Step 7: Drawing a Face

•Use vector form of primitives and attributes

void face(int a, int b, int c, int d)

{glBegin(GL_POLYGON);

glColor3fv(colors[a]);

glVertex3fv(vertices[a]);

glColor3fv(colors[b]);

glVertex3fv(vertices[b]);

glColor3fv(colors[c]);

glVertex3fv(vertices[c]);

glColor3fv(colors[d]);

glVertex3fv(vertices[d]);

glEnd(); }
