As an example, this tutorial uses a very simple file format called abc which is defined solely for this tutorial. Note, JavaView does not support this file format except in this tutorial. The abc format has a comment header, followed by a list of vertices in R3 and an optional list of faces. The loader generates a point set or an element set depending on whether faces are supplied. A sample geometry file is cube.abc. To write an own parser simply modify this loader. It is a good idea to name the loader by the extension of your file format. The applet parameter filename may be a relative name or the URL of an abc geometry file. View source code: PaLoader.java of applet, PgAbcLoader.java of loader, cube.abc, cubePoints.abc Here is an example of a cube in the sample file format abc. Note the faces are optional in this dataset.
