just did a few tests, with the 'surprising' result that balls are not curves ..
and i don't want to be swamped by bug reports tellling me
'it does not collide as i whised it would'
only alow self collision for suited objects
feature request from hairdressers
self collision for curves
works amazingly well if you keep in mind there balls around vertices colliding
ironing out a few glitches related to goal pinning
volatile test blend ->
http://www.wund.homepage.t-online.de/hidden/sb_col_must.blend
+ adding a few alternative collision ball calculation algos
since i did not want to blow up (waste) DNA space without need,
coded as -1.0 -0.1 -1.1 values in 'ball size' (look at tooltip popup)
added in place operations.
Vector_iadd vec1+=vec2
Vector_isub vec1-=vec2
Vector_imul vec1*=float or vec1*=mat
Vector_idiv vec1/=float
length is now writable vec.length= float
removed the need for casting python objects to Vectors pyobjects when performing vec/float arithmatic.
a PyObject for coercing has also been removed from the vector struct so a little less memory will be used also.
Benchmarked before and after this change

file was also happening on files made with current CVS (until next release).
Added a simple check to make it only happen on old files where there was no
radius before.
This patch adds the feature of IPO curve mirroring. It mirrors the selected keyframes in the active ipo curves over a user-nominated mirror-line.
Options are:
- Mirror over current frame
- Mirror over vertical axis (X = 0)
- Mirror over horizontal axis (Y = 0)
Functionality can be accessed from:
- Hotkey M in IPO editor
- Submenu in header of IPO editor
** This is a heavily modified version of the patch, but the idea is the same. **
This adds X and Y as hotkey for constraining IPO transforms (grab only) and also fixes the display to only show relevant information when constraining (grab and scale).
That is, a 3D curve now displays as ->->->-> instead of -|-|-|-|.
Comparing the two, I didn't find the arrow display any more confusing then the straight lines when dealing with loops and tilt variations. Sharp turns are more likely to display crossed lines though.
Others should feel free to disagree and make it better.
- added verse support
- verse library and server are compiled with the extern solution
- note: verse server still misses icon, VS2003 refuses to add the currently provided icon
simple (naive) self collision
estimates a collision ball
using the spring lenght to attached neighbours
(idea stolen from old cloth modifier files, but i'm sure ZAZ and genscher won't mind)
-- usefull for untangeling static cloth like objects
-- may be used for cloth simulation with known limitations
like 'tunnel effect' if objects are moving too fast ...
demo -- volatile files

Some operations like edge loop deselect would cause selection history
to become invalid. Added a sanity check to countall() to try and catch
these when they happen.
The wait cursor was being called during editmode enter and exit for meshes.
This was a problem for several reasons. First of all, python modules like
Mesh now make use of editmode features. These methods that wrap editmode
tools may be called many times during the execution of a script
and lead to the wait cursor rapidly flickering on and off.
The other problem was that the wait cursor wasn't being called for editmode
enter and exit of all data types. This is unified now.
-New Arguments
enter_editmode() should be passed a nonzero integer or simply EM_WAITCURSOR
if the wait cursor is desired. Currently only the python API passes a '0'
to enter_editmode()
exit_editmode() has several options and they are passed in as the bitflags
EM_FREEDATA, EM_FREEUNDO and EM_WAITCURSOR. These flags are defined in
BDR_editobject.h.
countall() wasn't being called when scenes were being added/deleted.
This caused the info header to temporarily display incorrect information
about scene statistics.
Added Mesh .key .removeAllKeys() and .insertKey() for MDD support (was using NMesh just for keys before)
Since this is aparently an experemental feature in NMesh we may want to change this.
Gives local structure stability for though fabrics, thin steelplates ..
even suzanne gets pretty crash resistant that way.
If non zero it not only adds diagonals but all other "2edge-wide" springs
so it somehow replaces stiff quads for meshes too.
- A new Save image function, next to the existing Save As.
- Shortcut keys Alt+S, Alt+R, Alt+O and Alt+N for Save, Reload, Open
and New image respectively, consistent with the text editor window.
- Hide Select and UVs menus when UV editing isn't active.
- Removed duplicate and unused code, also moved some functions.
