His purpose is similiar to <a class="el" href="a03289.html">CQuadTree</a>, but it is a simple grid, so test are in O(1), not in O(log n). It is perfect for local lookup (like in collisions). Use it if you want to select small area, not large. Also, for best use, elements should have approximatively the same size, and this size should be little smaller than the size of a grid element...<p> +By default, the quad grid is aligned on XY. (unlike the quadtree!!!)<p> +Unlike the quadtree, the quadgrid is NOT geographicly delimited, ie, its limits "tiles"!! This is why no "center" is required. As a direct consequence, when you select something, you are REALLY not sure that what you select is not a mile away from your selection :) ....<p> +Also, for memory optimisation, no bbox is stored in the quadgrid. Hence no particular selection is made on the Z components...<p> +For maximum allocation speed Efficiency, it uses a CBlockMemory<CNode> to allocate elements at <a class="el" href="a03273.html#NL3D_1_1CQuadGridz774_2">insert()</a>. DefaultBlockSize is 16, but you can change it at construction.<p> +because elements may lies in multiples squares, QuadGrid use lists per square which points on elements. For faster allocation, it uses a CSTLBlockList<>. The entire quadGrid has its own CBlockMemory for the CSTLBlockLists. memoryBlockSize is the same than the blockSize for allocation of nodes.<p> +<dl compact><dt><b>Author:</b></dt><dd>Lionel
