Switched from ImGui to SwiftUI

Peak found in Amsterdam’s biggest MINISO

-- JOB SEARCH POST/RT APPRECIATED -- Hello everyone! I am available for work (full time position/internship) anywhere in the world with priority going to the EU, starting June 2026. 🧵

Raytraced sun shadows using Metal intersector. Runs like shit because I have an M2 Mac Air which doesn't support hardware raytracing, hopefully I get to upgrade soon so I can get mesh shaders execute indirect and hardware RT...

GPU driven culling using Metal ICB

Clustered Light Culling on iPhone 13

Bugged cluster culling aesthetic

Messing around with Metal + iOS, optimizing this for mobile is gonna be fun

Will be doing a 24h livestream for charity tonight at 6pm Paris time with Téléthon, donating for research against various diseases and to hospitals. At twitch.tv/rainbowpikmiin See you there!

Game engine now has an asset cooker and it works very well!

First ReSTIR test using 16 reservoir proposal samples (right image) compared to uniform direction sampling and ignoring indirect light (left image) with many spread out lights (~3k light-emitting voxel faces here). Quite insane noise reduction going on in here!

This has to be the nerdiest photo I've ever taken.

Branched off my engine, focusing on taking another attempt at making my dream game Working hard and hopefully I can have a player controller scripted in AngelScript with some collisions and whatnot

Turns out properly waiting on both device and host instead of just device can really save lives

Finally getting down to doing some multi-queue stuff, and so far... fuck man D3D12 docs on resource ownership is not helping me at all lmao

How does one even befriend an artist and convince them to help you make your game with your clunky custom engine art tools

Hot take, I think it's a bit of a shame we don't have API level mipmap generation. I mean Metal has it with MTLBlitEncoder::generateMipmapsForTexture, but it'd allow vendors to make use of their architecture-optimized single pass downsampler (also not sure NVIDIA has one)

Been doing some D3D11 work for nostalgia and to help a friend make their game and jeez, I'm missing modern graphics API copy commands, wtf do you mean I can't use CopyResourceRegion in D3D11?

Turns out I was wrong, I can still use Metal Shader Converter even for D3D11....... yes...... good.....

Helping a friend out to make their D3D11/Metal RHI and I'm gonna have to play around with spirv-cross for the first time to get HLSL -> MSL with no bindless

The fact ImGui has issues with high DPI lowkey makes me crazy but at least I'm working on something nice

Guys, I have a graphics prog job interview on thursday, give me your best job interview tips

The improved SSR in godot 4.6

My new blog post is out! In this new post I go into detail in how I implemented my D3D12/Vulkan/Metal RHI in my game engine Kaleidoscope. Link in replies!

Decided I'd merge my renderer into my engine since they were branched But before hand I decided to do some editor stuff, and I am additionally working on a Gigi like "render graph as a data asset" system... Will keep you guys updated

After quite a bit of work, I am finally done with the first blog post about ocean rendering! You can find it here: rtryan98.github.io/2025/10/04/o... I've also decided to create a video to showcase the ocean simulation in motion: www.youtube.com/watch?v=0OXm...

For the people who are interested, I made a discord server for my game engine! If you wanna come chat, roast my code or just talk programming and showcase your own stuff, feel free to join Link in replies

Renderer is now fully functional on Mac + Metal!

Also yes I’m porting my engine to Mac and Metal3

Metal devs -- has anyone achieved ExecuteIndirect emulation with Metal Shader Converter? I know I can write an MSL kernel to go from indirect commands -> Metal ICB, but for MDI I'm mostly curious how I fetch DrawID in HLSL.

Been playing some Ghost of Tsushima and HOLY FUCK

Welp, just finished my last day at Ubisoft

Some people think the next step in graphics is work graphs, some others think real-time PT I want the adoption of ResourceDescriptorHeap on every modern platform (PC + Console) by 2026 otherwise I’m reconverting to web development

I need to move to a country where people actually give a shit about living together and building a community rather than being egotistic and individualistic fucktards. Case in point : Parisian cyclists.

I'm probably the only person ever to care about the aesthetics of my GitHub profile It's cutesy af now though ngl heheheheheheh...

I was bored so I made a thing You can now spoof steam playtime using another .exe github.com/AmelieHeinri...

Honestly Odin is a sick ass programming language that I wish I could use more

Also fyi I'm going to GPC in Breda, Netherlands in november :D Come say hi and talk about graphics!

Pros and cons of living in Montpellier Cons: summer feels like living in hell Pros: there’s a TGM3 arcade in the city center

Downloading pre-compiled shaders on PC???? devblogs.microsoft.com/directx/intr...

Got IBL and bloom added in my renderer Oh also I’m 19 today. Yay!

Hey bsky o/ any recommendations on platform independant texture compressors for bc5-bc6-bc7-astc? So no NVTT

Implemented Im3D in my engine and added a sample to showcase how to use it :D

Went on a little sidequest and implemented device generated commands

The idea of "not talking politics" sounds lovely until you realize that your politics are "nobody should starve" and theirs are "have your family exterminated and you thrown in a concentration camp", but you're both agreeing joyfully that Mario Party really does suck.

Nothing makes me more uncomfortable than having to take my gaming laptop, my only computer, in a train to do some work That little guy will blow air like an airplane motor and yet it still can't do RT hard shadows on Sponza @ 1080p under 2ms It is sad to say I have to save up for a Macbook Pro

Losing my mind trying to denoise stochastic RT shadows this shit is HARD

Hey BlueSky! I wrote my first ever blog post in a while, talking about how I built my RHI for my game engine Kaleidoscope. Link is ⬇️

Often, I'm wondering how many amazing work from cool minds we collectively miss because we decided that everyone need to throw all their energy and waking moment tied at work because some people decided we need money to live.

After a few months of Slang usage I switched back to HLSL I appreciate the effort to make something uniform for every API but realistically you will have to do divergence shit for bindless and whatnot Also compiler was a bit unstable in my experience…
