Example

--Create a window
window = Window:Create()
context = Context:Create(window)
world = World:Create()

camera = Camera:Create()
camera:SetRotation(35,0,0)
camera:Move(0,0,-6)

camera2 = Camera:Create()
camera2:Move(0,0,-4)
camera2:SetClearColor(1,0,0)
pivot = Pivot:Create()
camera2:SetParent(pivot)

local tex = Texture:Create(512,512)
local mtl = Material:Create()
mtl:SetShader("Shaders/Model/Diffuse.shader")
mtl:SetTexture(tex)
camera2:SetRenderTarget(tex)

local light = DirectionalLight:Create() 
light:SetRotation(35,35,0) 

local model = NULL 

model = Model:Box() 
model:SetPosition(-2,0,0) 
model:SetMaterial(mtl)

model = Model:Cylinder() 
model:SetColor(0.0,1.0,0.0) 
model:SetPosition(0,0,0) 

model = Model:Cone() 
model:SetColor(0.0,0.0,1.0) 
model:SetPosition(2,0,0) 

while true do
    
        pivot:Turn(0,0.5,0)
        
        if window:Closed() or window:KeyHit(Key.Escape) then return false end

        Time:Update()
        world:Update()
        world:Render()
        context:Sync()
end
