2.9 Graphics

Fasttalk has a range of commands to display output for 2D problems. These can also be used to display properties on surfaces for 3D problems. Commonly used commands include

contour gives a contour plot

arrow shows an arrow plot of a gradient field

shade gives a Gouraud shaded plot

prim displays the mesh

clear clears the graphics screen (black is equivalent)

tekk toggles the output between screen and PostScript output

These commands are also available through a point and click facility on the menu bar in the Graphical User Interface. For 3D graphics, Fastflo supports interfaces to pre- and post-processing packages from other vendors.
