Some More GLUT tricks

• Text on the screen
• Glut supports two different types of text
  • Bitmaps
    • Yuck.
    • Don't scale, rotate, ...
    • Look pretty but just at one place.
    • There is a small range of fonts.
  • Stroke Fonts
    • Vector graphics
    • The clear choice of the good graphics person.
    • But there is a limited range of fonts.
• Look at stroke
  • glutStrokeCharacter(void * font, int character)
    • Two choices of fonts: GLUT_STROKE_ROMAN, GLUT_STROKE_MONO_ROMAN
    • This draws a single character on the screen.
    • And makes a call to glTranslatef to advance by character width.
    • This changes the translation matrix.
      • This is probably bad behavior, but it is what it is.
  • int glutStrokeWidth(GLUTstrokeFont font, int character)
    • Returns the width of the character.
  • GLfloat glutStrokeHeight (void * fontID)
    • Returns the heightof the font
• glLineWidth(GLfloat width)
