+
+### Performance Analysis
+
+#### Time spent in each stage
+
+To give guarantee enough operations for each step, all the features are turned on.
+
+![breakdown](img/breakdown.png)
+
+We can clearly see that the more space an onject took the window, the more time is spent on rasterization. Rasterization in our implementation is of heavy work.
 
-### (TODO: Your README)
+#### Performance impact of backface culling
 
-*DO NOT* leave the README to the last minute! It is a crucial part of the
-project, and we will not be able to grade you without a good README.
+![fps](img/fps.png)
 
+As we can see, there's no significant improvement after we add backface culling (even drawbacks). This indicate that in our naive implementation of backface culling (mainly the backface detection part) has more overhead than contribution in these models.
