Update

This function updates a surface after it has been modified. This will update the binormals and tangents, update the AABB, and create a new shape for picking.

Syntax

Update(bool force=false)

Parameters

force: if set to true everything will be updated, otherwise only required updates will be made.

Example

--Create a window
window = Window:Create()
context = Context:Create(window)
world = World:Create() 
local camera = Camera:Create() 
camera:SetRotation(35,0,0) 
camera:Move(0,0,-3) 
local light = DirectionalLight:Create() 
light:SetRotation(35,35,0) 
        
local model = Model:Create() 
model:SetColor(1.0,0.0,1.0) 
        
local surface = model:AddSurface()
surface:AddVertex(-0.5,-0.5,0, 0,0,-1) 
surface:AddVertex(0.5,-0.5,0, 0,0,-1) 
surface:AddVertex(0.5,0.5,0, 0,0,-1) 
surface:AddVertex(-0.5,0.5,0, 0,0,-1) 
surface:AddTriangle(2,1,0) 
surface:AddTriangle(0,3,2) 
surface:Update() 
model:UpdateAABB(Entity.LocalAABB)
model:UpdateAABB(Entity.GlobalAABB) 

while true do        
        if window:Closed() or window:KeyHit(Key.Escape) then return false end

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