<h1>NL3D::CMeshBlockManager Class Reference</h1><code>#include <<a class="el" href="a05998.html">mesh_block_manager.h</a>></code>
<p>
<hr><a name="_details"></a><h2>Detailed Description</h2>
A class used to render instances sorted by MeshGeom first, then per material, where possible. This allow optimisation because less renderState swapping are needed. WARNING: if you add MeshGeom to 2 different <a class="el" href="a02875.html">CMeshBlockManager</a> at same times, it won't work, and will certainly crashes (not checked/assert).<p>
NB VBHeap part works, even if no User interface use it. It don't give greate performance Add, but will may be used.<p>
