Like we have to recreate the shadow depending on the position of the lights, then we create a function that receive the lights atttributes so it can work in a appropiatte way dependending on the lights, and the normal vector that this create

We finally accomplished doing the shadows.

We have a problem, but it seems that we are close to fullfill the shadow animation. We have the flat images of the planets in the Floor. But they have textures, and we want only to have a black color, like the shadows.

We are looking the war to work with the shadow, it seems a little complicated because it seems to works with normal vectors, and we have to understand that.

Like specified in the Project, we are going to work with two types of lights: SpotLights and Normal Lights

If we see the picture , we have little spheres that represent the positions of the three lights in triangular arrangement.

We add Some Walls to aprecciate more the FOG, it seems that the fog affect only the objects, but no the space of the environment.

We were using GP_LINEAR, but we research that there are two other types of Fog: GP_EXP and GP_EXP2.

We used the GP_EXP, and change to a lesser density

We are having problem in Fog, the planets seems to be all intense Gray. Even if we change density, it desnt Change

By pressing the 'P' key, we are able to see how the Spheres change their Textures; and for the floor we first press 'f' to make visible the Floor, then we can alternate Textures of Marble and Chessboard by pressing the 'g' key
