Recently, our university network has become very unstable. I developed a windows version of the modeling web service. Please, visit http://facebook.com/lithopia for download and further updates. Thanks. JM After realized making things with 3D printers is a very attractive job, I wanted to contribute to this community as a programmer. I built this web service with my graduate students so that you can design and 3D-print high quality cylinder lithophanes in an easy way. We hope you enjoy this! http://maker.dongguk.edu/cylinder_lithophane/index.html Use web browser to open the web service at http://210.94.199.44/litho_client/index.html and drag-and-drop an image you want to carve on a cylinder. You may want to customize some parameters like cylinder radius, print thickness, etc.
