For this program, you will create multiple files to allow the program to sort a collection of points so that you can find out which points fall behind others, allowing them to be skipped. The points to be sorted will be read in from a file that the user will specify using command line arguments. The format of the file is described in detail below. The files you will create will include:
Point.h will include an include guard, a struct named Point, and the functional prototypes required to create, display, and destroy an individual Point. A Point is made up of three double values: x, y, and z. The functions that are necessary for this program are as follows:
- Point* createPoint(double x, double y, double z);
- void displayPoint(Point* p);
- void destroyPoint(Point* p);
Point.cpp will contain all of the code necessary to implement the functions that are prototyped in Point.h.
Points.h will include an include guard, a struct named Points, and the functional prototypes required to create, display, and destroy Points. Points is a struct made up of an array of individual Points (Point** array) as well as the size of the array. The functions that are necessary for this program are as follows:
- Points* createPoints(const char* filename);
- void displayPoints(Points* p);
- void destroyPoints(Points* p);
Points.cpp will contain all of the code necessary to implement the functions that are prototyped in Points.h.
RenderOrder.cpp should control all interaction with the user and call the functions in Points.cpp to return the desired results. In addition, RenderOrder will need to define two additional functions outlined below:
- void sortPointsByDistance(Points* P, Point refPoint);
sortPointsByDistance should accept the Points read in from the input file as well as the reference point provided by the user.
