Shapes can exhibit different colors. And just like the other transformations, adding color to a shape produces a new shape, one with color.
NOTE: 2D shapes cannot exhibit colors today. This is a known issue.
let a = color("Red",sphere()) let b = color([1, 0.5, 0.3],sphere()) let c = color([1, 0.5, 0.3, 0.6],sphere(10),cube(20))
See the Extended Color Keywords for all available colors. Color keywords are case-insensitive, e.g. 'RED' is the same as 'red'.
The CSG library functions can also be used. NOTE: Deprecated in the V2 API
let a = object.setColor(css2rgb('dodgerblue')) let b = sphere().setColor(1, 0.5, 0.3) let c = sphere().setColor([1, 0.5,0.3, 0.7])
Note: There are some Transparency_Sorting|OpenGL Transparency Limitations, e.g. and depending on the order of colors, you might not see through otherwise partially transparent objects.
Following functions to convert between color spaces.
let rgb = css2rgb('navy') let rgb = html2rgb('#RRGGBB') let rgb = hsl2rgb(h,s,l) // or hsl2rgb([h,s,l]) let rgb = hsv2rgb(h,s,v) // or hsv2rgb([h,s,v]) let hsv = rgb2hsv(r,g,b) // or rgb2hsv([r,g,b]) let hsl = rgb2hsl(r,g,b) // or rgb2hsl([r,g,b]) let html = rgb2html(r,g,b)
