katkaistu kartio A cone or pyramid whose tip has been truncated by a plane parallel to its base.

In a parabolic conoid this difference vaniſhes, the fruſtum being always equal to a cylinder of the ſame height upon the ſection of the conoid that biſects the altitude of the fruſtum and is parallel to its baſes.

This theorem holds good for complete solids as well as frustums, whether right or oblique(..).

However, when there are multiple view frustums (as in a tiled display wall), visibility culling time becomes substantial and cannot be hidden by pipelining it with other stages of rendering.

Here, the dynamics of the fluid-filled frusta of cones are considered (see Figure 5.5). The frusta are clamped at their roots and free at their ends.

In some women itthe os uteri is flat, in many more tuberose, and forming, as it were, a frustum of a sphere;(..).

Problem 22. Determine the volume of a frustum of a sphere of diameter 49.74 cm if the diameter(si) of the ends of the frustum are 24.0 and 40.0 cm, and the height of the frustum is 7.00 cm.
