Blending Aggregation and Selection: Adapting Parallel Coordinates for the Visualization of Large Datasets
Many of the traditional data visualization techniques, which proved to be supportive for exploratory analysis of datasets of moderate sizes, fail to fulfil their function when applied to large datasets. There are two approaches to coping with large amounts of data: data selection, when only a portion of data is displayed, and data aggregation, i.e. grouping data items and considering the groups...
متن کاملTransforming Geocentric Cartesian Coordinates to Geodetic Coordinates by a New Initial Value Calculation Paradigm
Transforming geocentric Cartesian coordinates (X, Y, Z) to geodetic curvilinear coordinates (φ, λ, h) on a biaxial ellipsoid is one of the problems used in satellite positioning, coordinates conversion between reference systems, astronomy and geodetic calculations. For this purpose, various methods including Closed-form, Vector method and Fixed-point method have been developed. In this paper, a...
متن کاملBarycentric coordinates computation in homogeneous coordinates
Homogeneous coordinates are often used in computer graphics and computer vision applications especially for the representation of geometric transformations. The homogeneous coordinates enable us to represent translation, rotation, scaling and projection operations in a unique way and handle them properly. Today’s graphics hardware based on GPU offers a very high computational power using pixel ...
متن کاملExplicitly computing geodetic coordinates from Cartesian coordinates
This paper presents a new form of quartic equation based on Lagrange’s extremum law and a Groebner basis under the constraint that the geodetic height is the shortest distance between a given point and the reference ellipsoid. A very explicit and concise formulae of the quartic equation by Ferrari’s line is found, which avoids the need of a good starting guess for iterative methods. A new expli...
متن کاملAdapting man adapting: curing, helping, consoling.
On the occasion of the one hundredth anniversary of Yale University School of Medicine, I was invited to deliver the Silliman Lectures that were published in 1965 under the title Man Adapting. The main theme of the lectures and of the book was that the states of health and disease are to a large extent the expressions of the success or failure of the adaptive responses made by the person to the...
