LOVR

An open source framework for rapidly building immersive 3D
experiences.

    Designed for VR

    Out of the box you get fast stereo rendering, VR controllers,
    hand tracking, haptics, spatial audio, 3D physics, PBR materials,
    SDF fonts, multiplayer, and more.

  * 

    Super Lightweight

    The entire engine is 1MB and runs on LuaJIT, the fastest JIT
    compiler round these parts. Projects are just folders with
    scripts and assets in them, organized however you want.

  * 

    Beginner Friendly

    You can write 3 lines of Lua and drag and drop a folder onto an
    exe to get a working VR scene. Lua is known for its simplicity,
    making it great for learning.

People are using LOVR for game jams, commercial projects, tools,
education, and VR/3D/2D prototyping. Some daring souls have even
embedded LOVR inside of Unity, ported the engine to other languages,
and gotten it running on tiny microcontrollers. With the power of
LOVR, you can turn virtually any idea into reality.

Starter Projects

  * Hello Virtual World

                function lovr.draw()
                  lovr.graphics.print('hello', 0, 1.7, -1, .5)
                end


  * Spinning Cube

                function lovr.draw()
                  local angle = lovr.timer.getTime()
                  lovr.graphics.cube('fill', 0, 1.7, -1, .5, angle)
                end


  * Hand Tracking

                function lovr.draw()
                  for i, hand in ipairs(lovr.headset.getHands()) do
                    local x, y, z = lovr.headset.getPosition(hand)
                    lovr.graphics.sphere(x, y, z, .1)
                  end
                end


  * Audio

                function lovr.load()
                  song = lovr.audio.newSource('darude.ogg')
                  song:play()
                end


  * Skybox

                function lovr.load()
                  sky = lovr.graphics.newTexture('sky.hdr')
                end

                function lovr.draw()
                  lovr.graphics.skybox(sky)
                end


  * 3D Model

                function lovr.load()
                  model = lovr.graphics.newModel('monkey.gltf')
                end

                function lovr.draw()
                  model:draw(0, 2, -3, 2, lovr.timer.getTime() * .2)
                end
