Add support for importing ambisonic WAV files and 24/32 bit PCM WAV files. The standard ambisonic format used internally in LÖVR is ACN channel ordering with SN3D normalization. Anything else will be converted to this form. There are a few restrictions and assumptions: - Only 1st order ambisonics are supported. They need to have 4 channels. - They can be in AMB format (Furse-Malham order/normalization), detected via WAVE_EXTENSIBLE GUID. - Any other 4 channel file is assumed to be in "AmbiX" ACN/SN3D format. - It seems that most ambisonic files in the wild that claim to be AmbiX are just 4 channel WAVs without any metadata. - This means that non-ambisonic 4 channel WAVs could ambiguously be mistaken as ambisonic. This is incurred as a limitation of LÖVR. - Ambisonic files can not currently be played back. SteamAudio currently has numerous bugs with this. - Perhaps it would be possible to write an ambisonic rotator/panning decoder to use as a default implementation. |

LÖVR
A simple Lua framework for rapidly building VR experiences.
You can use LÖVR to easily create VR experiences without much setup or programming experience. The framework is tiny, fast, open source, and supports lots of different platforms and devices.

Features
- Cross-Platform - Runs on Windows, Mac, Linux, Android, WebXR.
- Cross-Device - Supports Vive/Index, Oculus Rift/Quest, Pico, Windows MR, and has a VR simulator.
- Beginner-friendly - Simple VR scenes can be created in just a few lines of Lua.
- Fast - Writen in C99 and scripted with LuaJIT, includes optimized single-pass stereo rendering.
- Asset Import - Supports 3D models (glTF, OBJ), skeletal animation, HDR textures, cubemaps, fonts, etc.
- Spatialized Audio - Audio is automatically spatialized using HRTFs.
- Vector Library - Efficient first-class support for 3D vectors, quaternions, and matrices.
- 3D Rigid Body Physics - Including 4 collider shapes, triangle mesh colliders, and 4 joint types.
- Compute Shaders - For high performance GPU tasks, like particles.
Getting Started
It's really easy to get started making things with LÖVR. Grab a copy of the executable from https://lovr.org/download,
then write a main.lua
script and drag its parent folder onto the executable. Here are some example projects to try:
Hello World
function lovr.draw()
lovr.graphics.print('Hello World!', 0, 1.7, -3, .5)
end
Spinning Cube
function lovr.draw()
lovr.graphics.cube('line', 0, 1.7, -1, .5, lovr.timer.getTime())
end
Hand Tracking
function lovr.draw()
for _, hand in ipairs(lovr.headset.getHands()) do
lovr.graphics.sphere(vec3(lovr.headset.getPosition(hand)), .1)
end
end
3D Models
function lovr.load()
model = lovr.graphics.newModel('model.gltf')
end
function lovr.draw()
model:draw(x, y, z)
end
You can try more examples in your browser on the docs page.
Building
You can build LÖVR from source using CMake. Here are the steps using the command line:
mkdir build
cd build
cmake ..
cmake --build .
