Setup

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.

Solution

Team members: Joanna Fisch, Rhuta Joshi

Bugs:

Line No.	Artifact/Issue that helped in identification	Correction
99	Compile time error, vec not found	Replaced vec with vec2
102	Made the image appear flat or with incorrect resolution	Passed remapped uv2 instead of uv to rayCast function
11	Everything appeared stretched along x axis	`iResolution.x/iResolution.x` replaced with `iResolution.x/iResolution.y`
76	Reflection not working, spheres looked flat shaded	Was reflecting eye about normal instead of dir about normal
18	Disappearing floor plane around edges of spheres	Very small value of max ray steps, updated from 64 to 256
