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

Edit: Updated initial code to reflect the changes so far.

My other tought to fix it was when "pitch >= math.pi / 2" or "pitch <= math.pi / 2" then rotate the model instead of changing the camera's location, i had no time to test it yet tho.
