I am a new to this list. I have been building things with OpenScad and
have written some useful functions and modules that are important to
me at least and might be important to others. In particular the
following:

ROTATION MODULES

Rotate about a vector through the origin. (clockwise looking
towards origin)
Rotate about a line defined by two points. (clockwise looking from
second point to first.)

MIRROR MODULE
2. Mirror about a plane defined by two point. (plane is orthogonal
to linesegment passing through first point.)

The library also contains extensive support for affine transforms
including a true affine inverse that supports the above and future work.
If a shape is distorted by an affine transform, the inverse transform
will restore the shape.

Questions:

Is anyone interested?
Should I post current source here or somewhere else?
Where are changes to underlying openscad code discussed?
I have extensive programming and math experience and would like to
participate.

Thanks
Otto

It's always useful to look at code written by someone
else, there's a good chance learning something.

Should I post current source here or somewhere else?

If you have some short snippets that might be generally
useful (and you are ok with releasing those to public
domain / CC0), you could add those to:

https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/Tips_and_Tricks

For anything bigger, a github repo seems to be a good
place, or something like Thingiverse or YouMagine might
be an option, although those are not really ideal for
sharing code libraries.

Where are changes to underlying openscad code discussed?

Mainly IRC (freenode/#openscad) and/or github.
Sometimes also here in the forum, but that gets awkward
quite soon with copying files around.

I have extensive programming and math experience and
would like to participate.

That would be awesome :).

ciao,
Torsten.

Should we open discussions re MCAD https://github.com/openscad/MCAD
again?
