frustum

Research I did at the time suggested that one of the few options was for game developers to explicitly create multiple view frustums. Most game engines don't do this, since it's difficult and time consuming.

Each sheet measured 560 mm x 590 mm x 5 mm and contained vertical frustums formed during manufacture with 15mm deep and 15mm diameter, which acted as miniature reservoirs, giving potential volume of 1.5 1/sheet.

In order to quantify buttressing and associated stem volume, the height and diameters of conical basal buttresses and connected tree boles can be transformed into frustums for calculating volumes and the volumes can be converted to ratios for each tree.

However, the existing models, such as shooting and bouncing ray (SBR) [4], bidirectional path tracing (BDPT) [12], brick tracing (BT) [13], ray frustums (RF) [14], prior distance measure (PDM) [8], and space division (SD) [15] techniques, require higher prediction time due to complex algorithms used and limitations of the used techniques.

A typical cone meter consists of a differential producer fixed concentrically in the center of the pressure retaining pipe by which a differential pressure can be obtained across the interface of two cone frustums via an internal port-way system.

serial 1894L cabbages, carrots, waggon after waggon, bearing green turnips, built up in bastions of cabbages nodding to their pyramids and frustums fall, yet never falling, walls of baskets with such skill that enclosing masses of beans and peas, a rope was sufficient pyramids of snow-white turnips, to secure the whole swaying howdahs of mixed pro- load duce - creeping along behind aged night-horses, who seemed ever patiently wondering between their hollow coughs why they had always to work at that still hour when all other sentient creatures were privi- leged to rest (p.

One can form pyramids, frustums, and cavities with dimensions from less than 1 [mu]m up to a few millimeters.
