[Bf-blender-npr] Feature/improvement idea for Freestyle

[Terry Hancock]

Hi all,

I was just looking at a Freestyle animation which had a problem I've 
encountered myself. Sometimes you need to have a crease or contour line, but 
as the camera angle changes, it will just disappear.

Apart from whether it looks better with or without the line, the sudden 
vanishing or appearance creates a distraction in the animation flow. It'd be 
nice to have a way to make such changes more gradual.

One way would be to fuzzify the rules for the edge classification -- with the 
"crease" line, I suppose this means turning the "crease angle" value into a 
range.

But, as the 'suggestive contour' is supposed to be "close" to a contour line, 
it would make sense if one could specify "how close", and again have that be 
"fuzzy".

The fuzziness could then be input for a line style modifier --- and then you 
could use it to allow an alpha-fadeout or a thinning of the line, rather than 
having it suddenly disappear.

Cheers,
Terry
