CS 5610/6610 - Spring 2021 - Interactive Computer Graphics

Project 1 - Hello World

This first project is about setting up the environment for using OpenGL. We will create an OpenGL window and color it using basic OpenGL functions.

Requirements

• Use C/C++.
• Use GLUT, FreeGLUT, GLFW, or another UI library of your choosing to create an OpenGL window.
• The OpenGL viewport size must be explicitly specified.
• Set the background color of the window using OpenGL calls.
• The "Esc" key must close the window.
• All OpenGL-related headers must be placed under the GL directory of an include path and included using forward slash. If you use GLFW, it can be in its default header location.
  

  #include <GL/freeglut.h>
  #include <GLFW/glfw3.h>
  

Additional Requirements for CS 6610 Students

• Automatically animate the background color.

Notes

If you are using GLUT or FreeGLUT, pay attention to GLUT functions like the following:

• glutInit
• glutInitDisplayMode
• glutInitWindowSize
• glutCreateWindow
• glutMainLoop
• glutLeaveMainLoop
• glutPostRedisplay
• glutSwapBuffers
• glutDisplayFunc
• glutKeyboardFunc
• glutIdleFunc

Mac OS X users can follow this tutorial for setting up FreeGLUT 2.8.0.
