Included in the shareware edition of ZPlot3.1 are examples of all the built-in functions through a9, as listed below. The two-dimentional plots appear in reduced format (100X80) to save disk space. The three-dimensional projections are drawn at 640X480 resolution, 256 colors.
To expand the two-dimensional functions to a full-screen bitmap, select the New Function option on the Project menu and move the Size slider to the right. Click on Okay and the function will be redrawn to full size. This takes awhile for some functions, especially the hypercomplex ones(more math to do etc.) Don't expect Fractint speed, as ZPlot works only on a line by line basis(no solid guessing.) I've compared ZPlot to Fractint in its single-pass mode, and ZPlot was faster than Fractint.
To increased the resolution of the 3-D pictures, you will have to redraw them completely. Use Ctrl-C to clear the screen, then go to the New Function window and move the size slider. You may also have to adjust the Y-Offset slightly. All of the 3-D functions have more than one figure to redraw. One for the 3-D projection and one for the 3-D background. Some have another figure for a spherical projection as well(a moon.)
