How do you get three stars on Angry Birds level 1-2?

3-9's a bit tricky. Shoot the red bird at a roughly 45 degree angle towards the top. You will hit the wood and some dice will fall (to maximize score, make sure three dice fall). This should take out the majority of the pigs. Next, shoot another bird towards the large wooden structure and score a lot of damage points and take out the remaining pigs.
