This is a fairly standard tutorial showing how to create a smooth-shaded triangle.

Each vertex has its own colour, and the triangles colour gets shaded/ interpolated between adjacent vertices.

 To create this sphere I used the trusty old Quadric object again. but this time I also generated Normals for the sphere.

Next I set the material of the sphere (Specular Highlighting and Shininess)

And set the light position and enabled it.

 This is a modification on the previous tutorial.

In this OpenGL Tutorial I added coloured Ambient, Diffuse and Specular light.

Everything else stays exactly the same

 Here we are drawing a Torus (Doughnut) with one Blue light enabled.

It uses similar materials as the sphere we drew int the previous example.

Because we are not using the aux or glut libraries I added a function to create a torus in a Display List.

The function is called CreateTorus (As if you wouldn't have guessed).

 I was getting bored with all the tutorials so I decided to modify example 6.1d and add another light source with different light properties.

This was the end result.

 In this tutorial we rotate a light ( Shown as a cube) around a stationary torus.

I have rotated the scene 45 degrees to show a better angle for the lighting.

You can use your left mouse button to rotate the light

 This tutorial was developed to show different material properties, and how to use them efficiently.

You will notice that you do not have to call glMaterialfv every time you draw an object.

This call holds its state until another call to the same material property is made.

 In this tutorial you can use your mouse buttons to change the Diffuse Material properties of the sphere.

Use your left mouse button to change the red component.
Use your middle mouse button to change the green component.
And use your right mouse button to change the blue component.

 Here we use glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);  and 0.75 as the alpha value on all the colours

I have changed the colours because the original colour scheme, was hurting my eyes.

 This tutorial is slightly different from the one in the book, but shows the same principles.

 Here we show a spinning anti-aliased Icosahedron.

All the code for the anti-aliasing can be found in the glInit procedure.

I am having problems getting the correct behavior from example 7.5 (Anti-aliasing Filled Polygons) so I will post it later.

 This is an example of how to implement the three different types of fog.

In the original example they use Teapots, but because we dont use the aux or glut library ( wich generate these atomatically), I used Cubes.

Use you left mouse button to toggle between the three Fog Modes.
