development

Due to rapid changes to 3Dream I am working on a seperate branch ("beta"). While this branch is faster and offers more and improved features, I am experimenting with it and may change how things work.

documentation

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

How to use?

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

--optionally set settings
dream:setBloom(3)

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

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

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

--add shadow
light:addShadow()

function love.draw()
  --reset lighting to default sun
  dream:resetLight()

  --add light
  dream:addLight(light)  
  
  --prepare for rendering
  dream:prepare()  

  --rotate, draw and offset
  yourObject:rotateY(love.timer.getDelta())
  dream:draw(yourObject, 0, 0, -5)

  --render
  dream:present()
end

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