The objects presented here are sample 3D L-system objects generated 
via a PC program called LPARSER. It is included here to allow the user
to experiment and create their own original works of art.

This is a list of the object files which were originally created in 
DXF format by the LPARSER program and re-formated to Lightwave 3D
object format by the DXF2LW program.

These samples were created from the original .LS files which are L-system
commands to the LPARSER program to create an object via the following 
coammands in a batch file:

    del output.*
    del %1.dxf
    lparser -s2000 -3 %1
    rename output.dxf %1.dxf
    dxf2lw %1.dxf

For further information on the operation of the DXF2LW program see the 
README.txt file or for inforamtion on the operation of the LPARSER 
program see the LPARSER.TXT file which accompanies the LPARSER program.

After loading an object into LW, you may want to make a few adjustments.
Double sided is turned on by default and you may want to turn that off.
If you do make sure all the polygons are aligned (or flipped) in the
proper direction. Also the colors (surfaces) may need to be changed,
especially for the plants, trees, etc. The default color scheme is
carried over by my conversion program from the DXF object. (For plants,
trees, leaves, it works best to change the yellow to brown and all 
other colors which are in use to a shade of green (except for certain
"flower" objects which do need colors other than green). This might save
you the time of rendering to see what colors are attached to what
polygons.)

The LW manual (in the Appendix) for TIO conversion of DXF to LW format 
lists those colors. (TIO will convert the LPARSER DXF object but you 
might like the DXF2LW conversion program better to save some time. The 
TIO defaults are a bit different than the defaults that the DXF2LW 
program uses.) 

The DXF2LW program changes the axis on which the object is aligned. It 
flips the Y and Z point coordinates so the object will be oriented
along the Y axis instead of the Z axis. 

Anyhow, the source is included and if you have a C compiler, perhaps you
can improve on the code or just change the defaults to what suits you.
