11. He gave the derivation of the volume of a frustum by a sort of infinite procedure. 12. He finds the volume of rectangular prisms, pyramids, and the frustum of a square pyramid. 13. Distributing contiguous 2D tiles of pixels allows for data scaling by culling data with the view frustum . 14. This allows us to use a paraboloid frustum where that form appears more appropriate than a cone. 15. The volume of each segment is calculated as the volume of a frustum of a cone where: 16. For the Ares I-X flight test, the frustum and forward skirt extension were made of aluminum. 17. The diameter of the frustum decreases from 20.7 metres at the base to six metres at the top. 18. Truncation of only the simpler vertices yields what looks like a tetrahedron with each face raised by a low triangular frustum . 19. Values outside of this range correspond to points which are not in the viewing frustum , and shouldn't be rendered. 20. It can be thought of as a spherical cap with the top truncated, and so it corresponds to a spherical frustum .
