Update a mesh dynamically

Hello!

I want to make an object like a cloth.

For this issue i have to use the Mesh class. E.g. documentation of cocos creator has a good topic how to work with meshes. Mesh Resource · Cocos Creator

Cpp documentation has no descriptions how to work with it. 3D · GitBook

Does anybody have some examples about meshes of cocos2dx(c++)? Or maybe a link to any site where i can read about it.
