RGB to HSV is a utility node that allows you to
convert an RGB (Red-Green-Blue) color into an
HSV (Hue-Saturation-Value) color.
There are some kinds of effects that are easier to calculate
using HSV values than RGB values. With this node, you can
convert the output of any shading network into HSV values.
Example: Say you want to 'rotate' the Hue values of an
image, like when you adjust the Hue control on a color television.
This shifts the colors in the image around; red becomes yellow,
green becomes cyan, etc. You could do that like this:
File Texture RGBtoHSV PlusMinusAverage HSVtoRGB Blinn
------------ -------- ---------------- -------- -----
Out Color------>In Rgb
Out Hsv---->Input3D[0]
Input3D[1]=(60,0,0)
Operation = "Sum"
Output3D------------->In Hsv
Out Rgb--->Color
