Syntax

number GetTriangleVertex(number t, number c)

Parameters

a: the index of the triangle to return the vertex of.
v: the corner of the triangle to return the vertex of. This value may be 0, 1, or 2.

Returns

Returns the vertex index of the specified triangle corner.

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:Box() 
model:SetColor(0.0,0.0,1.0) 
local surface = model:GetSurface(0) 

--Print out the triangle indices
for t=0,surface:CountTriangles()-1 do
       
        System:Print(surface:GetTriangleVertex(t,0)..", "..surface:GetTriangleVertex(t,1)..", "..surface:GetTriangleVertex(t,2)) 
end
        
while true do

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

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