Usage: col_util [options]
various plots of maps, colors and blendings
Options
-h,--help this help message (run 'off_util -H help' for general help)
--version version information
-o <file> write output to file (default: write to standard output)
-f <type> for output type 4, map is output instead of OFF file
map type: rgb=1, antiprism=2, decimal=3 (default: 1)
Scene Options
-M <mode> color system mode. HSV=1, HSL=2, RGB=3 (default: 3)
plot as cone, bicone or cube respectively
-d <int> output type. plot=1, wheel=2, grid=3, map=4 (default: 1)
if color wheel and RGB, only one color blend is possible
-V verbose output. show color blend RGBA components
Output type 1 options
-r <int> HSV/HSL chroma 0 - none (cylinder), 1 - conic, 2 - hexagonal
-S HSV/HSL distribute colors heptagonally, 7 ways, as in the rainbow
-k <int> container control (default: 2)
0 - suppress, 1 - no facets on chroma-2, 2 - full
-z <int> 1 - show model upright, 2 - upright but don't rotate RGB cube
-q <int> height of the HSL cones (default: no change)
1 - double, 2 - make 90 degree dihedral
-p plot color centroid(s)
Color Blending Options
-s <sat> HSV/HSL saturation curve. Greather than 0 (default: 1)
1.0 - no curve. lower than 1.0 makes blends more pastel
4 numbers can be entered seperated by commas
-t <val> HSV/HSL threshold to use average saturation (default: 1)
between 0.0 (all averaging) and 1.0 (no averaging)
-v <val> HSV/HSL value curve (default: 0)
simulates subtractive coloring for blending 3 or more colors
RGB: Red+Green+Blue = White Cyan+Magenta+Yellow = Black
RYB: Red+Yellow+Blue = Black Green+Magenta+Orange = White
1.0 - no curve. lower than 1.0 number makes blends lighter
0.0 - use average value instead
4 numbers can be entered seperated by commas
-u <val> HSV/HSL value advance. Rotates meaning of blend to white and black
valid values 0.0 to 120.0 degrees (default: 0)
-a <int> alpha for blend. average=1, minimum=2, maximum=3 (default: 3)
-y RYB mode. Blend colors as in Red-Yellow-Blue color wheel
-c CMY mode. Complementary colors. RGB->(RYB/GMO)->CMY->blend
-b <val> All color sytem modes. brightness adjustment for final blend
valid values -1.0 to +1.0 (default: 0)
negative for darker, positive for lighter, 0 for no change
Coloring Options (run 'off_util -H color' for help on color formats)
-m <map> get colors from a color map, or multiple maps seperated by commas
-O <file> get colors from an OFF file
note: -m and -O may be used together
-U allow only unique colors (sorts by color)
-Z <int> maximum entries to read from open ended maps (default: 256)
