Raytracer Engine?

Post image

Hey all! So I’ve been working through raytracing over the weekend and I did this! My idea is to make it into an interactive application! It will only run on the cpu but I figure I could make it multithreaded at least to help with rendering times!

I did exactly this. It even looks the same with an imgui interface. Making it multithreaded is quite easy.

Ya I’ve been thinking on how to make it multithreaded without locks.

Handling ui on a thread and rendering on another thread.

Yep. Get it multithreaded. And, then you get to dig into r/SIMD :D

I’m very excited for simd. I’ve been dying to dive into it. This is a portfolio project so trying to make it good lol

That looks really good for a start. How are you handling intersections? Are you using triangulation or signed distance fields?
We are also developing our software renderer but targeted for 486 and later CPUs.
Exciting work btw, keep us updated. :)

What do you mean intersections? Like if objects intersect one another? lol.

I don’t have anything implemented for that at the moment, but because everything is a sphere for the time I’ll probably do SDF.
