the length to have the same cloth simulation?
