WinXMorph

Introduction: WinXMorph is a free-for-educational-use program for Windows 2000, XP (see requirements) with which realistic still or animated crystal shapes (morphologies) are created from crystallographic data (metric, (hkl) - Miller indices and central distances) as input and *.wrl (VRML V2.0 utf8) files as output, that can be inserted on web pages.

JEMS — Java ems student edition

Introduction: Several parts of ems have been translated in the “java” language. Though java is slower than ‘C’, ‘C++’ or Fortran, its portability is better. In particular the graphical user interface (GUI) is almost independent of the target operating system. As a result jems has already been ported to Windows NT and Mac. Ports to Sun OS and Linux are under consideration. Despite the larger execution time, rather large calculation can be performed in less than a minute.

Lispix

Introduction: Lispix is a public domain image analysis program for Windows, written and maintained by David Bright. While including basic image processing functions found in NIH Image, ImageJ, Scion Image, ImageTool, and in some commercial programs, Lispix also has a collection of special purpose research tools for electron microscopy(1) and spectral imaging at NIST(2). In spite of that, many of the features incorporated into Lispix have been useful for other researchers. Lispix is useful for processing and analyzing images, and stacks of images or data cubes. Image pixels can be bit, integer, real, complex and color.

NIH Image, Scion Image, JImage

Introduction: NIH Image is a public domain image processing and analysis program for the Macintosh. It was developed at the Research Services Branch (RSB) of the National Institute of Mental Health (NIMH), part of the National Institutes of Health (NIH). A free PC version of Image, called Scion Image for Windows, is available from Scion Corporation. There is also Image/J, a Java program inspired by Image that “runs anywhere”. Image can acquire, display, edit, enhance, analyze and animate images. It reads and writes TIFF, PICT, PICS and MacPaint files, providing compatibility with many other applications, including programs for scanning, processing, editing, publishing and analyzing images. It supports many standard image processing functions, including contrast enhancement, density profiling, smoothing, sharpening, edge detection, median filtering, and spatial convolution with user defined kernels. Image can be used to measure area, mean, centroid, perimeter, etc. of user defined regions of interest. It also performs automated particle analysis and provides tools for measuring path lengths and angles. Spatial calibration is supported to provide real world area and length measurements. Density calibration can be done against radiation or optical density standards using user specified units. Results can be printed, exported to text files, or copied to the Clipboard.

SketchUp
Introduction: SketchUp is a simple but powerful tool for quickly and easily creating, viewing and modifying your 3D ideas. Click on a shape and push or pull it to create your desired 3D geometry. Experiment with color and texture directly on your model. Real-time shadow casting lets you see exactly where the sun falls as you model. Select from thousands of pre-drawn components to save time drawing.
