CountTriangles
This function gets the number of triangles in a surface.
Syntax
Returns
Returns the number of triangles in a surface, which is equal to the number of indices divided by three.
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 treu do
if window:Closed() or window:KeyHit(Key.Escape) then return false end
Time:Update()
world:Update()
world:Render()
context:Sync()
end
