CGI of human heads

[peter hurley]

I am looking at producing CGI displays of human heads via C++ and OpenGL
I have just started to learn C++ and would like to ask for any guidance that could be given.


//Using laser line triangulation scanning of the human head to obtain
//surface co-ordinates computing through CGI for 3D display (OpenGL)
//Step 1 a program for reading xyz co-ordinate values into an array
//and then further dividing into three coloum array's
//Code::Blocks 8.02 in C++ GNC GCC Compiler

[code]
#include <iostream>
using namespace std;

int main()
{

float ax[5];
float ay[5];
float az[5];

float array[5][3]=

// Stream of values 2.9 -105.8 -57.4\n3.0 -104.8 -58.6\n3.1 -103.9 -59.7\n3.1 -103.0 -60.2\n3.1 -102.1 -60.8

// Matrix of values
// X Y Z
//
/ / j0 j1 j2

{ {2.9, -105.8, -57.4}, // i 0
{3.0, -104.8, -58.6}, // i 1
{3.1, -103.9, -59.7}, // i 2
{3.1, -103.0, -60.2}, // i 3
{3.1, -102.1, -60.8}, // i 4
};

int i;
int j;

{
// Loop to populate the array matrix
for(i=0; i<5; i++)
for(j=0; j<3; j++)
{

cout<<array[i][j]<<" \n"; //Check array matrix has formed

// It will work up to here then I am lost


}
//ax[5] = array[5][3]; // Make array ax pull off first coloum
{
// for(j=0;j<1;j++);


//j=0;j<3; gives coloums XYZ
//j=0;j<1; gives coloum X rows 0-4 X values
//j=1;j<2; gives coloum Y rows 0-4 Y values
//j=2;j<3; gives coloum Z rows 0-4 Z values


// for(i=0;i<5;i++);
}
}

//cout<<ax[i]; //Check ax array has formed

return 0;
}

Cool.

I have just started to learn C++ and would like to ask for any guidance that could be given.

RTM and practice practice practice.
