FAQ

Avoyd is a voxel editor and PBR path tracer. It is in active development. You'll find more information, including features and user documentation on the official Avoyd website.

Avoyd started as a game. We started working on Avoyd in 1999, selling the game as shareware. It was, to our knowledge, the first voxel game with an entirely editable environment (destruction and building). After a 10 year pause we restarted development in 2012, rewriting the game engine from scratch and evolving the concept to take advantage of technological advances. The new version of Avoyd is inspired the original Avoyd 1999 and Quite's haunting zeo-x-s demo, Rez (Area 4 in particular), FPSs we've liked to play like Unreal Tournament, Descent, and much more.

The game is unfinished and its development is currently on hold but you can play the prototype we include (hidden) in the voxel editor.

The best place to buy your licence and download Avoyd is on this website's Products page.

Alternatively, you can use itch.io. Steam: we plan to release Avoyd on Steam in the future, when we have completed its core feature set. This is likely some time away. When we get on Steam, and if we are able to, we will give Steam keys to people who had already bought Avoyd.

Minimum Requirements

Avoyd runs on our in-house voxel game engine written in C++ using OpenGL, and Vulkan for the GPU renderer. This is partly why the download size is small. The engine is developed by Doug Binks and Juliette Foucaut.

To follow our progress with the game technology, see the Game Tech topic on our devlog, our public posts on Patreon and follow @dougbinks and @juulcat on Mastodon.

We open source parts of our engine:

• Runtime Compiled C++ for rapid iteration

• enkiTS, my lightweight multithreading task scheduler - further information can be found under our devlog's enkiTS topic

• enkiMI, our Minecraft Importer library

• IconFontCppHeaders, our script to generate Font Awesome icon fonts header files for the GUI

• imgui_markdown, markdown for Dear ImGui

We use third-party open-sourced software listed below. Many thanks to the authors and maintainers of these libraries.

• OpenGL for Graphics

• GLFW for platform independent OpenGL Window & Input handling

• GLEW OpenGL Extension Wrangler Library

• OpenAL Soft for Audio

• RakNet for Networking (using just the low level network code)

• NanoVG for HUD elements

• Dear ImGui for the GUI

• ImGuizmo for 3D manipulation in the Voxel Editor

• LZ4 for compression

• A modified version of SJSON for settings files

• A modified version of the Ray Slope Intersection source from the article on Fast Ray/AABB Overlap Tests.

• Microprofile for real-time profiling - see enkiTSExamples for a sample usage.

• jo_gif GIF writer

• open game tools for reading MagicaVoxel .vox files

• libcurl

• robin-hood-hashing for hash map

• MurmurHash3 hash functions

• xxHash hash functions

• uint C# xxHash, we derived our C++ uint32_t xxHash implementation from this C# example

• dbgtools platform independent debug functions

• stb single-file libraries for C/C++

• TinyEXR for OpenEXR images support

• TinyglTF for glTF .glb export
