In theory, actions can now be evaluated in NLA, though in practice, we don't have an NLA Editor to create data to use this yet! Next up, transitions...
Some notes:
* Recoded the way the 'accumulation' methods work (i.e. blend, add, etc.), adding a few new ones. It should now be more obvious how these work.
* Some assorted code cleanups done too (removing unneeded vars/args)
* Refactored F-Curve Modifier stack evaluation into functions which can be reused for F-Curve Modifiers on NLA-Strips
* Started setting up temporary accumulation buffer system for use when evaluating strips
* Buttons are now created first, and after that the layout is computed.
This means the layout engine now works at button level, and makes it
easier to write templates. Otherwise you had to store all info and
create the buttons later.
* Added interface_templates.c as a separate file to put templates in.
These can contain regular buttons, and can be put in a Free layout,
which means you can specify manual coordinates, but still get nested
correct inside other layouts.
* API was changed to allow better nesting. Previously items were added
in the last added layout specifier, i.e. one level up in the layout
hierarchy. This doesn't work well in always, so now when creating things
like rows or columns it always returns a layout which you have to add
the items in. All py scripts were updated to follow this.
* Computing the layout now goes in two passes, first estimating the
required width/height of all nested layouts, and then in the second
pass using the results of that to decide on the actual locations.
* Enum and array buttons now follow the direction of the layout, i.e.
they are vertical or horizontal depending if they are in a column or row.
* Color properties now get a color picker, and only get the additional
RGB sliders with Expand=True.
* File/directory string properties now get a button next to them for
opening the file browse, though this is not implemented yet.
* Layout items can now be aligned, set align=True when creating a column,
row, etc.
* Buttons now get a minimum width of one icon (avoids squashing icon
buttons).
* Moved some more space variables into Style.
- drawing code cleanup
- use of BLF_font in own string drawing, needs to be aligned with uiStyles still.
- thumbnail scaling now done on graphics card via new glaDrawPixelsTexScaled (slightly modified glaDrawPixelsTex)
This new algorithm groups F-Curves into groups of 3-4 with similar colours, since triplets of related settings are more likely to be encountered.
The colours get darker down the list. Blocks of related F-Curves will alternate between being boldly and weakly shaded.
I've left the old method still there but commented out. This new method could still be improved, as some of the colours chosen don't really stand out that well IMO.
Testing and suggestions welcome as always :)
After quite a bit of searching, I finally found where the various UI functions were wrapped for use in Py Layouts.
For the reference of others, check out editors/interface/interface_api.c
Now properties in nested structs should be able to be keyframed (i.e. AO in World, and SSS in Materials). Added an extra method to RNA for this to work.
Fixed one of the causes of keyframes not being able to be inserted. For ID-types where inheritence of the basic wrapping of the struct (i.e. for Lamp blocks, shadow and other lamp-type specific settings were only defined in subclasses of the Lamp struct), the RNA_id_pointer_create() function now performs additional refinement of the PointerRNA so that the pointer will be resolved correctly to allow access to these settings.
The other case which is unresolved for now is nestled structs. The RNA_path_from_ID_to_property() needs modification for this, but dunno how yet.
*Added initial material buttons (Material Color, Ray Transparency, Ray Mirror, Subsurface Scattering)
Only works for default material atm.
*some layout tweaks to the lamp panels.
Fonts like Type 1, have one file with the glyph image and another
file with metrics and kerning information, this try to search if the font
have this information and load (try open the same file but with the .afm
and .pfm extension).
Also add a function to load the same information from memory, just in case
that in some point we add a font like this.
Now that we only work with Freetype2, I don't see any point to keep
wrapping the functions.
Also remove the reference code, it's something that we don't go to used.
* Split the buttons_data.py into separate files, this makes it easier to maintain them.
Notes: Added an extra modifier file, because modifiers are for different object types.
* Added basic lamp buttons and Sun/Sky settings.
As the camera buttons they only work for the default light object for now.
* Some minor code cleanup
* Replaced a few duplicated enums that were also defined for some RNA properties already with the RNA ones.
* Start of cleanup of markers code in preparation for getting the rest of the editing code involving markers working again
1) Remove WITH_FREETYPE2 from code, so now blender always need freetype2
2) Remove the old bmfont
3) Remove ftfont and bFTGL library
4) Implement a new BLF_draw_default function for place that still need/use
the old BMF api.
I try to update both, scons and cmake, but I only can test with make, so
hope all work fine.
MSVC is broken, but I don't have Windows, things to search and fix are
any reference to WITH_FREETYPE2, FTGL and BMFONT (take in care that
blenkernel also have a BKE_bmfont.h, this don't have anything to do with bmfont).
Always have to link/include the freetype2 library
Remove any reference to libbmfont
Remove any reference to libftfont
Remove any reference to libbftgl (or libbFTGL)
* Added 'Replace Keyframes' entry that appears in addition to delete, since it is often useful to be able to directly replace values instead of having to delete and reinsert keyframes. Internally, this just calls the Insert Keyframe operator.
* Separated the code to for Driver editing from the tests for keyframes, since they're independent.
* Added separators between keyframe and driver operations. This could be removed if the UI-mafia consider it overkill.
* Added camera buttons.
* Added poll to check on active object type.
ToDo:
* Lens Unit "lens" and "angle" don't update each other. Needs RNA fix.
* Buttons only work for default camera now, needs better context.
* Loading files saved with 2.5 works again now without crashing. Was crashing when trying to load Grease Pencil data (even though there was none)
* Fixed some msvc compiler warnings in own code
Time-Modifying F-Curve Modifiers now get special callbacks to allow them to specify what frame they need to be evaluated on, instead of forcing a re-evaluation of the preceeding curve + modifier-stack. This should be more robust than the old way in general.
It still remains to be seen if some tweaks to this are still needed, as the full consequences of the propogation of modified time-spaces have yet to be fully explored.
For now though, evaluation works by finding the last modifier on the stack which modifies time, and asks it what time it modifies the given time to. This modified time is used to evaluate the F-Curve data only. The modifier stack gets evaluated using the original time instead.
