Function Documentation

void* GetCurrentFont (    )

Return a pointer to the current font to be used in calls to Text() and Text3D().

int GetFontHeight (  int   fontid )

Get the height in pixels of the current font. See also: GetCurrentFont, GetFontHeight(), GetFontHeight(void*)

int GetFontHeight (    )

Get the height in pixels of the current font. See also: GetCurrentFont, GetFontHeight(void*)

int GetFontHeight (  void *   font )

Get the height in pixels for a specified font. Needed for calculating the Yoffset to go to the next line. See also: GetFontHeight(), GetFontHeight(int)

void SetCurrentFont (  int   fontid )

Set the current font. Use a number between 0 and 6, inclusive. See also: SetCurrentFont(void*)

void SetCurrentFont (  void *   font )

Set the current font. Use one of the GLUT font names: Possible values include: GLUT_BITMAP_8_BY_13 GLUT_BITMAP_9_BY_15 GLUT_BITMAP_TIMES_ROMAN_10 GLUT_BITMAP_TIMES_ROMAN_24 GLUT_BITMAP_HELVETICA_10 GLUT_BITMAP_HELVETICA_12 GLUT_BITMAP_HELVETICA_18 See also: SetCurrentFont(int)

void Text (  int   x, int   y, char *   format, ...   )

Draw text at the specified 2D location in screen coordinates in the current font. The text will be drawn in the current OpenGL color. The function accepts printf style format specification. See also: SetFont, Text3D

void Text3D (  float   x, float   y, float   z, char *   format, ...   )

Draw text at the specified 3D raster location. The text will be drawn in the current OpenGL color. The function accepts printf style format specification. See also: SetFont, Text
