---------- This is an announcement of our first public release of a 2D lattice simulation and diffraction calculation computer program. This software is designed for modeling of 2D lattices (with and without defects) and calculation of diffraction patterns. The support of 17 2D plain space groups and 5 types of defects (vacancies, powder, texture, substitution and disorder) as been implemented. The image of a 2D lattice can be saved into a file in PostScript or PNG format. The image of a relatively large size can be used for the producing of photo slides for a laser projector. The diffraction pattern calculation algorithm uses such parameters as the width and the height of the screen, the distance to the screen, the wavelength and the contrast of the diffraction pattern. This image, too, can be saved into a PostScript or PNG file. At the present moment, only black-and-white images can be produced. The parameters used for calculation can be saved into an XML file. Hardware and software requirements: - the processor of at least 500Mhz (or more, if you want to increase the speed of the generation process); - RAM of at least 512Mb (or more if you want to create very large images of the lattice); - The J2SE Java Runtime Environment installed (http://java.sun.com/j2se/1.4.2/) - Internet connection; The web site for the program is http://www.challenge-it.com/projects/2DD/ You can found projects for different types of crystallographic structures in the "Download -> Examples" section. Any comments and suggestions are welcome.
