4.3. PLOTTING

next, previous Section / Table of Contents / Index PC graphics screen output uses a video graphics array adapter (VGA, 640x480 pixels, 16 colors) while Unix/X.11 Windows graphics output depends on respective workstation color adapters (up to 1280 x 1024 pixels, 256 colors). Lattice sections generated by BALSAC/LATTICE are displayed either - layer-by-layer where plotting stops after each layer and waits for a key to be pressed or L-click before the next layer is displayed or - atom-by-atom where plotting stops only when interrupted manually or after the complete structure has been finished or - cell-by-cell stacking elementary cells where plotting stops only when interrupted manually or after the complete structure has been finished. Clusters generated by BALSAC/CLUSTER use only atom-by-atom display mode. After a plot is completed BALSAC shows an option menu line at the bottom of the screen or text/graphics window (Unix) listing all available fast plot options which reads for a BALSAC/LATTICE session Replot[udlrV][rRpPmM+] analyze[Q] stack[LS] trnsf[T] qmen[O] sho[EI] [?,]esc and for a BALSAC/CLUSTER session Replot[udlrV][rRpPmMC+] analyze[Q] stack[LS] trnsf[T] qmen[O] sho[EI][?,]esc This allows you to generate further plots/listings with changed graphics parameters, analyze the lattice section or cluster, or return to the respective main option menus. All options are described in detail in Secs. 6.2.9, 6.3.7. In mouse menu mode of the BALSAC Unix/X.11 version the above menu lines are replaced by respective text inside the menu window from where all options can be selected, see Sec. 3.3.8 The graphical display process may be interrupted by pressing [blank] or clicking the mouse inside the graphics window where after pressing [C] (or L-click) resumes plotting in continuous mode. [,] (or R-click) completes the wire frame outlining the lattice section or cluster (if selected) and BALSAC assumes the plot to be finished as indicated by the menu line showing at the bottom of the screen. This allows you to return to the main option menu (press [,], R-click) or to use any of the plot keys described above. [/] (or B-click) resumes plotting in single atom mode after which each atom is displayed only after pressing a key or L-click. If [/] is pressed (or B-click) in single atom mode plotting will be continued in continuous mode. In mouse menu mode (Unix/X.11 version only) interrupting the display process results in a menu window which includes the three options above and allows you to select by L-clicking the appropriate window area. In addition to interactive graphical output color and gray scale PostScript file output of a given structure plot is possible, see Secs. 6.2.8, 6.3.6. These files can be printed on PostScript laser printers to yield graphics prints of publishable quality exceeding the screen resolution by far. next, previous Section / Table of Contents / Index
