African People

African concept of visual design was derived from the concept of creation which has been noted to be the exclusive preserved of the gods. Design and art as it were, are created with intrinsic value such as inventions, innovations technical prowess and deep imagination. To create design in Africa content is unique therefore; design forms which keep on occurring in African arts obviously have significance in the life of those who created them for the purpose of aesthetics and beauty in African digital designs This paper is not mere description or just an historical narration of African digital design and visuals but centers on the deviation of African people from their original system of design and imbibing computer graphic digital application as an alternative to pen and paint box creative designs The paper concluded that the conventional African visual designs should be guided against because African design is center on values and experience which is concern with the essence of African personality and existence of transmission of design legacy from parents to children which leads to physical or merit pattern, which later becomes the object of perception, admiration, and utilization. Computer graphics and visual design reflection in African design is therefore cognitive reaction scientifically which implies conceptualization and, inspiration in 21st century.

The Creation

La aplicación de la Realidad Virtual (RV) en la creación artística se remonta a la década de 1990, cuando se comercializan losprimeros sistemas de RV. Sin embargo, los altos costos y lasdificultades técnicas para realizar y exhibir este tipo de obras limitaron la exploración artística de esta tecnología. En la segundadécada del s. XXI, la RV ha experimentado un renacimiento debido,en parte, a los avances tecnológicos en la computación gráfica y las interfaces físicas, bien como a su abaratamiento. Todos estos factores, están reimpulsado la utilización de la RV en las artes al facilitar la creación y exhibición de las obras. Virtual Reality (VR) art can be traced back to the 1990s, whenthe first VR systems were commercialized. However, the art exploration of this technology was limited due to the high costs and technical difficulties to create and exhibit VR artworks. In the second decade of the 21st century, VR has experienced a renaissance partly because of the technological advances in computer graphics and physical interfaces and the reduction of their cost. All these factors have revitalized the use of VR in the arts by facilitating the creation and exhibition of artworks.

The article is dedicated to Kiev ex-libris school role (EL) in modern Ukrainian printmaking. The loss process by a bookplate of utilitarian, applied functions and its transformation into an independent work of art, collectors' object of interest with an appreciated art value is described. The ex-libris schools formed in the first quarter of the 21st century are emphasized, the main trends of the bookplate development predominant centers are defined (Kiev, Lvov, Odessa, Luhansk). Printmaking techniques, typical for a particular ex-libris school, are marked. Kiev bookplate school, as one of the leading centers for the classical xylography traditions preservation, is underlined. The most significant masters, working in these techniques, are presented, the technological process evolution is indicated and its main reasons are emphasized. The problem of opposition between the old and new in the art of printmaking is touched upon by example of classical techniques and gathering momentum computer graphics (CGA) coexistence.

High Performance Computer

Stereo pairs of electron microscope images provide valuable visual impressions of the three-dimensional nature of specimens, including biological objects. Beyond this one seeks quantitatively accurate models and measurements of the three dimensional positions and sizes of structures in the specimen. In our laboratory, we have sought to combine high resolution video cameras with high performance computer graphics systems to improve both the ease of building 3D reconstructions and the accuracy of 3D measurements, by using multiple tilt images of the same specimen tilted over a wider range of angles than can be viewed stereoscopically. Ultimately we also wish to automate the reconstruction and measurement process, and have initiated work in that direction.Figure 1 is a stereo pair of 400 kV images from a 1 micrometer thick transverse section of frog skeletal muscle stained with the Golgi stain. This stain selectively increases the density of the transverse tubular network in these muscle cells, and it is this network that we reconstruct in this example.

EM specimens often contain 3-dimensional information that is lost during micrography on a single photographic film. Two images of one specimen at appropriate orientations give a stereo view, but complex structures composed of multiple objects of graded density that superimpose in each projection are often difficult to decipher in stereo. Several analytical methods for 3-D reconstruction from multiple images of a serially tilted specimen are available, but they are all time-consuming and computationally intense.
