[Bf-committers] In need for help/documentation for modifiers

Im currently looking into the sources of blender and try to understand 
how the modifiers are working. Writing a modifier seams to be simple, 
but on the other side there are many other files that are keeping lists 
of them (to know which are available). This is somehow like finding all 
needles in a haystack.

Is there a documentation on modifiers, that lists all the files that 
need to be changed if you write/add your own modifier? Need this files 
to be changed, or will they be updated automatically? (guess not)

Somehow i miss some document that points out how i can write my own 
modifier from scratch (including gui etc.). At least a very simple 
example would be nice.

Currently i developed code to write a so called RestoreVolume-Modifer, 
that ensures that a closed mesh keeps/restores it's original volume 
after deformations (due to other modifiers). Simplest example would be a 
muscle that contracts and will grow on the sides (controllable by vertex 
group), because of the loss of volume in length.

Any suggestions or hints?

Best wishes Tobias Oelgarte
