<hr><a name="_details"></a><h2>Detailed Description</h2>
A triangle mesh, also called a 'polygon soup'.
<p>
It is represented as an indexed triangle list. There are no restrictions on the triangle data.<p>
To avoid duplicating data when you have several instances of a particular mesh positioned differently, you do not use this class to represent a mesh object directly. Instead, you create an instance of this mesh via the <a class="el" href="classPxTriangleMeshGeometry.html" title="Triangle mesh geometry class.">PxTriangleMeshGeometry</a> and <a class="el" href="classPxShape.html" title="Abstract class for collision shapes.">PxShape</a> classes.<p>
<h3>Creation</h3>
<p>
To create an instance of this class call <a class="el" href="classPxPhysics.html#29dcbbe128cef11eaf4ce5696c216dfd" title="Creates a triangle mesh object.">PxPhysics::createTriangleMesh()</a>, and <a class="el" href="classPxTriangleMesh.html#168cc0000372c63857d128d04f1d32fa" title="Decrements the reference count of a triangle mesh and releases it if the new reference...">release()</a> to delete it. This is only possible once you have released all of its <a class="el" href="classPxShape.html" title="Abstract class for collision shapes.">PxShape</a> instances.<p>
