<p>I haven't tried full collision detection (edge-edge, edge-face etc.), and don't plan on doing so soon, for reasons i mentioned here (<a target="_blank" href="http://www.grasshopper3d.com/xn/detail/2985220:Comment:147114">http://www.grasshopper3d.com/xn/detail/2985220:Comment:147114</a>)</p>
<p>I think just responding to vertices penetrating the volumes of other meshes/Breps should be enough for quite a lot of uses though.</p>

<p>No problem Daniel, it was only a test, I imagined something like that</p>
<p>but I have a curiosity, I would like to test the intersection beetwen a edges and face of the meshes to detect collision. Have you ever tried something like this?</p>

<p>Hi Paolo,</p>
<p> </p>
<p>At the moment collision is only for particles with static Breps.</p>
<p>I have implemented what I think should work for dynamic mesh/mesh collision, but it relies on a feature in the Rhino SDK that currently seems to have a bug which is stopping it from working.</p>

<p>you can find tutorials on the kangaroo user group pages.</p>
<p>You must have a brep that works as collision object, or you can set an uniform space (a sphere around a point) that works as collision space.</p>
