Also use const char in many other parts of blenders code.
Currently this gives warnings for setting operator id, label and description since these are an exception and allocated beforehand.
Fix#22051: crash when scaling parent metaball. Keep the constant resolution
for any motherball's scale.
This avoids running out of memory when scaling the metaball down, but there's
a reason it depends on this scaling, for example for instancing it's more
useful to have this. It also doesn't really solve the problem but only moves it,
it's still possible to run out of memory with different setups/scales.
Fix#21187: 2.5svn26947 - particles + meta sphere = crash in rendering
Use separated displists for mballs in view3d and render stuff.
Do not recalculate displist for view3d while rendering - mball.c
uses several global variables which shouldn't be accepted from
parallel threads.
* Added callback function for some metaball properties:
When some properties (wiresize, threshold, update flags) of metaball are changed, then these properties are copied to all metaballs in the group (all metaballs with same base name). This is important to "share" some properties between metaballs, because polygonisation of metaball is influenced only by properties of base metaball and base metaball can be changed.
* Improved drawing of selected Metaball objects
Think global, act local!
The old favorite G.scene gone! Man... that took almost 2 days.
Also removed G.curscreen and G.edbo.
Not everything could get solved; here's some notes.
- modifiers now store current scene in ModifierData. This is not
meant for permanent, but it can probably stick there until we
cleaned the anim system and depsgraph to cope better with
timing issues.
- Game engine G.scene should become an argument for staring it.
Didn't solve this yet.
- Texture nodes should get scene cfra, but the current implementation
is too tightly wrapped to do it easily.
polygonization of 512 MetaBalls:
- version 2.33a: 76 s
- current cvs version 8 s
- button "Never" is added in button window: Metaballs are polygonized only during render time (it is useful for particle animation) http://e-learning.vslib.cz/hnidek/misc/bowl_metaballs.blend
even for each redraw! Now its all smooth & fast again.
introduced new kernel API call: int is_basis_mball(ob), this provides a
quick check of the object is the actual basis for the displaylist and
polygonization.
(adding)
#ifdef HAVE_CONFIG_H
#include <config.h>
#endif
also the Makefile.in's were from previous patch adding
the system depend stuff to configure.ac
