how can i seam cloth piece use bullet

[yoogera]

hi, now i dev a cloth simulation system use bullet. i can create btsoftbody from triangle mesh, but this btsoftbody is just a cloth piece, is anyone know how to seam these pieces into a cloth.

now i do it by change bullet source code, i add a function to change the btsoftbody::btNode to its seam btsoftbody's btNode. this can do right but is there any other method to seam two btsoftbody node by node?

For adding seams, you should insert additional distance constraints (with a high stiffness) at the adjacent edges of the two cloth pieces. This will ensure that the two cloth pieces stick together.

thk you, i have done it in that way, but i found it's collision process may wrong. because this extra links must insert into a softbody(b), and one node(nodeA) of link is in another softbody(a). so if softbody(b) is simulation after softbody(a), the nodeA may pass through the rigid body between softbody(a) and softbody(b).
