+# Name: Xiaoyue Ma
 
-Create a [Shadertoy account](https://www.shadertoy.com/). Either fork this shadertoy, or create a new shadertoy and copy the code from the [Debugging Puzzle](https://www.shadertoy.com/view/flGfRc).
+Shader Link: https://www.shadertoy.com/view/cd3yz2
 
-Let's practice debugging! We have a broken shader. It should produce output that looks like this:
-[Unbelievably beautiful shader](https://user-images.githubusercontent.com/1758825/200729570-8e10a37a-345d-4aff-8eff-6baf54a32a40.webm)
-
-It don't do that. Correct THREE of the FIVE bugs that are messing up the output. You are STRONGLY ENCOURAGED to work with a partner and pair program to force you to talk about your debugging thought process out loud.
-
-Extra credit if you can find all FIVE bugs.

-# Submission
-- Create a pull request to this repository
-- In the README, include the names of both your team members
-- In the README, create a link to your shader toy solution with the bugs corrected
-- In the README, describe each bug you found and include a sentence about HOW you found it.
-- Make sure all three of your shadertoys are set to UNLISTED or PUBLIC (so we can see them!)
+Bug1: Apparently vec to vec2.
+Bug2: In raycast(uv2, dir, eye, ref); we use uv2 instead of uv, uv2 transfer the orignal position to (0,0). When we use uv, the coordinate is wrong.
+Bug3: In H *= len * iResolution.x / iResolution.y; We should / iResolution.y instead of iResolution.x. Cuz we want to generalize the length to the screen size.
+Bug4: In dir = reflect(dir, nor); We should use dir to replace eye, eye is a position but we want the direction from eye.
