Fixel overlay: Control fixel thickness #439

Open Lestropie opened 8 years ago

Lestropie commented 8 years ago

Just saw this in an article: They use fixed fixel lengths, but the thickness (of genuine cylinders in their case) denotes the partial volume. Might be useful...?

What article? I'll take a look. While better than fixel length, I still think width will suffer from under-representation when visualising fixels pointing out of the image plane. For this reason I still think visualising quantitative information with colour maps is best.

Not suggesting to use width or length to look at precise quantitative values instead of colour; just to give a vague sense of 'major' vs. 'minor' fixels, when you're also looking at some quantitative value other than size using a colour map at the time. Gives a bit of 'anti-aliasing' in a way.
