SHAPE,from SHAPE Software, creates and displays the external morphology of crystals. It can display any single crystal and most twins and intergrowths.
The user enters the crystal axes lengths and angles, the symbol for the crystal class, and one face of each form (symmetry equivalent set). The crystal can be rotated and scaled. A stereonet can be displayed with the crystal, or stereopairs can be drawn automatically. Screen display and hard copy of even complex, interpenetrating intergrowths may be made in final finished form, with no extraneous lines.
SHAPE is available for Windows, Linux, and Mac OS platforms. In Windows versions, symmetry-consistent striations may be drawn on any or all forms. Central distances, which determine face sizes, can be changed interactively with the mouse. Anaglyph (two-color stereopair) mode allows 3D viewing with standard red-green glasses. Faces can be labeled with indices or form letters.
The Windows version of SHAPE comes in two editions, Standard and Professional. The professional edition allows the representation of quasi-crystals and a program for generating Cartesian symmetry matrices. Quasi-crystals are crystal-like shapes with non-crystallographic symmetry such as icosahedral. Cartesian symmetry matrices for any point symmetry group - the matrices for pentagonal and icosahedral groups - are provided.
The Professional edition can also draw sections through any crystal, at any orientation and depth. Moreover, sections can be draw sequentially at given time intervals for modelling crystal growth in section. The growth rates of individual forms can be constant with time, or can follow a general exponential growth-rate equation. This can be used to model the growth of twins, epitaxial intergrowths and even intergrowths of non-related crystals.
The Mac OS edition is similar to the Windows standard edition but also includes routines to facilitate drawing of crystals of complex morphology.
Crystal Libraries
The main library (700+ crystals) and supplementary library (200+ crystals), are based on the historical sets of wooden models designed in the 19th century by P. Groth and marketed by F. Krantz. Both include a book with drawings of all crystals in standard orientation. Compiled by Ulrich Burchart.
