Polyhedron

Client Server

A polyhedron is built from half-spaces. Each half-space is defined by a plane (a point + a normal) and represents “everything on one side of that plane.”

function self:examplePolyhedron(pos)
    local dirs = {
        Vec3( 1, 0, 0),
        Vec3(-1, 0, 0),
        Vec3( 0, 1, 0),
        Vec3( 0, 0, 1)
    }

    local sides = {}
    for _, n in ipairs(dirs) do
        local pl = Vec4()
        pl:MakePlane(pos + n, n)
        table.insert(sides, pl)
    end

    local sh = Polyhedron()
    sh.sides = sides
    return sh
end
