Add perspective projection, draw a sphere, and exercise GL lighting and shading.

- Use perspective projection with the camera placed at the center of the scene and capable of seeing the entire set of objects you have generated.

- Add a sphere to the library of objects. You CANNOT use the glutSolidCube/glutSolidSphere

-Add at least 4 light sources

-Use different types of light sources including:

1. point at a finite location,

2. point at infinite,

3. spot with different cut-offs and attenuation parameters

4. ambient light source

-Use different colors in the ambient, diffuse, and specular space for each light source

- At least one light source should be visible

Associate material properties with each object in the scene:

-Use different reflection coefficients in the ambient, diffuse, and specular space for each object.

-Define shininess

-Define normals and use flat as well as smooth, shading.

-Use the Gourad method to find the normals of common vertices on the cube.

- Take at least 4 snapshots of the scene with the light sources moving from one location to another between snapshots.

-Draw all the snapshots in one window using different view ports.

-Add shadowing (shadows that are due to the lighting) effects to the following objects from your scene: The cube, The sphere
