WinTensor™ is a program for Windows with which representation surfaces are created from crystallographic data (metric, tensor components as input and several image files as output, including *.wrl that can be inserted on web pages and send to 3D-printers. 

(not to be confused with Damien Delvaux's Program of similar name recently released)

Below some example screenshots of the piezo-optic effect, the optical rotation, the elastic constants and second harmonics in quartz. Click on images to open pages showing how to insert interactive models on webpages.

About WinTensor™ and the author

Author of the program and this text is Werner Kaminsky. He has a research faculty position in the Department for Chemistry of the University of Washington, Seattle in Washington, USA. Born in Germany in 1959 going to school and after studying physics and then crystallography under Professor Siegfried Haussuehl, a PhD and a ‘Habilitation’ in  Cologne he moved first to Oxford to work at the Clarendon Laboratory in the Physical Crystallography Research Group of Professor Mike Glazer where he got a call to join Professor Bart Kahr in his research on dyed crystals and related phenomena. Half of the time is now spend in solving X-ray structures for the Department. The other half is dedicated to research and on rare occasions to projects like this: writing programs mainly for educational use. This is what Werner has to say about this program.

“This Program was started years ago in Cologne, Germany, winter 1999. Now I want to share my pleasure of writing and using WinTensor™ with members of educational institutions and friends of crystal in generals.

My reason of writing a program to generate representation surfaces and *.wrl files of tensors is simple: there are almost no such files on the internet (August.2004) and there is no program as such that calculates these shapes with build-in symmetry and tensor component tables.”
