void hersheyDrawLetterOpenGL (unsigned char ch, int drawendpoints)

This routine generates a sequence of OpenGL drawing commands that can be captured in a display list for fast subsequent rendering of each of the font glyphs. More...

void hersheyDrawInitLetter (hersheyhandle *hh, const char ch, float *lm, float *rm)

For VMD FileRenderer subclasses, it is most convenient to generate the font glyphs on the fly. This routine initializes a glyph rendering context for the requested character, to be accessed by subsequent calls to hersheyDrawNextLine(). The lm and rm values are X coordinate offsets to be applied before (lm) and after (rm) rendering the glyph, to produce the correct text spacing. More...

int hersheyDrawNextLine (hersheyhandle *hh, int *draw, float *x, float *y)

This routine computes the next glyph stroke vector, returning false for a run of connected strokes, and true when the stroke ends. It sets the value of the 'draw' parameter to true when X and Y are set, which allows the caller to determine when strokes begin and end, and to connect the segments with whatever geometry works best for the specific renderer.
