#includeIn this example, we first save the current transformation matrix using pushMatrix(). We then apply a rotation and translation transformation, which would normally affect all subsequent transformations. However, since we saved the previous matrix, we can restore it using popMatrix(). The package library used in this example is unspecified, as the Director class belongs to a specific graphics or game engine.Director director; // Save the current transformation matrix director.pushMatrix(); // Apply a rotation transformation director.rotate(90); // Apply a translation transformation director.translate(10, 20); // Restore the previous transformation matrix director.popMatrix();
