LÖVR

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 LÖVR for game jams, commercial projects, tools, education, and VR/3D/2D prototyping. Some daring souls have even embedded LÖVR inside of Unity, ported the engine to other languages, and gotten it running on tiny microcontrollers. With the power of LÖVR, 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
