Create a custom FTGL glyph object. 
FIXME: maybe get rid of "base" and have advanceCallback etc. functions
- Parameters
- 
  
    | base | The base FTGLglyph* to subclass. |  | data | A pointer to private data that will be passed to callbacks. |  | renderCallback | A rendering callback function. |  | destroyCallback | A callback function to be called upon destruction. |  
 
- Returns
- An FTGLglyph* object. 
 
 
◆ ftglDestroyGlyph()
Destroy an FTGL glyph object. 
- Parameters
- 
  
    | glyph | An FTGLglyph* object. |  
 
 
 
◆ ftglGetGlyphAdvance()
      
        
          | float ftglGetGlyphAdvance | ( | FTGLglyph * | glyph | ) |  | 
      
 
Return the advance for a glyph. 
- Parameters
- 
  
    | glyph | An FTGLglyph* object. |  
 
- Returns

◆ ftglGetGlyphBBox()
      
        
          | void ftglGetGlyphBBox | ( | FTGLglyph * | glyph, | 
        
          |  |  | float | bounds[6] | 
        
          |  | ) |  |  | 
      
 
Return the bounding box for a glyph. 
- Parameters
- 
  
    | glyph | An FTGLglyph* object. |  | bounds | An array of 6 float values where the bounding box's lower left near and upper right far 3D coordinates will be stored. |  
 
 
 
◆ ftglGetGlyphError()
      
        
          | FT_Error ftglGetGlyphError | ( | FTGLglyph * | glyph | ) |  | 
      
 
Query a glyph for errors. 
- Parameters
- 
  
    | glyph | An FTGLglyph* object. |  
 
- Returns
- The current error code. 
 
 
◆ ftglRenderGlyph()
Render a glyph at the current pen position and compute the corresponding advance. 
- Parameters
- 
  
    | glyph | An FTGLglyph* object. |  | penx | The current pen's X position. |  | peny | The current pen's Y position. |  | renderMode | Render mode to display |  | advancex | A pointer to an FTGL_DOUBLE where to write the advance's X component. |  | advancey | A pointer to an FTGL_DOUBLE where to write the advance's Y component. |
