Hi Kevin,

It seems you forgot to link in CC3250.DLL... doesn't work on my system.

Boy, were you right, the triangle synthesis took a 3K file and made a 2M
file.  Unpalatable.

I switched lsynth over to use LDRAW parts for synthesis.  Now that 3K file
ends up to be 500K, still much larger, but certainly better than before.

That's the kind of size I got... We must keep in mind that even if the ldraw
file is smaller using parts, the number of triangle to render will be the
same or even higher :c(

The use of ldraw parts has an added benefit: it is more compatible with
LeoCad (with triangles you would have to create a new part and import it in
Leocad to be able to display something)

I've got most of the algorithms for rubber bands with pulleys/pins inside or
outside the bands as well as bands that have crossed over on themselves.  I
have not wandered through non-planar arrangements though.


I began to code crossed bands in my rubberbelt generator, but other project
kept me from finishing that. Note that crossed bands are not planar, there
is the thickness of the band to consider !

Cheers,

Philo

Hi Philo, (...) Oop.s I reworked the organization of the code and ended up messing this up. 1.0.0.2 is uploaded now. (...) I understand, but I'm not sure what can be done about this. I used the cross sectional parts that already existed for flexible (...) (22 years ago, 6-Oct-02, to lugnet.cad.dev)

Hi Philo, I finally got my tangent between two circles code working! I can have two or more pulleys (or pins), with them inside or outside the rubber band, and band crossings. Right now they all have to be in the XY plane. I'm working on the code to (...) (22 years ago, 9-Oct-02, to lugnet.cad.dev)
