I put together a little site for looking up Vulkan enums by name, hex, or decimal :) I hunt for enums like this surprisingly often when developing, so I figured I'd share it around!

I've been working on a new Vulkan renderer for StereoKit! Just over two weeks in, and I've amassed a nice collection of little feature demos :)
Instancing, single pass rendering, stencils, compute, 3D textures, mips, cubemaps, threaded upload, and a whole bunch more. Can't wait to get this into SK!

Just uploaded the code for the little water sim demo I used for v0.3.10's promo video :) Nothing crazy in here, but may be of interest to some people!

Quick sketch in StereoKit, 3drwny on Twitter made a neat gif and I really wanted to touch it! No AO like the original had, but I did slot in some shadowmap stuff I've been working on.

If you're still using Unity for XR, skip the Vendor SDKs and use actually portable OpenXR code like this instead!

I just finished a diet that was quite nice, so I thought I'd share notes! The technique was calorie counting and running a deficit, nice and simple. I can eat anything I want, as long as I budget appropriately!
I spent 90 days, and dropped 152lb -> 142lb. I can see my abs again, nice! :) 🧵

More photos from London, these are all from St. Paul's Cathedral! Delightfully, they let you climb _all_ the way to the top of this one, giving you some rather spectacular views of the city! Also, very windy, and _very_ high up, kinda like a lighthouse.

In my free time I've been noodling with a small app for editing photos via shaders! Basically a shader hot-reload editor plus a reflection powered panel inspector, and on-photo editing tools for certain pre-defined types.
It's been fun to noodle on, and I'm excited for when it's more feature rich!

Whenever I travel, I like to pick up a “trophy” to remember the trip by. I just got back from London, where I got a silver denarius from 213 AD! Valid currency in London at the time.
A denarius was worth about a day’s wages, and this one features the bloodthirsty Roman emperor Caracalla! Neat!
