<hr><a name="_details"></a><h2>Detailed Description</h2>
Describe the contact point between two geoms.
<p>
If two bodies touch, or if a body touches a static feature in its environment, the contact is represented by one or more "contact points", described by <a class="el" href="structd_contact_geom.html" title="Describe the contact point between two geoms.">dContactGeom</a>.<p>
The convention is that if body 1 is moved along the normal vector by a distance depth (or equivalently if body 2 is moved the same distance in the opposite direction) then the contact depth will be reduced to zero. This means that the normal vector points "in" to body 1. <hr>The documentation for this struct was generated from the following file:<ul>
<li><a class="el" href="contact_8h-source.html">contact.h</a></ul>
