Reflectance Transformation Imaging
Polynomial texture mapping (PTM), also known as Reflectance Transformation Imaging (RTI), is a technique of imaging and interactively displaying objects under varying lighting conditions to reveal surface phenomena. The data acquisition method is Single Camera Multi Light (SCML). Origins The method was originally developed by Tom Malzbender of HP Labs in order to generate enhanced 3D computer graphics and it has since been adopted for cultural heritage applications. Methodology A series of images is captured in a darkened environment with the camera in a fixed position and the object lit from different angles (Single Camera Multi Light). Interactive software processes and combines the set of images to enable the user inspecting the object to control a virtual light source. The virtual light source may be manipulated to simulate light from different angles and of different intensity or wavelengths to illuminate the surface of artefacts and reveal details.

Texture Mapping
Texture mapping is a method for mapping a texture on a computer-generated graphic. Texture here can be high frequency detail, surface texture, or color. History The original technique was pioneered by Edwin Catmull in 1974. Texture mapping originally referred to diffuse mapping, a method that simply mapped pixels from a texture to a 3D surface ("wrapping" the image around the object). In recent decades, the advent of multi-pass rendering, multitexturing, mipmaps, and more complex mappings such as height mapping, bump mapping, normal mapping, displacement mapping, reflection mapping, specular mapping, occlusion mapping, and many other variations on the technique (controlled by a materials system) have made it possible to simulate near- photorealism in real time by vastly reducing the number of polygons and lighting calculations needed to construct a realistic and functional 3D scene. Texture maps A is an image applied (mapped) to the surface of a shape or poly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
3D Modeling
In 3D computer graphics, 3D modeling is the process of developing a mathematical coordinate-based representation of any surface of an object (inanimate or living) in three dimensions via specialized software by manipulating edges, vertices, and polygons in a simulated 3D space. Three-dimensional (3D) models represent a physical body using a collection of points in 3D space, connected by various geometric entities such as triangles, lines, curved surfaces, etc. Being a collection of data (points and other information), 3D models can be created manually, algorithmically ( procedural modeling), or by scanning. Their surfaces may be further defined with texture mapping. Outline The product is called a 3D model. Someone who works with 3D models may be referred to as a 3D artist or a 3D modeler. A 3D Model can also be displayed as a two-dimensional image through a process called 3D rendering or used in a computer simulation of physical phenomena. 3D Models may be created ...

Star Carr
Star Carr is a Mesolithic archaeological site in North Yorkshire, England. It is around five miles () south of Scarborough. It is generally regarded as the most important and informative Mesolithic site in Great Britain. It is as important to the Mesolithic period as Stonehenge is to the Neolithic period or Scandinavian York is to understanding Viking Age Britain. The site was occupied during the early Mesolithic archaeological period, which coincided with the preboreal and boreal climatic periods. Though the ice age had ended and temperatures were close to modern averages, sea levels had not yet risen sufficiently to separate Britain from continental Europe. Highlights among the finds include Britain’s oldest structure, 21 red deer stag skull-caps that may have been headdresses and nearly 200 projectile, or harpoon, points made of red deer antler. These organic materials were preserved due to having been buried in waterlogged peat. Normally all that remains on Mesolithic ...

Ashmolean Museum
The Ashmolean Museum of Art and Archaeology () on Beaumont Street, Oxford, England, is Britain's first public museum. Its first building was erected in 1678–1683 to house the cabinet of curiosities that Elias Ashmole gave to the University of Oxford in 1677. It is also the world's second university museum, after the establishment of the Kunstmuseum Basel in 1661 by the University of Basel. The present building was built between 1841 and 1845. The museum reopened in 2009 after a major redevelopment, and in November 2011, new galleries focusing on Egypt and Nubia were unveiled. In May 2016, the museum also opened redisplayed galleries of 19th-century art. History Broad Street The museum opened on 24 May 1683, with naturalist Robert Plot as the first keeper. The building on Broad Street (later known as the Old Ashmolean) is sometimes attributed to Sir Christopher Wren or Thomas Wood. Elias Ashmole had acquired the collection from the gardeners, travellers, and collecto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parian Chronicle
The Parian Chronicle or Parian Marble ( la, Marmor Parium, Mar. Par.) is a Greek chronology, covering the years from 1582 BC to 299 BC, inscribed on a stele. Found on the island of Paros in two sections, and sold in Smyrna in the early 17th century to an agent for Thomas Howard, Earl of Arundel, this inscription was deciphered by John Selden and published among the Arundel Marbles, ''Marmora Arundelliana'' (London 1628–9) nos. 1–14, 59–119. The first of the sections published by Selden has subsequently disappeared. A further third fragment of this inscription, comprising the base of the stele and containing the end of the text, was found on Paros in 1897. It has entries from 336/35 to 299/98 BC. The two known upper fragments, brought to London in 1627 and presented to Oxford University in 1667, include entries for the years 1582/81–355/54 BC. The surviving upper chronicle fragment currently resides in the Ashmolean Museum at Oxford. It combines dates for events ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kingston Lacy
Kingston Lacy is a country house and estate near Wimborne Minster, Dorset, England. It was for many years the family seat of the Bankes family who lived nearby at Corfe Castle until its destruction in the English Civil War after its incumbent owners, Sir John Bankes and Dame Mary, had remained loyal to Charles I. The house was built between 1663 and 1665 by Ralph Bankes, son of Sir John Bankes, to a design by the architect Sir Roger Pratt. It is a rectangular building with two main storeys, attics and basement, modelled on Chevening in Kent. The gardens and parkland were laid down at the same time, including some of the specimen trees that remain today. Various additions and alterations were made to the house over the years and the estate remained in the ownership of the Bankes family from the 17th to the late 20th century. The house was designated as a Grade I listed building in 1958 and the park and gardens are included in the National Register of Historic Parks and Gard ...

Philae Obelisk
The Philae obelisk is one of a pair of twin obelisks erected at Philae in Upper Egypt in the second century BC. It was discovered by William John Bankes in 1815, who had it brought to Kingston Lacy in Dorset, England, where it still stands today. The Greek and Egyptian hieroglyphic inscriptions on the obelisk played a role in the decipherment of ancient Egyptian hieroglyphs. Description The obelisk was originally one of a pair that stood at the east pylon of the temple of Isis at Philae. The other obelisk of the pair was broken into pieces in antiquity. The surviving obelisk consists of a long shaft, topped by a pyramidion and a rectangular base. The bottom of the shaft is a modern restoration. Including the modern base, it stands roughly seven metres tall. There are two inscriptions: a hieroglyphic text on the shaft and a Greek text on the base. An additional painted Greek text on the base was observed in 1815, but has now been lost due to weathering. The inscriptions are publ ...

Vindolanda Tablets
The Vindolanda tablets were, at the time of their discovery, the oldest surviving handwritten documents in Britain (they have since been antedated by the Bloomberg tablets). They are a rich source of information about life on the northern frontier of Roman Britain. Written on fragments of thin, post-card sized wooden leaf-tablets with carbon-based ink, the tablets date to the 1st and 2nd centuries AD (roughly contemporary with Hadrian's Wall). Although similar records on papyrus were known from elsewhere in the Roman Empire, wooden tablets with ink text had not been recovered until 1973, when archaeologist Robin Birley, his attention being drawn by student excavator Keith Liddell, discovered some at the site of Vindolanda, a Roman fort in northern England. The documents record official military matters as well as personal messages to and from members of the garrison of Vindolanda, their families, and their slaves. Highlights of the tablets include an invitation to a birthda ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
