I didn't add any flags, I still haven't taken the time to learn that part of
the code yet. However, the only changes were to L3View.cpp, and are very
straightforward. Note that this is just a proof-of-concept, and is far from
being ready for inclusion into ldglite!
Here's my copy (warning, DOS line endings and no new comments):
http://www.sproat.us/L3View.cpp
What I did:
- new global constant jitter_max -- this multiplied by the length of the
line segment determines the maximum jitter for a given line endpoint (still
need to implement scaling for line type 5, see below)
- new global constant jitter_num -- this is the number of jittered lines to
draw in addition to the unperterbed line; a value of 0 means no jittered lines
- new introduced function jitter() -- returns a random floating-point value
which lies between the low and high parameters
- new function render_line_jitter() -- draws one unperterbed line and
jitter_num perterbed lines
- new function render_five_jitter() -- draws one unperterbed type-5 line
and jitter_num perterbed type-5 lines (no scaling, but I think I should
scale by the distance between first two points; I don't know if I should
jitter the last two points or not...!)
- modified function DrawPart() -- color 24 is replaced with CurColor
instead of edge_color(); switch(LinePtr->LineType) cases 3 and 4 now call
render_line_jitter() and render_line_jitter() and render_five_jitter(),
respectively (previously called render_line(), render_line(), and
render_five() )
Hmm. This is why I should write comments... :-,
Cheers,
