To all the readers of this list. This evening I refreshed my homepages about Sundials. The most important change is that from this moment my software is free to all members of any Sundial Society. You can download it from my homepage http://www.iaehv.nl/users/ferdv/
The software consits of : ZONWVLAK.zip : the DOS based package used by several diallists all over the world. It was sold by the NASS, the BSS and by myself. If you are a new user you have to download this package first. ZWVLAK95.zip : a windows 95 interface which make the use of Zonwvlak much easier if you run windows 95. It is planned to make a better helpfile for Zonwvlak. A first version is made by Harold Brandmaier and will become available in the future. There is a link PRINTGL to a page where Printgl can be downloaded. With this program a drawing of a sundial can be printed to paper. If you want to know in what way all kind of lines on a flat sundial can be computed read the pages "Method to compute flat sundials". This method is used in my program Zonwvlak. Happy dialling to all. Fer de Vries, Netherlands.
