Shapes can exhibit different colors. And just like the other transformations, adding color to a shape produces a new shape, i.e. one with color.
Colors are not only important for visual rendering but also controlling the selection of filaments during 3D printing. Therefore, colors should be applied as the last step in designs to insure proper printing.
const myshape = colorize([1, 0, 0], sphere()) // RGB red const myshape = colorize([1, 0.5, 0.3], sphere()) // color const myshape = colorize([1, 0.5, 0.3, 0.6], sphere()) // color plus alpha transparency
Note: There are known issues with transparency, and depending on the order of colors, objects may not seem transparent. Try different 'alpha' values or colors.
Color Space Conversion
There are several functions to convert between color spaces, including color names.
const wildcylinder = colorize(colorNameToRgb('fuchsia'), cylinder()) const bluesphere = colorize(hexToRgb('#000080'), sphere()) // navy blue const mysphere = colorize(hslToRgb([0.9166666666666666, 1, 0.5]), sphere()) const mysphere = colorize(hsvToRgb([0.9166666666666666, 1, 1]), sphere())
- r,g,b (red, green, blue) of RGB color model
- h,s,l (hue, saturation, lightness) of HSL color model
- h,s,v (hue, saturation, value) of HSV color model
See the Extended Color Keywords for all available colors. Color keywords are case-insensitive, e.g. 'RED' is the same as 'red'.
