OpenGL

High Performance Graphics

Gabriel Rosa Jun/2001

Introduction
- what is fltk?
  1. lightweight widget set and windowing kit
  2. interested in:
    - openGL
    - Object Orientation
    - event handling
- what is opengl?
  1. high level graphics library
  2. well supported through drivers for hardware
  3. easy to use
  4. very powerful
  5. can be very frustrating
- why do we care?
  1. obj oriented opengl encapsulation is good, orderly
  2. fltk event handling is very nice
  3. fltk toolkit is more refined than glut/glui
  4. fltk is a toolkit, gl is a graphics library, hooks allow best of both worlds to work together
  5. because we want pretty gui applications (except Pete)
Topics Covered:
- fltk:
  1. window drawing
  2. event handling

  2. perspective vs. ortho
  3. modelview vs. projection vs 2d
  4. setting color
  5. displaying primitives in 2d and 3d
