ne of the main interests here is to display data, including graphics, on the web. This requires writing scripts to interface code running on a server with the web. One of the issues that is important whenever there is a user interface is security. In addition to the links given elsewhere, such as in the science and education section, a number of links for various test codes and scripts are given below.
As a better alternative to Microsoft's Vector Markup Language used for graphics, Adobe's Scalable Vecotor Graphics can be used, as illustrated with the example on this link. In addition to built in animation, it has a number of other advantages, including being able to run in several type of browsers. However, a plugin is required, which can be downloaded from Adobe's website.
Another example is an RGB color cube, where a face is displayed showing the merging of several colors.
This is a test example written in PHP that can be used eventually for online quizzes. Such quizzes would obviously be longer and more detailed, and students would have to enter a password or some ID, as well as a possible time limit being imposed.
Steward Observatory's Mirror Lab is a world leader in making mirrors for large telescopes. The link takes you to a Flash animation I created of an objective consisting of seven 8.4 meters mirrors, six of which require off-axis figuring. A Flash player is required to view the animation.
This link shows some interactive test graphics performed in Java. Your browser may require a suitable plugin to be downloaded.
This link shows how to link Java, C and FORTRAN code together, and can be very useful if a graphical user interface in Java is required for existing C and/or FORTRAN codes.
