Hi Reuben!
Thank you for hosting my program on your web space, for promoting my program to
other part authors and Thanks to J.C. Tchang for writing this great manual!
I am still working on the LPC.
Here is my TODO-List:
- To write a documentation or a manual
- To implement automatic primitive recognition and substitution (the program identifies capabilities of xxxdisc.dat and xxxndis.dat primitives and 48-primitive counterparts)
Status of implementation: Nearly finished, but it will take two weeks or more to
complete, because of the heavy mathematics in discrete geometry.
Example of this feature:
The method expects triangles like

3 16 0 0 0 0.3173471 0 -0.9483568 0.6561 0 -0.7547
and converts this input to only two lines
1 16 0 0 0 0.6561 0 0.7547 0 1 0 -0.7547 0 0.6561 4-4disc.dat
3 4 2 0 2 0.7547 0 0.6561 0.44617786 0 0.89499448
The algorithm is very complex to implement for ndis-primitives, but I will make
it. This feature is really nice to have.
- Auto-Rectifie the pattern while exporting the pattern as DAT (I have to ask Philo. He is the author of the program rectifier [http://www.philohome.com/isecalc/rectifier.htm] )
- Implement the CSG Add-function (http://en.wikipedia.org/wiki/Constructive_solid_geometry)
- Minor improvements on DAT- in- and export
- General bugfixing, code- and GUI-cleanup.
- Performance improvements
Thanks for your support

I'll translate it into English and German.
