void d3pltfnt (x, y, z, string, height, angle) D3AUX.C Level 3
 
float x, y, z The position in 3-D space in user units.
char *string The string to be plotted. The first character should be a font selection character/
float height The height of the string in inches (or cm).
int angle The angle of the string.
 
d3fntplt() plots a string on the output surface in 2-D space. The x, y, z location (given in user units) is converted to the projected x, y pixel location and the string is plotted flat, i.e., in the plane of the paper.
