0 the part of a solid shape such as a cone that is between the base of the shape and a parallel plane through the shape or between two parallel planes through the shape
Reinforces made the gun look like "three frustums of cones joined together, so as the lesser base of the former is always greater than the greatest of the succeeding one."
The form of the stand is the frustum of a hexagonal pyramid reversed, about six or eight inches in diameter.
The plummet, shaped like the frustum of a cone, and weighing thirty pounds, was thrown out from the side in the line of the vessel's drift.
The ellipsoid volume was derived from length and diameter measurements at several points by approximating the cone ellipsoid as the sum of frustums.
Cone ellipsoid volume was approximated as a sum of frustums from length and diameter measurements at several points along the ellipsoid.
Some authors use "pyramid of vision" as a synonym for view frustum itself, i.e. consider it truncated.
View frustum culling is the process of removing objects that lie completely outside the viewing frustum from the rendering process.
In ray tracing, bounding volumes are used in ray-intersection tests, and in many rendering algorithms, they are used for viewing frustum tests.
