I've made a new function for LDS called PIPE. It's an extension of the LINE function.
Remember:?
LINE
POINT x y z
POINT x y z
...
POINT x y z
LINE END
Now, PIPE works the same way but with that difference it's in 3D:
PIPE [n_sectors total_sectors] [color]
SEGMENT x y z a b c d e f g h i
SEGMENT x y z a b c d e f g h i
...
SEGMENT x y z a b c d e f g h i
PIPE END
The parameters "x y z a b c d e f g h i" are the same as a pretended n-nEDGE have.
With just two segments, I'm able to make any partial or whole cone. With multiple segments, I can bend and shape a hose
or bransch or anything. (Do I have to say I'm proud? :-) )
Now, I'm willing to create some META-commands for other programs to make primitive substitutions, like for example:
[IN.LDS]
pipe 4 16 blue
segm 0 0 0 0 0 0 100 0 0 0 0 100
segm 200 0 0 0 0 0 50 0 0 0 0 50
pipe end
makes...
[OUT.DAT]
0 IFDEF PIPE
0 PIPE 4 16 1

0 SEGMENT 200 0 0 0 0 0 50 0 0 0 0 50
0 PIPE END

5 24 0 38.27 92.39 200 19.135 46.195 0 70.71 70.71 0 0 100
4 1 0 38.27 92.39 200 19.135 46.195 200 0 50 0 0 100
0 END IF
(Yes, I know the optional lines get wrong colour).
Should I do that, or just output the pure LDraw code? Would anybody find it practical?
Would there be a more proper syntax?
