"ibrowse" lets the user view all the images in a directory as postage-stamp sized icons in a scrollable window. Moving the cursor over an icon displays information about that file. Double-clicking on an icon will display the image at full size. A simple pop-up menu allows navigating through different directories of the file system. After iconifying the images for the first time, ibrowse saves the icons and file information in two files, .ibrowse_dir and .ibrowse_icon, in each directory. The next time the directory is browsed, the icons are displayed very quickly. The action ibrowse takes when an icon is double-clicked can be easily customized, making ibrowse a very flexible tool. ibrowse is easily extensible to handle several different image formats. The executable "ibrowse" in this directory recognizes SGI (Haeberli) format .rgb and colorindex images. "ibrowse.il" also recognizes ImageLib format images, which includes the TIFF and FIT formats. The source for these executables, as well as more detailed documentation, is in the tar file "ibrowse.tar". The directory "lilhelper" contains the source code for the "Modeler's Little Helper" 3-D library and for three sample programs that use it, together with complete documentation. Modeler's Little Helper provides routines to build a variety of simple 3-D solid models in arbitrary format, including spatial coordinates, normal vectors, and texture coordinates.
