Development

Due to rapid changes to 3Dream I am sometimes working on a separate beta branch.

Documentation

Undocumented features are subject to change. They will receive a proper documentation once finished.

Documentation hosted on GitHub

Emmy-love-api recommended for proper EmmyLua support.

How to use?

--load 3DreamEngine
local dream = require("3DreamEngine")

--optionally set settings
dream:setBloom(3)

--init (applies settings)
dream:init()

--loads a object
local yourObject = dream:loadObject("examples/monkey/object")

--creates a light
local light = dream:newLight("point", dream.vec3(3, 2, 1), dream.vec3(1.0, 0.75, 0.2), 50.0)

--add shadow to light source
light:addNewShadow()

function love.draw()
    --prepare for rendering
    dream:prepare()

    --add light
    dream:addLight(light)

    --rotate, offset and draw
    yourObject:resetTransform()
    yourObject:rotateY(love.timer.getTime())
    yourObject:translate(0, 0, -3)
    dream:draw(yourObject)

    --render
    dream:present()
end

function love.update()
    --update resource loader
    dream:update()
end
