hahaha, good cool, after a few weeks of effort, finally put the fabric calculation done.

Every night to see the curtains are depressed, why should have cloth this kind of thing, the traditional steel body physics theory can not handle the operation of the cloth.
Then began to study soft body physics, began to study the spring, began to study the semi-steel body, finally in this afternoon to solve the problem.

Although it was not so complicated to begin with, it was definitely a great achievement for those of me who have never touched the 3D and never touched the graphics.

The next step is to simulate the wind and to see if the movement of my cloth is still normal under the influence of the wind.
