Due to popular request and usability considerations, this commit
reintroduces functionality similar to 2.4's "Draw Mode" for Grease
Pencil.
In the toolbar under the Draw/Line/Eraser buttons, you can find the
"Use Sketching Sessions" toggle, which enables this feature. This is a
per-scene setting, and defaults to off, so that the current 2.5
behaviour is still the default (i.e. the Grease Pencil operator will
only do a single stroke at a time).
With this option enabled, drawing with Grease Pencil will enter a
semi-modal state where you can draw multiple strokes without needing
to keep holding the DKEY throughout (though you'll still need to do so
to start the strokes, unless you use some toolbar buttons), while
still being able to manipulate the viewport. Header help-text prints
show the appropriate keybindings (i.e. press ESCKEY or ENTER to end
the sketching session).
Notes:
- To aid maintainability of the 3D-View toolbar code, I've taken the
liberty to factor out the groups of widgets which commonly occur in
most of the toolbars into separate functions (namely "Repeat" and
"Grease Pencil"). Perhaps it might make it slightly harder to newbies
to the toolbar code to grasp, though the physics panels are far worse
;)
- I've reshuffled some code in the Grease Pencil code to separate out
the various states of operation again more clearly, though some more
work is still needed there (TODO)
- There can now be only one Grease Pencil operator running at a time
- Redoing Grease Pencil operations where sketching sessions was
enabled still needs work. Namely, a way of delimiting the set of
points recorded into strokes is still needed (TODO)
- Ultimately, it should be possible to switch tools midway through a
session. Currently sessions are limited to only being able to be used
with a single drawing mode (TODO)
- After ending a drawing session, the titlebar contols may not work on
Windows without manually making the main window lose focus and then
regain (i.e. click on some other window in toolbar, then come back).
This may be related to (bug #25480)
Experimental tweak for the "Object Constraints" tab so that it now
shows a warning message instead of the "Add Constraints" button when
the active object is in Pose Mode. Hopefully this will further
alleviate any confusion over Object vs Bone level constraints.
Todo:
While coding this, I noticed that we currently don't have any way of
making help-text labels in UI panels which can span multiple lines
(word-wrapped or manually split). Probably not a critical issue, but
it would be nice for completeness...
* 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.
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...
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.
* 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.
* New option to "Regrow hair" for each frame.
* This was perhaps more a feature request, but there was a similar useful feature called "animated hair" in particles at some point.
* The previous behavior for hair growing was inconsistent to say the least, so this is a nice option to have.
graph editor:
- option "extend mode" requires channel-selection. Moved pulldown menu
from Key to Channel instead
- hotkey SHIFT+E for same operation now works both in channel list as in
main view.
* Textures applied to halo materials showed influence option for normal particles. This was really confusing, and with the cleanup I revealed a couple of hidden features too!
** Particles actually allow for textures to change halo size and hardness, but my guess is that nobody knew since the names were wrong in the ui!
** I also added the option to change the "add" value with a texture, since it was just silly not to have it.
* Halo material properties are also a bit cleaner now.
- This is working correctly but confusing, made more confusing by UI problems, corrected these and updated tooltop for 'tex.use_rgb_to_intensity'
- bad RNA arguments used for lamps (left over from RNA renaming).
- use isinstance(...), rather then comparing type() directly, this failed with lamp type checks.
- removed redundant argument to internal texture UI function factor_but().
- the texture color was drawn inactive when it was used in some cases.
Note. AFAIK its not possible to do a general check to see if a texture is colored or not, eg: its possible a plugin texture returns color in some cases and greyscale in others.
so for now always have color button active.
- Part of this report is a misunderstanding, but there was no access to bold/italic fonts.
- Added rna access and changed the operators to use only rna properties.
