+I believe I found all 5 bugs.
+
+The first was on line 97:
+  - This ndc conversion tried to use a vec class instead of vec2
+
+The second was on line 100:
+  - I simply used the same uv vec2 for all uv usages, so no need for uv2
+
+The third was on line 11:
+  - The aspect ratio calculation used the screen width divided by width instead of width divided by height
+
+The fourth was on line 18:
+  - The number of ray marching iterations was too small so I increased to 128
+
+The fifth was on line 75:
+  - The eye, or camera position, was passed as the incident ray direction in the glsl reflect function. Instead I pass the actual direction of the incident ray dir
+
+To find all these bugs, I simply went in sequential order in terms of code execution: I started with the main function, then moved to raycast and sdf3D and march etc.
+Luckily, I have become very familiar with ray casting and marching, so finding the bugs only required me to look through the code and notice anything that
+seemed out of place. In something I was less familiar with, I would probably have had to start incrementally testing the functions to understand the output.
