Sure, just change the OnUpdate function to this:

local function OnUpdate(self)
    local x, y = GetCursorPosition()
    local yaw = self.yaw + (x - self.x) * INCREMENT_RATIO
    local pitch = self.pitch + (y - self.y) * INCREMENT_RATIO
    if pitch > HALF_PI then
        pitch = HALF_PI
    elseif pitch < -HALF_PI then
        pitch = -HALF_PI
    end
    self:SetOrientation(self.distance, yaw, pitch)
    self.x, self.y = x, y
end

Maybe later. I only played around with this to get a break from my current project which I need to get back to.
