I have used the EditableMesh class in order to draw a plane with the given quantity of verticies.
Here is how the mesh looks like if all the verticies are on Y = 0
Here is the exact same mesh but the Y value is based on a math.noise function
Here is my code on making the mesh:
local function DrawGridMesh(mesh: EditableMesh, def: number, yFunction: (number, number)->(number))
local vertexMatrix = {}
for X = 1, def do
vertexMatrix[X] = {}
for Y = 1, def do
vertexMatrix[X][Y] = mesh:AddVertex(
Vector3.new(
(X-1)/(def-1) - 0.5,
yFunction(X, Y),
(Y-1)/(def-1) - 0.5
))
end
end
for X = 1, def - 1 do
for Y = 1, def - 1 do
mesh:AddTriangle(
vertexMatrix[X][Y],
vertexMatrix[X][Y+1],
vertexMatrix[X+1][Y+1]
)
mesh:AddTriangle(
vertexMatrix[X+1][Y+1],
vertexMatrix[X+1][Y],
vertexMatrix[X][Y]
)
end
end
return vertexMatrix
end
