hi, i'm writing a program that reads in 3d coordinates for a vertex and the edges that connect them, then projects the 3d image. right now i'm working with the implementation of the wireframe class, relevant prototypes (i've left some out) here:

class wireframe{
private:
    vertex *points;	    // an array of points that define the object
    vertex *ppoints;	    // the projection of the points that define the object
    int npts;		    // number of points
public:
    wireframe();           // constructor
    void readin(char* filename);   
    void project();        

};

vertices are defined with x, y, and z float coordinates. my readin function works fine, but once i get to the project function in the main program, the value for npts and the values within the array points[npts] are all set back to 0 even though i've set them while reading them in from the file. could someone explain why this is happening and what i can do to ensure that the values read in from the file carry over to the next part of the program?
