I've been pounding on ldglite and I think I've gotten the effect I was
thinking of. I have a screenshot here (warning: 1024x768x32 PNG ahead):
http://www.sproat.us/l3glite-sketch.png
Changes I made:
- line types 3 and 4 render in white
- color 24 renders same color as 16 (to make up for loss of color)
Plus:
- a quickie type-2 and type-5 jitter for a sketchy look :-, (ok, this
wasn't what I was aiming for, but I think it'd be a cool option in addition
to the first two)
All changes so far were in L3View.cpp, mostly a couple new functions and
minor changes to DrawPart() (presumably if this were to make it into the
official version changes would have to happen to the parameters handler).
Just curious -- I saw code similar to DrawPart() in the function
Draw1PartPtr(), but I never reach this code when I run ldglite. Is this
still live code, and what is it used for? I'm guessing any changes I make
to DrawPart() would also need to be reflected in Draw1PartPtr().
Cheers,
