This function sets the maximum vertex displacement distance.

Syntax

• SetDisplacement(number displacement, number offset = 0)

Example

local remotepath = "https://raw.githubusercontent.com/UltraEngine/Documentation/master/Assets"

--Get the primary display
local displays = GetDisplays()

--Create a window
local window = CreateWindow("Ultra Engine", 0, 0, 1280, 720, displays[1], WINDOW_CENTER | WINDOW_TITLEBAR)

--Create a rendering framebuffer
local framebuffer = CreateFramebuffer(window)

--Create a world
local world = CreateWorld()
world:SetAmbientLight(0)

--Create a camera
local camera = CreateCamera(world)
camera:SetPosition(0, 0, -1)
camera:SetFov(70)
camera:SetClearColor(0.125)
camera:SetTessellation(4)

--Create a light
local light = CreateBoxLight(world)
light:SetRange(-10, 10)
light:SetRotation(35, 35, 0)
light:SetColor(4)

--Display material
local model = CreateCubeSphere(world, 0.5, 8, MESH_QUADS)
local mtl = LoadMaterial(remotepath .. "/Materials/Ground/rocks_ground_02.json")
mtl:SetDisplacement(0.075)
model:SetMaterial(mtl)

--Main loop
while window:Closed() == false and window:KeyHit(KEY_ESCAPE) == false do
    --Arrow keys move
    if window:KeyDown(KEY_DOWN) then camera:Move(0, 0, -0.01) end
    if window:KeyDown(KEY_UP) then camera:Move(0, 0, 0.01) end

    --Show wireframe render when key is pressed
    camera:SetWireframe(window:KeyDown(KEY_W))

    --Rotate the model
    model:Turn(0, 0.1, 0)

    world:Update()
    world:Render(framebuffer)
