Article Abstract:
Viewpoint Digital has bundled Nichimen Graphics' Nendo volume-modeling software with its own LiveArt 3D rendering software to create a package for designing sophisticated custom-looking graphic elements for documents quickly and simply. Nendo is the 3D equivalent of a 2D drawing program, and as such it requires some time to learn. Its tutorials are effective, but becoming proficient with the program takes time. LiveArt comes with 300 3D models, although the review copy had only 50, including aircraft, furniture and flowers. The models are processed through one of 36 algorithms ranging from straight, illuminated 3D rendering to stylized watercolor, chalk and surreal effects. The results can be inserted into documents as standard images or as objects that can be edited with OLE technology. The bundle costs $99.95 for online download (50 models) and $129.95 for CD-ROM (300 models).

Article Abstract:
The MathWorks' $5,900 DSP Workshop CASE software includes version 3.0 of the DSP Blockset for Simulink that combines with Simulink to create a graphical tool for simulating signal processing systems using a 'software through pictures' methodology. The system models generated look like engineering schematics but are in fact fully functional system simulations. Software functions underneath the functional blocks operate on the specified input and generate output according to the appropriate algorithm. Simulink and the DSP Blockset are included in the DSP Workshop along with Matlab and the Signal Processing Toolbox. Among the spectral estimation algorithms provided are Burg, Covariance, Modified Covariance, Magnitude FFT, Short-Time FFT and Yule-Walker. The DSP Workshop is most useful to Matlab users, but others will find the package easy to learn and well documented.

Article Abstract:
Fortner Software's Noesys data management software makes it easy to access large amounts of technical, multidimensional data. The package adds many fine visualization tools to the Hierarchical Data Format (HDF), and a partnership with Research Systems Inc has led to the integration of the Interactive Data Language (IDL) into Noesys. Also added to the package are new map projections, subsetting features and import/export translators that facilitate conversion of data into HDF. Simple plots of complicated multidimensional data require only a few mouse clicks after the data has been converted to the appropriate format. More complicated operations require more knowledge of IDL. The freeware HDF browser may be the best tool for learning HDF, but it is not on the CD and has to be downloaded from the company's web site. Noesys costs from $495.
