Mouse Draw Spline Example:
Using the ScreenPosTo3d op we can convert the mouse coordinates to 3D coordinates. For this you need to disable the Flip Y port of the Mouse op.
Using the ArrayPushValue3X op we add the (converted) x and z coordinates (together with z=0) to the array and draw it with the SimpleSpline op.
