This has the advantage + * that output is easy and fast, and the disadvantage that you have to give a + * whole bunch of parameters which determine the direction of sight, the mode of + * colorization, the scaling of the height axis, etc. (Of course, all these + * parameters have reasonable default values, which you may want to change from + * time to time.) At present, this format only supports output for two-dimensional + * data, with values in the third direction taken from a data vector. + * + * Basically, output consists of the mesh and the cells in between them. You can + * draw either of these, or both, or none if you are really interested in an empty + * picture. If written, the mesh uses black lines. The cells in between the mesh + * are either not printed (this will result in a loss of hidden line removal, i.e. + * you can "see through" the cells to lines behind), printed in white (which does + * nothing apart from the hidden line removal), or colorized using one of the + * data vectors (which need not be the same as the one used for computing the + * height information) and a customizable color function. The default color + * functions chooses the color between black, blue, green, red and white, with + * growing values of the data field chosen for colorization. At present, cells + * are displayed with one color per cell only, which is taken from the value of + * the data field at the center of the cell; bilinear interpolation of the color + * on a cell is not used. + * + * By default, the viewpoint is chosen like the default viewpoint in GNUPLOT, i.e. + * with an angle of 60 degrees with respect to the positive z-axis and rotated + * 30 degrees in positive sense (as seen from above) away from the negative y-axis. + * Of course you can change these settings. + * + * EPS output is written without a border around the picture, i.e. the bounding box + * is close to the output on all four sides. Coordinates are written using at most + * five digits, to keep picture size at a reasonable size. + * + * All parameters along with their default values are listed in the documentation + * of the #EpsFlags# member class of this class. See there for more and detailed + * information. + * + * Please note that due to the various transformations each patch has to undergo + * before actual outut, memory requirements may be rather large for large numbers + * of patches. + * * * \subsection{GMV format} * -- 2.39.5
