Introduction

G'day, and welcome to Hotham! 👋

Hotham is an attempt to create a lightweight, high performance game engine for standalone VR headsets, like the Oculus Quest 2.

It's primarily aimed at small (1-5 person) teams of mostly technical folk who are looking to create VR games, but find existing tools cumbersome to work with. You can learn more about the project in the FAQ or by checking out our talk at the Rust Gamedev Meetup.

Getting started

Hotham is a complex project with many moving parts! Have no fear - we've written an easy to follow Getting Started guide that will have you running our example application in no time. Head on over to getting started to.. get.. started.

Sponsoring

Hotham's development is only possible thanks to the support of the community. It's currently being developed on full time by @kanerogers If you'd like to help make VR development in Rust possible, please consider becoming a donor. 💗
