It would be very handy in many situations to have this kind of visual parameter.
You drag around the white pointer and the output is a vector3 value, whose X and Y components are the 2D direction in respect to the center, and Z component is the intensity (distance from the center).

Any chance to have it implemented in Houdini?


In the example the wheel parameter is outputting the following vector (0.6, 07, 0.8): or else a direction of (0.6, 0.7), with an intensity of 0.8
