Sorry tabstop, I completed the question and made it better.

-----------------------------------------------------------

I have a class like such:

Code:

class Sphere
{
public:
Sphere(){};
~Sphere() {};
Sphere(string m_name) : name(m_name) {};
void SetValues(float m_posx, float m_posy, float m_posz,
float m_sclx, float m_scly, float m_sclz,
float m_r, float m_g, float m_b,
float m_Ka, float m_Kd, float m_Ks, float m_Kr,
float m_n)
{
Ka = m_Ka; Kd = m_Kd; Ks = m_Ks; Kr = m_Kr;
n = m_n;
radius = 1.00;
center.x = 0.00; center.y = 0.00; center.z = 0.00;
sphereColor.r = m_r;
sphereColor.g = m_g;
sphereColor.b = m_b;
SetTranformMatrix(m_posx, m_posy, m_posz,
m_sclx, m_scly, m_sclz);
};
//set the transfor matrix
void SetTranformMatrix( float posx, float posy, float posz,
float sclx, float scly, float sclz)
{
Trans[0][0] = sclx;
Trans[0][1] = 0;
Trans[0][2] = 0;
Trans[0][3] = posx;
Trans[1][0] = 0;
Trans[1][1] = scly;
Trans[1][2] = 0;
Trans[1][3] = posy;
Trans[2][0] = 0;
Trans[2][1] = 0;
Trans[2][2] = sclz;
Trans[2][3] = posz;
Trans[3][0] = 0;
Trans[3][1] = 0;
Trans[3][2] = 0;
Trans[3][3] = 1;
};
//should return the depth at which the the ray has intersected otherwise return -1;
double intersect(ray &m_ray)
{
double T_Inverse[4][4];
invert_matrix(Trans, T_Inverse);
//buncha lines here
}
std::string name;
double Trans[4][4]; //transition matrix
color sphereColor;
private:
point center;
double radius;
float Ka, Kd, Ks, Kr;
float n; //specular
};

and a function like such:

Code:

float compute_closest_intersection(ray &m_ray, Sphere * m_spheres)
{
float intersect = -1;
float temp_intersect;
for(int i=0; i < 3; i++)
{
temp_intersect = m_spheres[i].intersect(m_ray); //HERE HERE HERE HERE
intersect = (temp_intersect >= intersect) ? temp_intersect : intersect;
}
return intersect;
}

and in main I have

Code:

Sphere inputSphere[5];
float testiii = compute_closest_intersection(Thru_Pixel,InputSphere);

- and the problem: Trans[][] doesn't have values,

(where it was initialized in the SetTranformMatrix() function)

when the intersect is called from compute_closest_intersection function.

in a nutshell

Why doesn't Trans[][] keep the values assigned to it in the SetTranformMatrix() function.

-Thank you
