frustum

1. Geometry
a. the part of a solid, such as a cone or pyramid, contained between the base and a plane parallel to the base that intersects the solid
b. the part of such a solid contained between two parallel planes intersecting the solid

frustum

[′frəs·təm]
(mathematics)
The part of a solid between two cutting parallel planes.

viewing frustum

In 3D graphics, it is the area that is within the view of the user. When rendering images, graphics programmers must write routines that draw all visible objects within the viewing frustum and not waste processing time dealing with elements outside of it. See 3D graphics.

The Viewing Frustum The frustum is like a pyramid lying on its side with the tip clipped off. Everything between the near and far planes is the viewing area. (Image courtesy of Intergraph Computer Systems.)

Data modelers use frustum culling, the LOD approach, and other methods, to select rendering targets, and rendering is performed object-by-object even in simplified scenarios.
The slump test method is a simple way of estimating the yield stress of the soil since the yield stress is expressed as a function of water content, height of cylindrical frustum, slump height and material density (Mendez-Sanchez, 2012).
As shown in Figure 3, force quantity absorbed by the conical construction, which has endured the most degree, equals 11000N due to explosion in the distance of 10 meters from the ground surface; after that, hemispherical form absorbed quantity of 6800N; finally, frustum has the lowest absorbed energy from explosion with 5000N.
To remove this polarization-dependence, a two-dimensional (2D) periodic array of quadrangular frustum pyramids (QFPs) is proposed, and is illustrated in Figure 5(a).
