g3d

groverburger's 3D engine (g3d) simplifies LÖVE's 3d capabilities to be as simple to use as possible.

1. Download the latest release version.
2. Add the g3d folder to your LÖVE project.
3. Add local g3d = require "g3d" to your main.lua file.

The entire main.lua file for the Earth and Moon demo is under 30 lines:

local g3d = require "g3d"
local earth = g3d.newModel("assets/sphere.obj", "assets/earth.png", {4,0,0})
local moon = g3d.newModel("assets/sphere.obj", "assets/moon.png", {4,5,0}, nil, 0.5)
local background = g3d.newModel("assets/sphere.obj", "assets/starfield.png", nil, nil, 500)
local timer = 0

function love.update(dt)
    timer = timer + dt
    moon:setTranslation(math.cos(timer)*5 + 4, math.sin(timer)*5, 0)
    moon:setRotation(0, 0, timer - math.pi/2)
    g3d.camera.firstPersonMovement(dt)
    if love.keyboard.isDown "escape" then
        love.event.push "quit"
    end
end

function love.draw()
    earth:draw()
    moon:draw()
    background:draw()
end

function love.mousemoved(x,y, dx,dy)
    g3d.camera.firstPersonLook(dx,dy)
end

• Textured 3D model rendering
• OBJ file loading
• Perspective and orthographic cameras
• Custom vertex and fragment shader support
• Basic first-person movement and camera controls
• Lightweight collision queries
• Simple, commented, and organized

The g3d wiki explains the camera, models, custom shaders, collisions, and other topics in more detail. The original forum post has more project history and discussion.
