- remove falloff setting now the curve is used.
- bugfix for airbrush & tablet, with no movement it would assume 1.0 pressure.
- rna, use the use_* prefix for brush options.
* Changed the non-projection paint code to use the brush falloff curve, rather than a predefined falloff. This makes non-projection painting in the 3d view, and image editor painting much more consistent with other brush usage.
New stuff
- Bending springs for hair dynamics.
Code cleanup & optimization
- Disabled reactor particles temporarily for cleanup, it's a clumsy system that will be replaced with something better.
- Removed child seams, something better will come here too :)
- Normal particle drawing data is now saved between redraws if the particles don't move between redraws.
* For example rotating the 3d view is now realtime even with 1M particles.
- Many random values for particles now come from a lookup table making things much faster.
- Most accessed small point cache functions are now much faster as macros.
- Lot's of general code cleanup.
- Nothing big should have changed so if something doesn't work like it used to it's probably just a typo somewhere :)
Note sure what to do with this one, and personally think
we should avoid using macros for this kind of thing:
V_GROW(edges);
source/blender/editors/mesh/loopcut.c:232: warning: value computed is not used
Added a utility function to check which transforms for an object or bone are animated, returning these as bitflags and/or optionally retrieving the relevant F-Curves too. Beware that this method may not be working correctly yet, but it shouldn't hurt anyone in the meantime :)
Also, split RNA-path building function up into a version which only creates the path up to the given struct, with the other parts being added later.
* The image panels in the image editor and texture buttons
should be more complete now, with working new/open,
refreshes, and using the layout engine.
* Paint panels in image editor are now consistent with the
ones in the 3d view toolbar.
* Curves panel also uses layout engine, and doesn't look
squashed anymore.
writes all operators (including PyOperators) and their default values into a textblock.
Useful for an overview and checking consistancy.
eg. http://www.pasteall.org/7918/python
added rna functions text.clear() and text.write(str)
#19345: can't get out of grayed out pointer field.
#19342: item_pointerR fields can't be cleared with one item.
#19341: fix hanging tooltips when manipulating regions.
#19339: context panel still allowed tabbing, but it has no header.
#19334: editing SSS settings crashed previewrender.
#19330: object mode could not be switched on from the header menu.
* Added separate menu items for Link and Append.
* Change some OPERATOR_FINISHED to OPERATOR_CANCELLED.
* Remove some IPO specific hacks, these are no longer ID blocks,
so not necessary to take into account.
* Some comment and code formatting tweaks.
* Move function to compute visible screen layers to BKE.
* Use this now in the depsgraph, was still using this all layers
to flush. Still missing a way to get the current scene in
background mode..
* Also two more function to not require a scene pointer anymore:
* DAG_object_update_flags is now DAG_id_update_flags.
* DAG_ids_flush_update is now available next to DAG_scene_flush_update.
* Totally new try to get cache running
* Didn't try "bake" and such things yet
Hint
* Very verbose yet
* Please do only test new blend files, not old ones!
Please give me feedback on my blog about the old crashers.
Appending and Linking
* Linking Operator, invokes filebrowser for Append/Link
* Separated the append/link function into three parts:
** BLO_library_append_begin finds main for appending
** BLO_library_append_named_part appends one Object,Group, Material, ...
** BLO_library_append_end actually reads and expands the libraries
NOTE 1:
I also changed the returned properties for the filebrowser operators to the following convention:
"path" - the full path to a file or directory, means what is in directory + filename buttons in filebrowser
"directory" - the content of the directory button in filebrowser
"filename" - the content of the filename button in filebrowser
Usually only path should be required, but in some cases it might be more convenient to retrieve the parts separately.
Ton, Brecht: If you have time to take a look, let me know if anything needs to be fixed.
- use_radius option, off by default for 2.4x files, on by default on new curves.
- curve deform modifiers (think tentacles)
- follow path (parent mode and constraint)
- curve guides
- added back Alt+S to scale point radius
- Mat3Scale and Mat4Scale arithb.c functions to make a new uniform scale matrix.
- TODO, effectors, looks like they have no way to scale from the radius yet.
* Added a few new methods for axis-angle conversions, and used these instead of manually performing those steps elsewhere
* Axis-angles to other representations now get their axes normalised to make sure that odd scaling doesn't occur.
* Made a few more tools work with axis-angles properly
* added new twist method - "Tangent", suggested by Martin.
the nice thing about this is its stable no matter how you rotate the data, rotation is local to each segment.
* added smooth option that smooths the twisting (before applying user twist), to workaround Z-Up and Tangent's ugly curve twisting. Id prefer not to have this however it makes tangent much nicer. Possibly tangent can be improved some other way and this can be removed.
A smooth value of 1.0 will iterate over and smooth the twisting by the resolution value of the spline.
* Minimum-Twist method now corrects for cyclic twist by taking the roll difference between first and last, then increasingly counter rotate each segment over the entire curve. Previously it calculated from both directions and blended them.
details
* BevPoints use quats rather then 3x3 matrix.
* added BevPoint direction "dir" and tangent "tan" used only for 3D curves.
* don't calculate BevPoint->cosa, BevPoint->sina for 3D curves.
* split bevel tilt calculation into functions.
* nurbs curves currently don't generate tangents and wont work with tangent twist method.
* some of the use of quats should be optimized.
* smoothing is not animation safe, the higher the smoothing the higher the likelyhood of flipping.
The support for this is really quite hacky, and I might disable this later if we cannot get some parts to work nicely.
Some notes:
* This is currently stored in the same variable that quaternions are stored in, since they both have 4 components. However, in RNA, I've added 2 properties specially for this.
* There are some shearing issues using certain axes - i.e. (1,1,0) - that will need to be checked on.
* Transform code is really quite temporary for this. Just a quick demo of what can be done...
- Hair dynamics have their own panel in particle settings with the settings from cloth panel that apply to hair.
- Basic internal friction force to quickly emulate self collisions and volume preservation. (Still very early code, but gives some idea of what's possible).
- Softbody simulation is no longer used for hair.
* Old files with sb dynamics should just load the hair without dynamics so new dynamics can be applied.
* Invasion of particles exceptions in sb code is finally over.
- Collisions with other objects are disabled for now and will be worked out in the future.
Other changes/fixes:
- Particle mode editing flag wasn't saved properly.
- Some old files with edited hair didn't load correctly.
- Disabled delete & specials menu in particle mode for non-hair editing.
- Fixed yet one more cloth & softbody pointcache update issue.
- Disconnect/connect hair now uses only the deformed mesh so it works correctly also for subsurfed emitters.
- Hair editing now updates correctly with a moving emitter.
Added RGB space distance matte Node
Added HSV color matte Node
Fixed Image difference matte Node to use image differences instead of RGB space distance
Fixed luminance node for low end values being read wrong
Fixed CMP_util copy/swap functions not accounting for all channels
Fixed UI for difference matte Node
Added RNA for new nodes
Renamed BevPoint's members
* x,y,z -> vec[3]; compatible with other functions.
* f1 -> split_tag; used by displist to set the splitting flag.
* f2 -> dupe_tag; used in curve.c to remove duplicates.
BevList
* flag -> dupe_nr; was being used as a counter for duplicate points.
* use arithb.c functions where possible.
* arrays for coords, tilt and radius were being allocated, then copied into the BevPoint's, now write directly into the values without allocing/freeing arrays.
* Enable cache for high res + new preview
* Bugfix for smoke banding (in cooperation with N_T)
Hint: Work-in-progress regarding collision objects so can be broken, didn't test
Hint2: jahka enabled a general particle panel but
* bake button doesn't work
* step is not supported for cloth
* several other things there ;)
* Split object_edit.c into multiple files:
object_add.c, object_edit.c, object_hook.c, object_relations.c,
object_select.c, object_transform.c.
* Rename files to have consistent object_ and mball_ prefix:
object_shapekey.c, object_lattice.c, object_vgroup.c, mball_edit.c.
* Added operators:
* vertex group menu and set active
* apply location, rotation, scale, visual transform (location is new)
* make local
* make vertex parent
* move to layer
* convert to curve/mesh (not finished yet)
* Many small fixes for marked issues, but still much code to be cleaned
