Hello, I found a devforum post about this already, but the poster made the voxel sphere solid. IS it at all possible to make this hollow so only the top layer is generated?
Post referenced: Sphere Generation
That’s my post!
The code there is pretty outdated so I made an updated version that allows you to change the thickness of the sphere.
Sphere Module
-- Sphere
-- Quoteory
-- August 8, 2019 [Updated October 4th, 2021]
local RunService = game:GetService("RunService")
local spherePart = Instance.new("Part")
spherePart.Anchored = true
spherePart.CastShadow = false
spherePart.Material = Enum.Material.Slate
local Sphere = {}
function Sphere:Create(radius, partSize, position, thickness)
radius = radius or 10
partSize = partSize or 5
position = position or Vector3.new(0, 0, 0)
thickness = thickness or radius
local sphere = Instance.new("Model")
sphere.Name = "Sphere"
local templateCube = spherePart:Clone()
templateCube.Size = Vector3.new(partSize, partSize, partSize)
local thicknessRadiusDifference = radius - thickness
for x = -radius, radius do
local powX = math.pow(x, 2)
for y = -radius, radius do
local powY = math.pow(y, 2)
for z = -radius, radius do
local powZ = math.pow(z, 2)
local radiusNum = math.sqrt(powX + powY + powZ)
local isInRadius = radiusNum > thicknessRadiusDifference and radiusNum <= radius
if isInRadius then
local cube = templateCube:Clone()
cube.Position = Vector3.new(x*partSize, y*partSize, z*partSize)
cube.Parent = sphere
end
end
end
RunService.Heartbeat:Wait()
end
sphere.Parent = workspace
sphere:MoveTo(position)
return sphere
end
return Sphere
Script
local Sphere = require(script.Sphere)
local sphere = Sphere:Create(
3, -- radius
20, -- part size
Vector3.new(-72, 41.5, -2), -- position
1 -- thickness (leave empty if you want the sphere to be completely filled)
)
