+V eneom od prejšnih vajah uporabite naslednji podprogram in ga prijavi kot GLUT podprogram, 
+ki se izvede pri spremembi velikosti okna.

+void reshape(int w, int h)
+{
+  GLdouble width = w, height = h;
+  GLdouble left, right, bottom, top, znear, zfar;
+
+  if (w > h)
+    {
+      left = -width/height;
+      right = width/height;
+      bottom = -1.0;
+      top = 1.0;
+    }
+  else
+    {
+      left = -1.0;
+      right = 1.0;
+      bottom = -height/width;
+      top = height/width;
+    }
+  znear = -1.0;
+  zfar = 1.0;
+  glViewport(0, 0, w, h);
+  glMatrixMode(GL_PROJECTION);
+  glLoadIdentity();
+  glOrtho(left, right, bottom, top, znear, zfar);
+  glMatrixMode(GL_MODELVIEW);
+  glLoadIdentity();
+}
+}}}
+Kakšna je lastnost take spremembe okna? Začetno okno izrišite v velikosti 500x300.
