* Massive reorganization of pointcache code, things are now cleaner than ever.
* For all but smoke the cache is first written to memory when using disk cache and after that written to disk in one operation. This allows less disk operations and the possibility to compress the data before writing it to disk.
* Previously only smoke cache could be compressed, now the same options exist for other physics types too (when using disk cache). For now the default compression option is still "no compression", but if there aren't any problems this can be set to "light compression" as it's actually faster than no compression in most cases since there's less data to write to the disk. Based on quick tests heavy compression can reduce the file size down to 1/3rd of the original size, but is really slow compared to other options, so it should be used only if file size is critical!
* The pointcache code wasn't really 64bit compatible (for disk cache) until now, so this update should fix some crashes on 64bit builds too. Now all integer data that's saved to disk uses 32 bit unsigned integers, so simulations done on 64bit should load fine on 32bit machines and vice versa. (Important disk cache simulations made on 64bit builds should be converted to memory cache in a revision before this commit).
* There are also the beginnings of extradata handling code in pointcache in anticipation of adding the dynamic springs for particle fluids (the springs need to be stored as extradata into point cache).
* Particles were being read from the cache with a slightly wrong framerate. In most cases this probably wasn't noticeable, but none the less the code is now correct in every way.
* Small other fixes here and there & some cosmetic changes to cache panel, but over all there should be no functional changes other than the new disk cache compression options.
* This whole re-organization also seems to fix bug #25436 and hopefully shouldn't introduce any new ones!
- the invert flag was only being used for multi-modifier, but there is no reason not to use this in normal cases as well.
- Armature modifier RNA name 'vertex_group' was incorrectly named 'vertex_group_multi_modifier' (own fault), confusion was caused by 'invert_vertex_group_multi_modifier' which was correct.
"Numpad 1" shortcut to set preview view zoom to 1:1 (i.e. 100%) did
not exist in View menu. While investigating this, I found that the
operator was missing a description/tooltip, so added one too.
- rather then use unlink="None", just don't pass unlink as a keyword. This is more pythonic.
- added an RNA flag for properties which cant be unlinked by setting to None.
Bugfix for job cancellation (reported by Carsten in email)
Ended up recoding part of the communication pipe (use json more consistently)
Fix bpy data modifications where it shouldn't happen (as a bonus, thumbnailing is now done out of process)
Reshuffling order of "sync" and "Auto-Keying" buttons so that they are
grouped more appropriately. Hopefully this isn't too much of a muscle-
memory breaker...
adjust dependency calculations for cache files of smoke simulations (no more separate paths for low and high). That was changed a while ago in the api, just didn't update yet.
Normal Map bool and the normal_space menu are only used for material based textures, not for textures used by lamp/world etc. Accidentally ported this over from 2.49, where these buttons are drawn even they don't work in that context.
Property buttons: the "ID template" allowed to unlink data from object,
like Mesh or Curve etc, which is not supported. Button now is hidden.
Thanks Dan Eicher for patch.
Also: improved tooltip for 'data browse'. It was generic, now it gives
specific per-type information.
- operators need to enable the option OPTYPE_PRESET or 'PRESET' in python.
- hidden properties are not written.
- currently this only works in the file selector (enabled for FBX/OBJ export)
- currently the menu label doesnt change when presets are selected, this is a TODO, not so simple since the UI is defined in C and the label in python.
- presets save in "scripts/presets/operators/*id*/*.py"
- adding template of a add_object addon from Florian Meyer (testscreenings)
- this template is using the new add_utils module in bf-extensions (also from Florian)
- SSS Presets were not working on pinned materials.
- added ability for save-presets to define variables to stop them becoming too verbose.
- remove object.active_node_material
[#25284] Traceback error on "System Info" script
- Align was only working on mesh objects, now operate on all objects, missing boundbox's are treated as single points.
- obj.bound_box was returning all nan's for object types with no boundbox.
- ENUM_FLAG type enums were showing no text when displayed in operator redo panel.
it (eg cameras)
When trying to add a modifier to non-geometry objects, warnings are
now shown instead of just adding some (useless) modifiers that cannot
be removed later.
* Pointcache code was quite ugly looking and complicated, so here are mostly just cosmetic adjustments, but some improved logic also.
* Slight cleanup of pointcache ui too.
* Shouldn't have any functional changes what so ever, so poke me right away if something seems off.
was actually incorrect location for everything!
- x3d's global scene rotation value wasnt converted from deg to radians.
- camera viewport was also incorrectly exported.
use mathutils rather then inline math for rotations.
