<hr><a name="_details"></a><h2>Detailed Description</h2>
This interface reprents a mesh of triangles.
<p>
It is useful to communicate geometry information outside of the engine. One place where this will be useful is for communicating geometry information to the collision detection plugin.<br>
All Crystal Space mesh objects (things, sprites, ...) should implement and/or embed an implementation of this interface.<p>
A triangle mesh has the concept of a vertex buffer and an array of triangles.<p>
Main creators of instances implementing this interface:<ul>
<li>Almost all mesh objects have several implementations of this interface.</li></ul>
<p>
Main ways to get pointers to this interface:<ul>
<li><a class="el" href="structiObjectModel.html#c894706a83d6c33d9a204e0638c63f1c" title="Get a triangle mesh representing the geometry of the object.">iObjectModel::GetTriangleData()</a></li></ul>
<p>
Main users of this interface:<ul>
<li>Collision detection plugins (<a class="el" href="structiCollideSystem.html" title="This is the Collide plug-in.">iCollideSystem</a>)</li><li>Visibility culler plugins (<a class="el" href="structiVisibilityCuller.html" title="This interface represents a visibility culling system.">iVisibilityCuller</a>)</li><li>Shadow stencil plugin </li></ul>
