	Method of using view frustrum culling for scaleable collision detection - US Patent 6734853 (Site not responding. Last check: 2007-10-29)
		An embodiment of the present invention is a method of using a view frustrum to cull models from a scene to reduce the number of object to object interactions that must be tested during collision detection processing.
		The view frustrum volume defines the parts of the scene that should be visible and thus rendered (in perspective for a pyramidal frustrum), when the position of a virtual camera is at the apex of the pyramid.
		View frustrum culling may be applied hierarchically with an in-order traversal from the root of the scene graph.

		The method of claim 1 wherein the respective axis line of each gas jet is positioned with respect to the inclined exterior surface of the nozzle frustrum such that substantially laminar as opposed to turbulent gas flow exits at said exterior surface.
		Measurement of pure gas pressure at the melt tube orifice while these frustrum angles were in use indicating that both produced backstreaming pressures in excess of 1 atmosphere, and that, therefore, improper operation was to be expected.

	Prefabricated concrete footings - Patent 6141936
		The frustrum footings and its composite mix design can be reinforced and sized to vary with demands of flexural, tensile and rigidity strengths as well as the punch shear executed by the posts.
		The precasting of the frustrum footings provides the advantage of being mixed at a plant, providing the quantative and qualitative advantage of consistent conditions each time the formula is mixed.
		The frustrum footings are preferably designed with a conical configuration in order to restrict the concrete used to the primary load bearing regions of the footing configuration.

		This methods build the viewing frustrum planes from the matrix resulting of the combination of view and projection matrix.
		Typically this method is used in camera code to update the viewing frustrum after the camera has changed position.

	[ODE] visibility detemination? (Site not responding. Last check: 2007-10-29)
		I very much doubt that you want to use collision at all for visiblity testing - it's bound to be much slower than a frustrum vs (ideally hierarchical) primitive test.
		So in that case special handling will still be required for collisions with the frustrum geometry.
		You could even consider using a large sphere geometry that fits exactly around your intended frustrum, since it's meant only for fast culling of definitively non-visible objects, and sphere geometries are very effecient to check collisions against.

		This does affect how the application is linked against Parasolid in order to obtain a correct runtime match between the application's Frustrum and the Parasolid stubs, ie, for the parasolid_test.c program, the behaviour of the example frustrum.lib and fg.lib.
		We choose to always register all our example routines: when linking against the archive library cc parasolid_test.c frustrum.lib fg.lib parasolid.lib or cc parasolid_test.c frustrum.o fg.o parasolid.lib then our routines are preloaded into the image and the stubs in parasolid.lib are never required - the registry does occur but nothing in Parasolid then uses the registration.
		When linking against a standalone image cc parasolid_test.c frustrum.lib fg.lib parasolid.so or cc parasolid_test.c frustrum.o fg.o parasolid.so then both the example routines and the Parasolid stubs are loaded, the stubs being hidden in the image and performing immediate transfer to the active code from the example libraries.

	Rom's Rants: "Amped 2" Tree Optimizations
		Now normally, visibility and collision detection on a surface that is essentially 2D can be easily handled through use of a quadtree.
		If it is, you continue to traverse the quadtree until you find an AABB that is not in the frustrum.
		Level of detail is not as easy, however, due to you having to check distance to each object in all visible frustrum nodes.

		Frustrum are thus far in their development not too reliant on the techy edge to their music, and though there may be odd time signatures involved and harmonic squeals being wrested from complaining guitars, the circumference of self-indulgent territory has yet to be crossed.
		Throne of Nails, by this stage in their careers, are rapidly becoming consummate professionals, and managed to persuade their equipment to do a much better job than the opening act's.
		Some new material was, I think, thrown in, although I'm actually not 100% certain, but it hardly mattered because the venue was simply pummelled and pummelled and pummelled some more under a merciless avalanche of precise, yet not bland, battery.

	Which data structure is right for the job? [Archive] - Beyond3D Forum
		There would be hints within each tile that would tell the frustrum culling algorithm whether to avoid certian tiles because there is a block floor, wall, ceiling or some other plane - basically the plane information would be stored and the culling algorthim would work with that.
		Since the frustrum culling algo would work near to far, the rendering would be roughly front to back.
		Hopefully an Octree allows you to find inside view frustrum nodes fast, which works for your fast locality change, however I don't see how you could handle slow locality change for terrain, and I'm not sure making the difference is usefull...

	TV3D :: View topic - Frustrum + Foggin = Frustration
		I'm using a mesh that acts like a skybox; in other words, its a large cube around the player that moves with the player and shows the sky in the distance.
		In theory, I thought I could set my frustrum very high, render my skybox, then set the frustrum down to reasonable level to only include the stuff I want the player's vision to include.
		If I keep the frustrum as a given amount, my fog shows up fine but setting the frustrum to always be at 10000 results in a massive drop in FPS and I don't want the players to be able to see the landscape that far away anyway.

		Workaround: Have something of a workaround for the earlier mentioned error where Havok won't create a rigid body from an object outside the camera frustrum (very very weird).
		The error actually goes away if you park another camera that can see the objects and render it to a small window.
		I'll need to fog up the second camera so it falls in with the background color and then remove it after the entire object is built.

		because its in space objects can be at vastly varying distances from the camera so the frustrum has to be huge to acomodate them all.
		The problem is that when the camera's distance to each of these objects changes the objects appear to fluctuate.
		but when i reduce the frustrum size from 60,000 units to a mere 400 units the anomaly is gone, but the problem is that only objects within a distance of 400 units are visible, my planets which are vastly farther away are now beyond the frustrum and hence invisible.
