Feature Request: Color coded direction (2D color space: aligned to viewing angle or the perpendicular plane)

Hi Marwan,

Thanks again for completing my other feature request for color-coding 3D direction as XYZ alignment -> RGB color sphere...

Will you please add a similar feature:

I would like again for the colors to represent alignment, but I would like a 2 Dimensional colormap, where one end of the spectrum represents alignment to the viewing angle of the camera, while the other end represents alignment to the plane perpendicular to that axis.

This feature would be nice because it will reduce the number of colors needed to deliver the information, and will still encode the most important directional information (direction in the image plane can be seen without the aid of color-coding).

If it is too hard to change color dynamically to the viewing angle, then we could allow the user to input the (3D spherical) angles, or choose an axis (e.g. Z axis)?

Thank you,
Sam

Start by locating the existing 3D direction-to-RGB color-coding feature referenced in the issue. Define whether the new 2D colormap follows the camera viewing angle dynamically or uses user-supplied spherical angles or an axis, then verify that the completed feature represents alignment with the selected viewing direction and perpendicular plane.
