Noiselund@noiselund.bsky.social · 7mo agoI started doing these stupid songs three years ago today. To celebrate I made this love letter to all our favorite hack frauds @redlettermedia.com Huge thanks to Josh Robert Thompson @jackpackard.bsky.social @sgtzima.bsky.social and Josh Davis for helping out! www.youtube.com/watch?v=hQqi...

28 Years Later: The Bone Temple was fantastic! Less weird, experimental cinematography than the earlier film, but it’s way more focused. Also Samson rules.
My "No Graphics API" blog post is live! Please repost :) www.sebastianaaltonen.com/blog/no-grap... I spend 1.5 years doing this. Full rewrite last summer and another partial rewrite last month. As Hemingway said: "First draft of everything is always shit".
No Graphics API — Sebastian Aaltonen

Tired of twitchy dogfighters? It's time to command something with weight. 🚀 In Warfleet Captains, you don't fly a fighter jet—you take direct command of massive Frigates, Destroyers, and Battleships. This is tactical, heavy-metal fleet combat. #indiedev #gamedev #spacegames #scifi #steam

The post on using spatial hashing with raytraced ambient occlusion attracted quite a bit of interest so I expanded it into a blog post to discuss how it works behind the scenes to both reduce the noise and its cost. interplayoflight.wordpress.com/2025/11/23/s...
Spatial hashing for raytraced ambient occlusion
Subdividing a 3D space into cells or voxels and using positional and/or directional information to directly index into it is a popular method to store and access local data, typically using 3D text…

Kostas Anagnostou@kostasanagnostou.bsky.social · 9mo agoDid a quick and dirty implementation of a spatial hash structure to speedup RTAO, ray results are stored in cells indexed by pos/normal/cell size and after storing a few rays occlusion can be queried from the cell instead of raytracing it. 3x faster raytraced AO for that scene with no denoising.
Capsaicin is not just for tacos, it's also our developer rendering framework! v1.3 is out now: 🌶️ Added heat with GI-1.2, which includes multiple-bounce indirect lighting. 🌶️ HDR support with spicier tone mapping. And much, much more: gpuopen.com/learn/gi-1-2...
Introducing AMD GI-1.2 with multibounce indirect real-time rendering - AMD GPUOpen
AMD GI-1.2, our real-time Global Illumination solution, is available now as part of the AMD Capsaicin Framework v1.3.

Double Fine@doublefine.com · 9mo ago🚨 "The Making of Double Fine's Keeper" is now available! 🚨 Many of you have been asking for this one; we're happy to say the cameras continued to roll here at the studio during Keeper's development. Come see how this very special game came to be, from the team themselves! 😊 youtu.be/1OOfRTfMnx0
I went to meet the 'Rockstar 31', the developers who were suddenly fired from their work on GTA 6 for what the studio has described as gross misconduct. That's not what the workers call it though. They have another couple of words they prefer to use: union busting. www.youtube.com/watch?v=c9nO...

I've got a new blog post for all of you fine folks! It runs through the additions to D3D12 since it was released, and finishes up with some of the things that have changed for me personally in my code. (And yes it's really been 10 years 👴). therealmjp.github.io/posts/ten-ye...
Ten Years of D3D12
For those of us that have been using it from the start, it can be hard to believe that Direct3D 12 has been around for nearly ten years now. Windows 10 was released on July 29th 2015, and D3D12 has be...
