I can only comment on this one, the posting below from someone else. >From the Documentation Centre on Opacity: Opacity Opacity[a] is a graphics directive which specifies that graphical objects which follow are to be displayed, if possible, with opacity a. Opacity[a, color] uses the specified color with opacity a. MORE INFORMATION * Opacity runs from 0 to 1, with 0 representing perfect transparency. * If an opacity a object with color c1 is placed in front of an object with color c2, the resulting color will be the blend ac1+(1-a) c2. * If red and blue with opacity 0.5 are combined, the result is purple=97not black, as it would be with physical monochromatic filters. =BB * Opacity works in both 2D and 3D graphics. * It may take significantly longer to render 3D graphics that involve transparent surfaces. * Graphics that involve transparency may need to be printed as high-resolution bitmaps. So, this last one is what I meant. And, from my experience, is true. Cheers, t.
