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.

That probably means a lot of testing that we don’t see. I’m a Java backend developer and writing some simple endpoints for say a Spring Boot server means first write the code that handles a request and then a bunch of tests which usually takes a large portion of the time.

He also gives the impression that he's pretending to come up with these ideas on the fly, together with the testing we don't see, it just becomes more of an ASMR parody. People worry about AI not attributing their creations to human generated training data and here we have a 1M+ YT channel blathering on as if he didn't lift shader code from open source projects like Blender or a million other places or even inspiration from any source. Sure, okay Sebastian - what have you woke up and just randomly thought of to code today? lol

It’s just the Scandinavian accent. It’s especially strong for Danish people, who often sound like they are smiling. Evidence for this is that I thought Lague was Danish before I checked the channel info, originally just to check if he might be Scandinavian. This accent results in a “happy” register in English. That being said it requires some level of happiness or concerted effort to sound like this. I assume it’s a bit of both.

I love how you walk through stuff like this. You get the audience to ask, "What is the next natural step?" and give them the breathing room to think of an answer. Then you show them what you came up with and sort of hint at why it is a useful concept more generally without saying it explicitly. Your videos are simply fantastic at getting people (specifically me) to think through complex problems in small rational steps. Bravo. Keep it up!

A quick note about the rejection method you used for the random direction originally, while it is true that about half of the time it will find a good candidate, so on the CPU it would only run on average less than 2 times, on the GPU threads are done in groups of 32 (NVIDIA) or 64 (Intel, AMD), and the threads in one of these groups can only continue once all of them does. I did some tests and that results in 6 or so iterations before exiting on average on 32 thread systems.

13:00 You want to create points using a distribution in (x,y,z) that is only a function of (x^2 + y^2 + z^2) = r^2 (that means it has no dependence on direction, which means the points will be evenly spaced across the surface of a sphere). If we take x, y, z separately, the resulting distribution f(x, y, z)dx dy dz = f(x)dx \* f(y)dy \* f(z)dz (this is because the three are independent (because we calculated them separately), so the probability of finding our output position in the range (x, y, z) -> (x+dx, y+dy, z+dz) is equal to the probability of finding x in that range, times the probability of finding y, in that range, times the probability of finding z in that range. Like how the probability of flipping a coin and getting heads three times is the probability of getting heads once, times the probability of getting heads once, times the probability of getting heads once) Intuitively, it seems that we should take x, y, z from the same distribution (because it's independent of direction, we can't treat different directions differently). Applying these, we see: f(r^2) = f(x^2 + y^2 + z^2) = f(x^2)\*f(y^2)\*f(z^2) What type of function is defined by f(a+b) = f(a)\*f(b)? An exponential. So we find our distribution must be f(r^2) = exp(-r^2), which is a normal distribution. I hope that helps, if I have explained anything badly please say so!

I think I remember someone doing a straight poisson distribution lookup to a table of pre-calculated coordinates for some of these ray directions. I think the idea was to get solid randomness cheaply as you were looking them up instead of calculating them. It was a disk and for better randomness you could just keep rotating the disk. (for say different ray hits or frame numbers) I didn't do this myself but its a memory of something that might have happened. :D

This is amazing. Filled with detail and excitement as you explain, it makes as I want to do it as well. Although could as well be a tutorial, it seems so entertaining and interesting watching what would happen. I subscribed and would like to follow and enjoy while you talk of the capabilities to accomplish. I did not know it could do so much, the programs. Thank you for making this and explaining along the way.

This is the exact kind of thing that I love about programming. I recently made my first pathfinding program in pygame (using Sebastian's A* video), and seeing it work was the best feeling. I feel like making a game would give you that every once in a while, but with little experiments the whole goal is to get a single system working well.

This is just a frivolous ammount of liquid GOLD! Wh-what the hell? I have been following you for a long time, but this Render Coding was AMAZING! I think it's been five years since I started modeling for a living in 3D and I, of course, understand how ray tracing works, but this level of detail was beyond my expectations, I learned a lot today! Thank you very much!!

Hey man just wanted to post a comment to express my love for your videos. Im currently in school studying software development but my love for programming and technology goes beyond that. I'm not the smartest guy and I'm not going to pretend to understand everything you do or say. But man I've learned ALOT. So far the most fascinating thing you taught me is the HOW math is actually used in creating all sorts of things. I've always heard that math is important but I never got an explanation for why or how. I appreciate and love everything you do and I hope you continue making videos like this for a long time. Much love ❤
