GLfloat color[6][3]={{1.0,0.0,0.0},{0.0,1.0,0.0},{0.0,0.0,1.0},

{1.0,1.0,0.0},{1.0,0.0,1.0},{0.0,1.0,1.0}};

int tempc[3][3][6];

GLfloat xRot = 10.0f;

GLfloat yRot = 10.0f;

int rotateType=0;

int rotateOK=0;

int rotateRate=50;

int rotate=0;

void drawcube(int cl[6])

{

glBegin(GL_QUADS);

glColor3fv(color[cl[0]]);

glVertex3f(0.14f,-0.14f,-0.14f);

glVertex3f(0.14f,0.14f,-0.14f);

glVertex3f(0.14f,0.14f,0.14f);

glVertex3f(0.14f,-0.14f,0.14f);

glColor3fv(color[cl[1]]);

glVertex3f(-0.14f,-0.14f,0.14f);

glVertex3f(-0.14f,0.14f,0.14f);

glVertex3f(-0.14f,0.14f,-0.14f);

glVertex3f(-0.14f,-0.14f,-0.14f);

glColor3fv(color[cl[2]]);

glVertex3f(-0.14f,0.14f,0.14f);

glVertex3f(-0.14f,-0.14f,0.14f);

glVertex3f(0.14f,-0.14f,0.14f);

glVertex3f(0.14f,0.14f,0.14f);

glColor3fv(color[cl[3]]);

glVertex3f(-0.14f,0.14f,-0.14f);

glVertex3f(0.14f,0.14f,-0.14f);

glVertex3f(0.14f,-0.14f,-0.14f);

glVertex3f(-0.14f,-0.14f,-0.14f);

glColor3fv(color[cl[4]]);

glVertex3f(-0.14f,0.14f,-0.14f);

glVertex3f(-0.14f,0.14f,0.14f);

glVertex3f(0.14f,0.14f,0.14f);

glVertex3f(0.14f,0.14f,-0.14f);

glColor3fv(color[cl[5]]);

glVertex3f(-0.14f,-0.14f,-0.14f);

glVertex3f(0.14f,-0.14f,-0.14f);

glVertex3f(0.14f,-0.14f,0.14f);

glVertex3f(-0.14f,-0.14f,0.14f);

glEnd();

glFlush();

}
