It seems the btSoftbody use the PBD (position based dynamic) algorithm. But, it is different from the origina one (<a href="https://matthias-research.github.io/pages/publications/posBasedDyn.pdf" class="postlink">https://matthias-research.github.io/pag ... sedDyn.pdf</a>).<br><br>For example, the stiffness is used as:<br><br>l.m_c0 = (l.m_n[0]-&gt;m_im + l.m_n[1]-&gt;m_im) / m.m_kLST;<br><br>Is there any document to describe more details? Or where can I find a paper to decribe the used algorithm?<br><br>Any suggestion is appreciated~~~<p>Statistics: Posted by <a href="https://pybullet.org/Bullet/phpBB3/memberlist.php?mode=viewprofile&amp;u=14579">zhang_qiang</a> — Tue Apr 25, 2023 2:20 pm</p><hr />
