This code is released to the public domain: do whatever you want with it. Documentation about how to construct formats is provided as comments in the main method. zipped download (12 kB) provides the classes embedded in the source for a program called FormatTest that allows you to test the formatting method. This is useful for constructing tables using a monospaced font (see the StatMech program on the Computer Programs page for an example of such a table), and is meant to reproduce the most useful functionality in FORTRAN formatting statements. For example, the sequence of values 123, "play nice", 32300 formatted with " a = b = $$$$ c = #.#e+# " yields "a = 0123.00 b = play c = 3.23 e+4 ", a string with exactly the same number of characters as the format string. I hope to be updating this soon.įormatter Module: This class allows you to format a list of numerical and/or string values so that the formatted values always occupy the same number of characters that are in the corresponding format. Note: While one can view the code for these classes in the Xojo IDE, they will no longer compile, because the way that 3D calls are handled in Xojo is now completely different (based on Open GL instead of Quesa). This set of classes is subject to the GNU GPL license. Also, note that you have to have the Quesa framework suitably installed for your platform to use the classes. html help file in the same folder as the source code before compiling. zipped download (204 kB) provides the classes embedded in the source for a program called PDTest that displays some of the capabilities of the class, the help file for that program, and detailed. These methods have been extensively tested on Mac OS X 10.4.10, but have not been tested for Windows or Linux in their current form (though previous forms worked on Windows). An earlier version of these classes was used in the 3DEField and 3DBField programs (see the Computer Programs page). The space can also be set to autoupdate at a specified rate, making it easy to create 3D animations.
spheres, boxes, arrows).The predefined space displays three dimensional spaces of arbitrary size and provides easy hooks for rotating and zooming the view, for displaying coordinate axes, and for autoscaling and autocentering to keep objects in view.
PD3DClasses: This set of classes allows you to create a predefined 3DSpace that you can fill with predefined objects (e.g. Be sure to provide information about what platform you are using and what operating system you are running. If you spot bugs, have questions (that the documentation cannot help you with), have suggestions for code modification, or want a waiver from the terms of the license, please contact me at. These classes are open-source, and can be freely copied, modified, and used, subject to the licensing restrictions specified below. This page provides Xojo source code for some of the code classes that I (and/or student helpers) have written to support the programs posted on the Computer Programs page.
