in other news I've been doing A Silly like - _what if raytracing in OpenComputers_ (a Minecraft mod that adds Lua-based computers) - could do with some more shades of blue.. or maybe dithering heh.

and then realizing it's slow as heck so making a way to […]

I've been kindof getting back into vanilla(-y) Minecraft as of recent

I'm so used to modded quest packs so this feels a bit weirdly _oh gosh what and how do I do things_ heh :P
Screenshot of a Minecraft world at night, by a lake. There is... - A small crop farm growing wheat, carrots, pumpkins, and sugar cane - A wooden abode extending out from a pier - Another wooden house further inland on a hill A close-up of the first wooden abode from the previous image, floating out in the lake. There's some seating on a porch, an open - mostly empty ground floor, and a small pier extending from the house with a boat floating beside it.

so I just redid my website.. uh I basically wanted to do easings.net, except you can play with the expression and you get more than just JavaScript code (ok well you don't get any CSS bezier curves because heck if I know how to do that)

A screenshot of the easing tool on my website. It is showing the "out elastic" animation curve, described by some expression code. That expression code is transpiled into several different programming languages below - generated Rust, C, C++, and GLSL/HLSL/OpenCL C code are visible here.

..realizing Resolve has a character limit on expressions

sooo... how about working around it by writing code in a sticky note, and eval-ing that :P
A screenshot of Davinci Resolve Fusion's node editor. There is a text node, and a sticky note node, which contains Lua code. The lua code appears to be making rotation matrices. A screenshot of the inspector in Davinci Resolve Fusion. There is a text box with three numbers in it, populated from the expression: loadstring(DotVectorsScript.Comments.Value)()

Some more fancifying things
A screenshot of a custom menu in Balatro. It's graphing how many chips I scored per hand, the number of chips I need to score, and my money over time. On the side is additional info for a single hand, including the cards I played, jokers used, and the blind.

Some tidying up.. moved the options to the top and all the graph labels are nice and aligned now

Been toying around with #balatro modding as of recent - thought it'd be an idea to graph stuff :P

Tinkering on that raytracer's getting a little tiresome when I'm forever at odds with performance now - struggling to get it running decently on anything that isn't a _very_ high end graphics card.

F16 support (to reduce register pressure) doesn't seem to […]

As much as I would like to profile the shader code itself too.. uhh..

That would require me to try figure out how my shader code maps to RDNA3 assembly. There's no fancy debug symbols here.

Hm, apparently I'm being bottlenecked by register counts on that raytracer now - and looks like naga (shader transpiler wgpu uses) doesn't support half-precision floats for now - wanted to try 16-bit floats to try save on vector regs.

Trying to get this performing better is.. an ordeal alright.
A screenshot of Radeon GPU analyzer, showing a graph of wavefront occupancy. The majority of the time is spent at around 60% occupancy, and colored blue to signify it's bottlenecked on VGPRs (vector general purpose registers). A screenshot of Radeon GPU Analyzer, that reads the following: Per-wavefront-resources Vector registers: 72 (72 allocated) Scalar registers: 128 (128 allocated) Theoretical wavefront occupancy The occupancy of this shader is limited by its vector register usage. This shader could potentially run 10 wavefronts out of 16 wavefronts per SIMD. However, if you reduce vector register usage by 2 you could run another wavefront.
