i have a csv file with points, and i need to take that values and ploat within a cube using opengl in cuda . i already plot the points in the cube. but i dont no how it implement in cuda. i need help.

What I have tried:

# include <cstdlib>
# include <ctime>
# include <cmath>
# include <fstream>
# include <iostream>
# include <iomanip>
# include <GL/glut.h>
# include <string>
# include <sstream>
# include <vector>
# include <string>
using namespace std;

glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

glRotatef(xRotated,1.0,0.0,0.0);
glRotatef(yRotated,0.0,1.0,0.0);
glRotatef(zRotated,0.0,0.0,1.0);



glColor3f( 1, 1, 1 );
