GitHub - alektron/imgui-odin-backends: A custom backend for 'Dear ImGui' written in Odin A custom backend for 'Dear ImGui' written in Odin. Contribute to alektron/imgui-odin-backends development by creating an account on GitHub.

I wrote a custom Dear ImGui backend for Windows/DirectX in Odin. With thin abstraction layer to allow easy extension for more platforms/renderers:

#imgui #DearImGui #Odin #Odinlang

I use ORMs when writing programs, raw SQL when doing analysis, debugging, or database admin.

The problem with raw SQL queries in code is that a) they don't compose well, and b) I still need to convert rows into objects somehow.

I finally sat down to write about what I learned building a Volumetric Lighting effect for the web

In it, I detail how to blend raymarching with post-processing to create beautiful atmospheric light to elevate your next WebGL project

odin-c-bindgen can now create constants from C macros

New blog post! "Load store conflicts", in which we look at some performance sensitive code that has surprisingly dramatic performance swings based on the compiler and the microarchitecture used. Reposts appreciated!

Four vector icons: a cream-coloured rabbit, green trees, a crimson bird with a white eye, and a silver cloud with raindrops in different shades of blue

part a: a mix task that will traverse /assets/ (or anywhere else you point it) for svg images of any size and complexity, and merge them together into a sprite sheet in /priv/static/assets/. ➜ mix phoenix_svg_sprites ➜ [info] Successfully generated SVG sprite sheet at priv/static/assets/sprites.svg the sprite sheet contains all of the processed svgs, stored as <symbol />s addressable by ids derived from the processed svg's filenames. bird.svg and rain.svg become: <svg> <symbol id="bird"><path d="m1154.3... <symbol id="rain"><path d="m1047... </svg>

part b: a phoenix component, <.sprite />, that will render the specified svg sprite in your heex template, the same way you might render a heroicon with core component's <.icon />. the four example sprites at the top of this page are rendered with this code: <.sprite icon="animal" class="animal" /> <.sprite icon="nature" class="nature" /> <.sprite icon="bird" class="bird" /> <.sprite icon="rain" class="rain" /> css classes are applied to the examples to allow for specific colour styling. however, an svg's internal fill, stroke, and other colour values will be preserved, and you can also use currentColor to colour your sprites dynamically through the text colour of a parent element. default tailwind size classes are applied automatically, but you can apply arbitrary classes and other attributes as well.

I just published my first Elixir + Phoenix LiveView package: Phoenix SVG Sprites!

Merge all of your SVG assets into one file, and display them individually, just like you do with <.icon />.

This is my own personal follow-up to @flohofwoe.bsky.social's classic article "Handles are the better pointers"

Hi Karl, I recently picked up Odin (and your book).
I'm interested in making games/apps and generally playing with graphics APIs (webgl / wgpu / vulkan / metal) on desktop and wasm (I got two PRs accepted this week for fixes in the "core:sys/wasm").
Feel free to add me to the list.

A list of images being displayed in the new app I'm developing, zooming, filtering by name and picking color.

New application window right after launch, with text explaining you have to drag and drop images or folders on it.

I couldn't find a basic and fast assets viewer for browsing and searching our growing collection.

Godot 4.4-rc1 being just released, it was time to implement one.

It's so fun how versatile Godot can be.

Given how useful it is for us, I'm thinking of releasing it to more people.

We decided to play with small prototypes, the first one is about some RTS melee movements. You can try it on games.openhood.com/blog/2025/2/...

Been reminded today that NIFs taking more than 1ms should be flag to run on "dirty schedulers" to not block regular #erlang / #elixirlang processes scheduling… and that is one macro away in Rustler: #[rustler::nif(schedule = "DirtyCpu")] for CPU intensive, "DirtyIo" for IO intensive functions
