Hi, great job with all the tutorials Swiftless. I’ve been reading through all the tutorials before this and wanted to suggest that you include pictures to show the differences
between different light settings and/or fog settings. I actually havent been using C/C++ to program with OpenGL, I’m using JOGL (Java bindings to OpenGL), and everything in your tutorials are helping me! Just that I have to set up a window and other similar things without using GLUT. Perhaps you can add further tutorials on some of the things in JOGL that differ from OpenGL. Two things off the top of head would include double-buffering and fullscreen antialiasing. But anyways, keep up the great work, and I’ll be looking through the rest of the tutorials!

This post explains what options OpenGL gives, but not what these options are, what fog model they represent.

Here is some more on how fog affects final color and what calculus is behind GL_EXP, GL_EXP2 and GL_LINEAR: http://www.opengl.org/resources/code/samples/advanced/advanced97/notes/node122.html

hi,

tutorial is very simple and easy, however I put the fog start and end lines with a limit between 2 and -2 , i was expecting some part of cube in the fog but it didnt change anything, i put these lines in the init() functoin just after glEnable(GL_FOG);
