Makepad is a new live-coding environment from Rik Arends that focuses on shader development for virtual reality. The code is open source and is an interesting use of Rust for both native builds and WebAssembly in the browser.
This new tool from Ada Rose Cannon allows developers to test immersive augmented reality experiences in virtual reality headsets. Because most creators don't have access to relatively expensive AR rigs, this tool enables web-style cross-platform development for many more people.
Continuing our trend of cute experiences with animal-ish characters, Pet me! is a WebXR experience where you pet a critter. The code is freely available along with 3D models that include the "minimally viable cat".
Sol Attrition from Rye Terrell was announced this week and it might give Moonrider a bit of competition for the best free game on the immersive web. The author mentioned that they're using the nicely maturing regl project to write efficient WebGL code.
On the topic of efficiency, WebXR specification co-editor Brandon Jones published a mini-tutorial that covers essential methods of optimizing 3D assets for mobile VR and AR devices. If graphics coder terms like "draw calls" and "backface culling" are unfamiliar (or maybe a little daunting) then this gentle introduction could be just what you need to smooth out your crunchy immersive web project.
