Moving from Rust to C++

At WWDC, Apple introduced Metal shader converter, a tool for converting shaders from DXIL (the main compilation target of HLSL in DirectX12) to Metal. While it is no doubt useful for reducing the cost of porting games from DirectX to Metal, I feel it does not move us any closer to a world of robust GPU infrastructure, and in many ways just adds...

Finding the optimal Bézier path to fit some source curve is, surprisingly, not yet a completely solved problem. Previous posts have given good solutions for specific instances: Fitting cubic Bézier curves primarily addressed Euler spirals (which are very smooth), while Parallel curves of cubic Béziers rendered parallel curves. In this post, I...

Vello is a new GPU accelerated renderer for 2D graphics that relies heavily on compute shaders for its operation. (It was formerly known as piet-gpu, but we renamed it recently because it is no longer based on the [Piet] render context abstraction, and has been substantially rewritten). As such, it depends heavily on having good infrastructure...

This post reflects a bit on 2022 and contains wishes for 2023. It mixes project and technical stuff, which I write about fairly frequently, and more personal reflections, which I don’t.

There’s a lot of new interest in open source text layout projects, including cosmic-text, and the parley work being done by Chad Brokaw. I’m hopeful we’ll get a good Rust solution soon.
