Project II: 3D Wire Modeling

Using Project I code you must:

• Transform a 3D point to a 2D point given the following information about the world:
  • The position and angles in the world you are viewing from.
  • The size of the window on the world.
  • Distance from behind and in front of the view plane to clip.
  • The window size on the screen.
• Draw a given point in a window
• Draw a given polygon in a window.
• Read a file consisting of 3 floating point values as values of the x,y,z coordinates of polygon points and plot the given polygon after asking me how far can I see(depth) and the position and orientation of where I want to look. It is text formatted as follows:
  • Integer : Number of points
  • For Number of times
  • Read Three Floating Point Numbers: These are one Point in 3D
  • Example:

4

0 0 0

0 5 0

5 5 0

5 0 0

You will be responsible for this project in groups of two people. You must comments all your code effectively so that I can follow what you are doing in them. You may write the code in XWindows or MSWindows 95/NT.

Here is the main class to implement:

class Graphics3D{

public:

Graphics3D(Point3D &VRP, Point3D &angles,

double front, double back,
double umin, double vmin, double umax, double vmax,
double xmin, double ymin, double xmax, double ymax);

~Graphics3D();
Vector * Transform(Point3D &pt);
Vector * Normalize(Vector &pt);
Point3D * Map(Vector &pt);

private:

//add your data structures

};
