Platform mound

A platform mound is any earthwork or mound intended to support a structure or activity.

Eastern North America

The indigenous peoples of North America built substructure mounds for well over a thousand years starting in the Archaic period and continuing through the Woodland period. Many different archaeological cultures (Poverty Point culture, Troyville culture, Coles Creek culture, Plaquemine culture and Mississippian culture) of North Americas Eastern Woodlands are specifically well known for using platform mounds as a central aspect of their overarching religious practices and beliefs. These platform mounds are usually four-sided truncated pyramids, steeply sided, with steps built of wooden logs ascending one side of the earthworks. When European first arrived in North America, the peoples of the Mississippian culture were still using and building platform mounds. Documented uses for Mississippian platform mounds include semi-public chief's house platforms, public temple platforms, mortuary platforms, charnel house platforms, earth lodge/town house platforms, residence platforms, square ground and rotunda platforms, and dance platforms.

Mound

A mound is an artificial heaped pile of earth, gravel, sand, rocks, or debris. The most common use is in reference to natural earthen formation such as hills and mountains, particularly if they appear artificial. The term may also be applied to any rounded area of topographically higher elevation on any surface. Artificial mounds have been created for a variety of reasons throughout history, including ceremonial (platform mound), burial (tumulus), and commemorative purposes (e.g. Kościuszko Mound).

Archaeology

North American archaeology

In the archaeology of the United States and Canada, the term "mound" has specific and technical connotations. In this sense, a mound is a deliberately constructed elevated earthen structure or earthwork, intended for a range of potential uses. In European and Asian archaeology, the word "tumulus" may be used as a synonym for an artificial hill, particularly if the hill is related to particular burial customs.

While the term "mound" may be applied to historic constructions, most mounds in the United States are pre-Columbian earthworks, built by Native American peoples. Native Americans built a variety of mounds, including flat-topped pyramids or cones known as platform mounds, rounded cones, and ridge or loaf-shaped mounds. Some mounds took on unusual shapes, such as the outline of cosmologically significant animals. These are known as effigy mounds. Some mounds, such as a few in Wisconsin, have rock formations, or petroforms within them, on them, or near them.

San Francisco

San Francisco (/sæn frənˈsɪskoʊ/), officially the City and County of San Francisco, is the cultural, commercial, and financial center of Northern California and the only consolidated city-county in California. San Francisco encompasses a land area of about 46.9 square miles (121 km²) on the northern end of the San Francisco Peninsula, which makes it the smallest county in the state. It has a density of about 18,187 people per square mile (7,022 people per km²), making it the most densely settled large city (population greater than 200,000) in the state of California and the second-most densely populated major city in the United States after New York City. San Francisco is the fourth-most populous city in California, after Los Angeles, San Diego and San Jose, and the 13th-most populous city in the United States—with a Census-estimated 2014 population of 852,469. The city and its surrounding areas are known as the San Francisco Bay Area, and are a part of the larger OMB designated San Jose-San Francisco-Oakland combined statistical area, the fifth most populous in the nation with an estimated population of 8.6 million.

Computer graphics

Computer graphics are pictures and movies created using computers - usually referring to image data created by a computer specifically with help from specialized graphical hardware and software. It is a vast and recent area in computer science.The phrase was coined by computer graphics researchers Verne Hudson and William Fetter of Boeing in 1960. Another name for the field is computer-generated imagery, or simply CGI.

Important topics in computer graphics include user interface design, sprite graphics, vector graphics, 3D modeling, shaders, GPU design, and computer vision, among others. The overall methodology depends heavily on the underlying sciences of geometry, optics, and physics. Computer graphics is responsible for displaying art and image data effectively and beautifully to the user, and processing image data received from the physical world. The interaction and understanding of computers and interpretation of data has been made easier because of computer graphics. Computer graphic development has had a significant impact on many types of media and has revolutionized animation, movies, advertising, video games, and graphic design generally.
