My setup is basically a MacBook Pro connected to an external display😊

Just out of curiosity, did you render your wallpaper?
As in, in Blender or Max or something similar

@RememberMe i wrote a Pathtracer and rendered the picture with it :) needed about 3 Minutes on the Macbook

@SovietStorm oh hey, nice, I've written one too, for my university project.
What all did you put in it?

@RememberMe nothing too fancy. For the most part it‘s guided by „Raytracing in a weekend“ with some changes to optimize speed 😄

@SovietStorm right, I've seen that guide, it's pretty nice.

This is what mine could do, it was seriously satisfying.

@RememberMe wow great job at that 😍
How long did it take to render?

@SovietStorm heh, thanks.
Somewhere between two to four minutes, I think. There's a ton of noise if you look closely, this isn't even close to finished.

@RememberMe wow this is incredible 😍
At some point i am going to try some real time lighting approaches in OpenGL or Metal.
Or learn a thing or two about Photon Mapping 😄

@SovietStorm since you have a path tracer already you can implement photon mapping pretty easily, you literally just have to run the algorithm in reverse once, and then forwards again.

You'll need some kind of efficient spatial data structure to hold the photons though, the standard things are BVHs or k-d trees. Or if you're just doing it for fun, a good old array would do as well :p

@RememberMe i know about those data structures, might give it a go if i have some time 😁
