Sigh. Nodes and portals are a system whereby the 3D engine divides the world up into a series of "nodes", these are all cubic areas of 3D space with the same size. Using various visibility tests, the engine is able to determine which other nodes are visible from a given node, and which are not visible. Depending on which node the camera is in, DBP only has to draw objects in the nodes which it knows are visible from that one, rather than all the polygons which are inside the 6 clip planes (near, far, top, right, left,bottom).

Do you want Windows menus in your DBP apps? - Get my plugin: http://snow.prohosting.com/~clone99/downloads/tpc_menus_103.zip
