Some days ago I finished "Ray tracing in a weekend" (Peter Shirley) and I'm learning a lot :D
In the new year I will start with "Ray tracing the next week", but there are still some things I want to tackle before that (improve code quality, optimize... it's my first project that is bigger than a codeforces problem solution, a part from the projects at work).
Any sources of wisdom and recommendations are welcome!!

Nvidia makes real time ray tracing and a ehole bunch of graphics stuff beyond our imagination but they can't make a linux driver that actually works well... For ducks sake9

Swear to god if people don't stop calling the new RTX cards true ray tracing I'm going to ring their necks...
It is far from true ray tracing, it's a hybrid with ray trace base technology... Pls stop5 -
WHY THE FUCK! WHY THE FUCKING FUCK! DO I HAVE TO WAIT 3 FUCKING DAYS TO GET A FUCKING VIDEO RENDERED! i didnt buy a new fucking 2080TI for this! WHY THE FUCK DOES THE CPU RENDER THE FUCKING VIDEO!
I mean, we can do fucking REAL TIME RAY-TRACING! And yet, no fucking idiot came to the Idea, "hmm we could let the GPU its intended purpose and dont use the CPU that much." I MEAN, IT HAPPENED, BUT FUCK IT! FUCK ALL OF THIS! FUCKING 74 HOURS!! FOR AN HOUR CLIP!
(Its 4K tho)

New idea: Fuck raytracing for global illumination because you just need too many rays for it to converge
What if we do surfels (to keep the number of probes down and relevant to our scene) and we update the 4x4-ish sized hemisphere irradiance maps not by tracing a single ray per frame per surfel. I have a fast as shit compute shader rasterizer... What if I just raster each surfel each frame? Should be around the same number of pixels as the primary visibility so totally feasible....
Each frame just jitter the projection a bit and voila. Should have extremely high quality diffuse global illumination at well below 1 ms. Holy shit this might just work2 -
I was looking through some shader videos and wanted to see how hard it is to write one, and after some research I am now confused.
Are shades just basically fancy filters like black and white filters and those shitty Snapchat colour filters or is there a particular trait with shaders that diffferes them from filters that I am missing?
I always thought that shaders were all about ray tracing/marching and obtaining the effects that way.2 -
WHICH CRYPTO RECOVERY COMPANY IS LEGIT: HIRE FUNDS RECLIAMER COMPANY
As an architect, every design I create is a mark of trust, trust in materials, trust in my team, and trust in the earth beneath our feet. But nothing could have readied me for the collapse I experienced when that trust was broken from within. I had laboriously built up a $400,000 Bitcoin hoard over several years, a monetary safety net for my business to weather financial tempests and fund future projects. I entrusted its defense to a long-time business partner, a man who I once considered my right arm. That trust fell apart when he betrayed me. It started subtly. I noticed minor discrepancies, delayed logins, emails not returned. Then one morning, I was locked out altogether. He was gone. The phones weren't answered, his office cleared overnight, and my heart pounded in alarm. The electronic safe haven of our hard-won savings was now a fortress without a key, hostage to a ghost. Rage and panic warred within me. I envisioned telling my employees that our future was doubtful because I had trusted the wrong person. Sleepless nights were spent searching the web for miracles. That was when, at an architectural design expo in Milan, I overheard two colleagues discussing FUNDS RECLIAMER COMPANY. Their stories of miraculous crypto recoveries caught my attention like a ray of light piercing a room darkened by shadows. With nothing to lose, I reached out to FUNDS RECLIAMER COMPANY. Their staff handled my case from the very first consultation with the same discretion and precision that I bring to my own cases. They did not handle my case like a transaction but like a delicate form that had to be painstakingly restored. Their cybersecurity experts meticulously tracked my partner's digital footprints, unraveling his complex attempt to hide his trail. Through cutting-edge blockchain tracing and legal action, they slowly dismantled his blockade. I was updated daily, step by step, like progress reports on a skyscraper rising from the earth. Fifteen tense days later, the call came. They had succeeded. The money was back in our firm's possession, intact and secure. Relief washed over me like the unveiling of a completed work of art. FUNDS RECLIAMER COMPANY not only got back money; they got back my hope. They made me realize that even when trust is lost, there are still able hands ready to rebuild. For that, I will forever be grateful.
