Welcome
to the home of JCrystal, a computer program for creating,
editing, displaying and deploying crystal shapes.
JCrystal is a
PC Software (Win95 and above). We recommend to
use Microsoft Internet Explorer with the JCrystalApplet.
If you can see the animated logo on top of this
page your browser can be used with the applet.
JCrystal is a
stand-alone Java application. The included JCrystalApplet will run within web pages exported by
JCrystal. The Java runtime module and a Windows
installer is included with
the distribution. The installation program will automatically
create shortcuts on the desktop and the start menu.
JCrystal produces Vrml, Html, Gif and PostScript
output.
JCrystal allows you to export web pages, that will use
the included JCrystalApplet , so that you can deploy the generated shapes on the Internet for
viewing in Java-enabled
web browsers, such as Microsoft Internet Explorer or
Netscape.
On top of this page the JCrystalApplet
is running as a logo (removed, Applets not supported anymore).

"This program
allows a user to manipulate a crystal shape with mouse and
keyboard control with a realism almost equal to actually
holding a real crystal model." - David Barthelmy (webmineral.com)
"JCrystal's stereo
drawings are such a pleasure to view, rotate, even the
nice little Miller indices float in space. It's even
better than RasMol or Biosym (Materials Studio now)
software" - Prof. Manuel Laso (Spain)
"My mineralogy
students really love your program--it has helped make
crystallography more a matter of inquiry than
memorization." - Brooks McKinney (Hobart And
William Smith
Colleges)
"I am generally
very happy with your program. It is quite intuitive.
It takes the students not more that half
an hour to learn how to work with it and it certainly
enters a great element of fun in a matter
that sometimes is regarded as dull." - Prof. Peter
Van den haute (Belgium)
"I am attaching one
of my abstracts where I used your JCrystal software to
simulate crystal shapes. ... Your software was very useful
in this study." - D.C.Golden (NASA) (PDF1,
PDF2)
"It has been a
pleasure learning to use JCrystal." - Stephen Pierce
"The program is so
cool that I am having a hard time stopping myself from
playing around with it! What a great
tool for visualizing crystals!" - Brooks
McKinney

JCrystalApplet on
the Web |
Main Window. Here face no.15 is selected and its central distance
modified using the slider.
Shown is one of
the two form
selector tools. It lets you input a form {hkl} manually or by mouse click
on the Wulff net for
generating the list of equivalent planes (hkl).

Dave
Barthelmy kindly provided more than 4000 hkl-file templates and
about 668 complete shapes for
minerals from his database (htp://webmineral.com)
The templates contain the mineral name, lattice parameters and a
default set of face indices that have to be edited by the user
to obtain the actual crystal forms.

About 100 sample files were
provided by Udo Behner (www.kristallzuechtung.de)
