Loved the intro but that code sample could've used proper variable names.

Hi, I’m the author of the article. Thanks for the feedback. I cleaned up the shader code to make it easier to read/follow. If anything’s still unclear, feel free to comment on the post and I’ll try to clarify.

Would have been awesome if there was step by step visualization where simple color transforms slowly upgraded until you get final result for easier understanding of what each thing is doing.

Otherwise quite hard to visualize changes in you head.

I’ve pushed an update to the post with more implementation details, and I also cleaned up the shader code to make it easier to read/follow. If anything’s still unclear, feel free to comment on the post and I’ll try to clarify.

Exactly. Like someone stated, it was a bit like "draw the rest of the fucking owl"
