LIBPLOT3(3) BRL-CAD LIBPLOT3(3) NAME libplot3 - graphics interface subroutines SYNOPSIS void pl_3box(FILE *fp, int x0, int y0, int z0, int x1, int y1, int z1); void pl_3cont(FILE *fp, int x, int y, int z); void pl_3line(FILE *fp, int x0, int y0, int z0, int x1, int y1, int z1); void pl_3move(FILE *fp, int x, int y, int z); void pl_3point(FILE *fp, int x, int y, int z); void pl_3space(FILE *fp, int x0, int y0, int z0, int x1, int y1, int z1); void pl_arc(FILE *fp, int xc, int yc, int x0, int y0, int x1, int y1); void pl_box(FILE *fp, int x0, int y0, int x1, int y1); pl_circle(FILE *fp, int x, int y, int r); void pl_color(FILE *fp, int r, int g, int b); void pl_cont(FILE *fp, int x, int y); void pl_erase(FILE *fp); void pl_label(FILE *fp, const char *s); void pl_line(FILE *fp, int x0, int y0, int x1, int y1); void pl_linmod(FILE *fp, const char *s); void pl_move(FILE *fp, int x, int y); void pl_point(FILE *fp, int x, int y); void pl_space(FILE *fp, int x0, int y0, int x1, int y1); DESCRIPTION These subroutines generate graphic output commands for processing with the plot(1) plotting filters. They are slightly more general than those in libplot as these take a file pointer. They also include the BRL 3-D extensions to the plot intermediate code. Pl_space or pl_3space must be used before any of the graphic primitives to declare the amount of space necessary. See plot3(5). Pl_box or pl_3box draws a box between the two given opposite points. The ''pen'' will be left at the second point. Pl_circle draws a circle of radius r with center at the point (x, y). Note that circle and arc cannot be transformed in three space if one is using a filter to do that. Pl_arc draws an arc of a circle with center at the point (x, y) between the points (x0, y0) and (x1, y1). String arguments to pl_label and pl_linmod are terminated by nulls and do not contain new-lines. There are also 2-D and 3_D double-precision versions, with arguments identical to their counterparts above. The naming conventions are to change the prefix to "pd"; examples are thus pd_point and pd_3point. Vector versions for 3_D (also double-precision) are prefixed "pdv", as in pdv_3point. See plot3(5) and plot(5) for a description of the effect of the remaining functions. FILES /usr/brlcad/lib/libplot3.a produces output for plot(1G) filters WARNINGS In order to compile a program containing these functions in file.c it is necessary to use ``cc file.c -lplot3''. Color specification and three-dimensional primitives are BRL extensions to the "unix plot" language that are not generally found on other systems.
