My Debugging Scene

1. Line 97: There was a syntax error where a vec2 was accidentally written as vec.
2. Line 100: uv was fed into raycast instead of uv2
3. Line 11: Height was not being multiplied by correct aspect ratio. Switched to H *= len * iResolution.x / iResolution.y
4. Line 18: Increased iteration count in march(...) to 256 to allow all parts of the floor to be hit.
5. Line 75: reflection was erroneously done about eye and nor rather than dir and nor.

Create a Shadertoy account. Either fork this shadertoy, or create a new shadertoy and copy the code from the Debugging Puzzle.

Let's practice debugging! We have a broken shader. It should produce output that looks like this: Unbelievably beautiful shader

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.

• 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!)
