Not sure if this is related to the error, but looks like your 3rd point is not initialized correctly:<div><span class="Apple-style-span" style="border-collapse: collapse; font-family: Menlo; font-size: 11px; ">Point3[<span style="color: rgb(44, 46, 207); ">0</span>] = <span style="color: rgb(44, 46, 207); ">0</span>; Point2[<span style="color: rgb(44, 46, 207); ">1</span>] = -<span style="color: rgb(44, 46, 207); ">1</span>;</span><br>
