RGB rendering is founded on lies and perpetuated by misconceptions about the practicality of spectral rendering. My new blog post series describes a spectral GPU path tracer. Part 1 focuses on how to make it work with existing RGB assets.

I do not claim to know why we are on this planet, but I am very certain we are not born to start a mission where we optimize every single little thing in our lives.
I think it's just not good for the spirit.

I've been bedridden for the last 6 months, unable to work as I try to get a surgeon and insurance lined up for my operation to let me work again.
If you could send a couple dollars, it'd really help. Time isn't on my side here, and waiting is very expensive.

Remember us folks who birthed circle MUD and then smaug, IRC, gzip, and so on?
We are still here.
These big companies want you to think they are tech, and have been so since the start.
Nope, just some piece of shit CEOs who will disappear into the wind as their board deems fit.
It is the people, us.

An unusual blog post today! I've long wanted to see some actual numerical estimates on how good importance sampling is at variance reduction in raytracing, and, failing to find anything like that in the literature, I've ended up deriving my own :)

Had an idea in the shower last night, hacked together a few scripts, and although it's crude, I am happy to say that in-game editor access is quite achievable with Godot!
