Hello everybody,


It seems to me that someone posted a method of converting hsv to rgb 
using only functions.



I can't find it or I've had a dream ?

Thank you for your memories ;)

colors.inc:

// Converts a color in HSV color space to a color in RGB color space.
// Input:  < Hue, Saturation, Value, Filter, Transmit >
// Output: < Red, Green, Blue, Filter, Transmit >
#macro CHSV2RGB(Color)
    #local HSVFT = color Color;
    #local H = (HSVFT.red);
    #local S = (HSVFT.green);
    #local V = (HSVFT.blue);
    #local SatRGB = CH2RGB(H);
    #local RGB = ( ((1-S)*<1,1,1> + S*SatRGB) * V );
    <RGB.red,RGB.green,RGB.blue,(HSVFT.filter),(HSVFT.transmit)>
#end


Best regards
