opendx (previously ibm info explorer, also called plainly dx) is definitely a general-purpose software package bundle for info visualization and evaluation. it employs a data-flow driven client-server execution design and allows for a graphical system editor that permits the user to produce a visualization by using a position and click interface. dx runs on 7 big unix platforms too as windows 95/nt and it is made to get complete benefit of multi-processor systems from ibm, sgi and sun.
dx is developed on an internal info model, which describes and presents uniform entry providers for just about any information brought into, created by, or exported in the software system. this data product supports various distinct classes of scientific info, which may be described by their shape (size and variety of dimensions), rank (e.g., scalar,
Office 2010 Home And Business Serial, vector, tensor), sort (float, integer,
Microsoft Office Enterprise 2007 Keygen, byte, etc. or real, complex, quaternion), where by the info are located in area (positions), how the areas are associated with each other (connections),
Office Standard 2007, aggregates or groups (e.g., hierarchies, sequence, composites, multizone grids, etc.). in addition, it supports people entities required for graphics and imaging operations inside the context of information explorer. usual and irregular, deformed or curvilinear, structured and unstructured data also as "missing" or invalid data are supported.
the details of the info product are hidden at the person level. as a result dx operations or modules are polymorphic and appear typeless. the dx import module, which reads info for use within data explorer directly utilizes data in netcdf at the same time as other formats (e.g., hdf, cdf). one or more variables may be selected too as step(s) of a time series. data in conventional netcdfs are directly imported. since the dx info model is more comprehensive than the netcdf info model, a methodology to extend netcdf via attribute conventions (e.g., for unstructured meshes, non-scalar information and hierarchies) for use with info explorer is available.
dx supports quite a few realization techniques for generating renderable geometry from information. these include color and opacity mapping (e.g., for surface and volume rendering), contours and isosurfaces, histograms, two-dimensional and three-dimensional plotting, surface deformation, and so on. for scalar info. for vector data, arrow plots, streamlines, streaklines, and so forth. are provided. realizations may be annotated with ribbons, tubes, axes, glyphs, text and display of info places, meshes and boundaries. information probing, picking, arbitrary surface and volume sampling, and arbitrary cutting/mapping planes are supported.
dx supports quite a few non-graphical functions such as point-wise mathematical expressions (e.g., arithmetic, transcendental, boolean, sort conversion,
Microsoft Office Professional 2007 Serial, and many others.), univariate statistics and image processing (e.g., transformation, filter, warp, edge detection, convolution, equalization,
Windows 7 32bit Key, blending, morphological operations, and so on.). field/vector operations such as divergence, gradient and curl, dot and cross products, etc. are provided. non-gridded or scattered information may be interpolated to an arbitrary grid or triangulated, depending on the evaluation requirements. the length, area or volume of various geometries may also be computed. tools for information manipulation such as removal of information points, subsetting by position, sub/supersampling, grid construction, mapping, interpolation, regridding, transposition, and many others. are available.
tools for doing cartographic projections and registration too as earth, room and environmental sciences examples are available at cornell university via info.tc.cornell.edu. also see the ncdx tool for making netcdf files opendx compliant.
