   Render a HSV Colorpicker
  Hi,i'm wondering if there are clever ways to render a HSV Colorpicker. It's easy to get an RGB Colorpicker to work since all values are linear and work with the same values the fixed function pipeline does. But! I'm inside a scripting engine that doesn't reveal much of OpenGL, especially no shader things that would help me find some ways to render as RGB and interpret it as HSV or similar in the fragment shader.I was wondering if it's still possible to use fixed function pipeline functionality to acchief an accurate HSV Colorpicker. This runs inside a 3d Game, Tribes1 to be exact and i cannot affort to render each pixel by itself. (which would be theretically possible)I was wondering if i missed some facts of the HSV model that would allow me to use the rgb interpolation to acchief my goal by specifying just a few vertices.Also, as a discussion point: HSV would be neat to have in the OpenGL Spec, i mean most effects just vary in 1 variable of the HSV model, but in 3 of RGB.
