Coding Adventure: Ray Tracing

I tried creating a custom ray/path tracing renderer. Featuring: maths, shaders, and cats!
This project was written in C# and HLSL, and uses the Unity game engine.

Always a good day when a Coding Adventure releases

[willthunder]

You are the Bob Ross of coding with phrases like "Our little raytracer" and I love it.

[HunterHerbst]

It always sounds like Sebastian is explaining all this cool stuff with a massive smile on his face. Like you can just hear it in his voice. And his happiness make me happy in a way. I love your work, keep it up :D

[Khawalidmi]

Whenever Sebastian says "How this works is super simple", I pay extra attention.

[spidermankey]

When others code it is frustrating but when Sebastian codes it looks like he is Ballet Dancing like the world is on 0 difficulty

[LightningFoxHD]

Sebastian doesn't upload often, but when he does you know I'm clicking on it immediately

[MykelGloober]

"Truly one of the artworks of all time."

Couldn't agree more, it's definitely one of them!

[exe]

how in the world did you make this so nice to watch

the catto, the tomato, and your slight sense of humor is simply perfect

[aleksp]

Sebastian is the definition of quality over quantity

[rocketgirl]

MOM! SEBASTIAN LAGUE DROPPED ANOTHER VIDEO! CANCEL THE DENTIST!

[brunoromeroperez]

29:53 "Truly one of the artworks of all time"

"Anyway, what's going on with this tomato?"

I died here

[minerkey]

is it just me, or does Seb sound like hes smiling the whole time as he records

[Josbird]

The juxtaposition between the calm, confident voiceover and the sudden bugs never fails to make me chuckle

[cerealkeepsyougoingeveryda]

The series continues, and I'm very grateful for this Sebastian!

[ymi_yugy]

I can't even begin to image how much work it must have been to write all these visualizations. Keep up the good work.

[shockwave]

That technical difficulty during the FOV part in the intro had me in stitches, unapologetically showing that even though we have the lofty goal of ray tracing we can still have something so trivial trip us up. I just love how incredibly informative as well as entertaining Sebastian is

[LaunchRecap]

I don’t know if I’m disappointed or excited. I was expecting a April fools video but honestly this is the best video released today. ❤

[iankistner]

"Truly one of the artworks of all time. Anyway, what's going on with this tomato?" is easily one of the transitions I've ever seen.

[EdoardoDurbano]

Do I understand anything? No. Do I watch it to the end? Yes.

"my Computer is dying, but i think it looks nice" is my favorite quote xD
