# lab02-debugging

Team Members: Yichen Huang, Kevin Du

- Declaration of vec2 uv2, I found this bug since it was a compile error that showed me the line, it was a syntax error and I fixed it by correcting the syntax.
- Passing uv into raycast function. Someone told me about this and I changed it from uv to uv2 since I didn't notice it.
- Multiplying H by iResolution.x / iResolution.x seemed incorrect and I thought it should be the aspect ratio so I changed it to iResolution.x / iResolution.y.
- To debug reflection, I started by making sure the reflection direction was correct. I saw that it was wrong since we were reflecting the position, not the direction.
- I saw that the checker floor in the output was a long than my output, but the floor plane was really big, so I increased the march steps from 64 to 256 so the ray could march longer.
