בסוף שנה אני צריך להגיש פרוייקט ב OpenGL שנכתב בסביבת VCpp, כחלק מהתירגול עשיתי סביבון שמשנה את כיוון סיבובו ע"י קליל העכבר (קליק ימני-ימינה ולהפך)

קוד:

 
#include <GL/glut.h>
GLfloat vertices[][3] = {{2.0,2.0,-2.},{-2.,2.,-2.},{2.,2.,2.},
{-2.,2.,2},{2.,-2.,-2},{-2.,-2.,-2.},{2.,-2.,2.},{-2.,-2.,2},{0.5,4.,-0.5},{-0.5,4.,-0.5},

int direction = 1;

void polygon(int a, int b, int c , int d)
{
glBegin(GL_POLYGON);
glVertex3fv(vertices[a]);
glVertex3fv(vertices[b]);
glVertex3fv(vertices[c]);
glVertex3fv(vertices[d]);

if(button == GLUT_RIGHT_BUTTON && state == GLUT_DOWN)
direction = 1;
}
