A lens is a custom view of the content in the repository. You can think of it as a fancy kind of list that will let you see content through the eyes of organizations and people you trust.

What is in a lens?

Drawing simple shapes with perspective

Module by: Bryson R. Payne, Ph.D.. E-mail the author

Summary: The first program in this OpenGL tutorial allows the user to view a blue 3D sphere on the screen.

:shapes1.jpg Discussion The first example in this set of tutorials is a program to draw a simple wireframe sphere. We will take this first step and go further in the tutorials that follow, but this serves as a simple test bed for us to try displaying any object or figure. Simply change the line that draws the glutWireSphere with the line(s) for your object to easily test your coding for errors.

Executable example: Click here for a running demo: simple.exe
