* support for dynamic enums to be inspected enumProp.items() from python.
* fix, enums check for a separator was flipped, meant no enums were in docs.
* dynamic enum functions now check for a NULL context and return all possible options for the "items" attribute used for docs.
* added an arg for rna arrays to free the array there looping over (needed to free dynamically allocated enum items)
* python api checks for NULL items since this can happen in some cases.
* python api, When getting an enum ID from an int in an array - If it failed it would get the first enum identifier and return that. Brecht? dont understand, making it return an empty string in these cases.
- Keyed targets in one list instead of "chaining", this opens up many more possibilities than before and is much less obscure.
- Better keyed timing possibilities (time & duration in frames).
- Looping over keyed targets list.
Other changes:
- New child setting "length" with threshold (great for guard & underfur with a single particle system)
- Modularization of path interpolation code.
- Cleared "animateable" flags from many particle settings that shouldn't be animateable.
Fixes:
- Keyed particles weren't copied properly (ancient bug).
- Hair rotations depended on global z-axis for root rotation so downward facing strands could flip rotation randomly. Now initial hair rotation is derived from face dependent hair matrix. (This caused for example ugly flipping of child strands on some cases).
- Children from faces weren't calculated straight after activating them.
- Multiple disk cache fixes:
* Disk cache didn't work correctly with frame steps.
* Conversion from memory cache to disk cache didn't work with cloth.
* Disk cache crashed on some frames trying to close an already closed cache file.
* Trails didn't work with disk cached particles.
- Child rough effects were effected by emitter object loc/rot making them next to useless with animation, why didn't anybody tell me this!!
- Lots of random code cleanup.
* Enums can now be dynamically created in the _itemf callback,
using RNA_enum_item(s)_add, RNA_enum_item_end. All places asking
for enum items now need to potentially free the items.
* This callback now also gets context, this was added specifically
for operators. This doesn't fit design well at all, needed to do
some ugly hacks, but can't find a good solution at the moment.
* All enums must have a default list of items too, even with an
_itemf callback, for docs and fallback in case there is no context.
* Used by MESH_OT_merge, MESH_OT_select_similar, TFM_OT_select_orientation.
* Also changes some operator properties that were enums to booleas
(unselected, deselect), to make them consistent with other ops.
* Weight paint: brush strength was changed to both define weight
and strength, this can't work, made them separate buttons.
* Allow adding particle system as modifier (fix crash).
* 3D view modal ops (zoom ..) could not be ended when invoked
from a button.
* Fix some warnings.
* Fix spelling in particle RNA property.
This commit is quite experimental, and might have to be reverted, but in quite a few places, the cleanups from this commit were already necessary.
* I've left most of the image-handling functions alone, since I'm not sure how well they cope with negative indices.
* Start/End frames cannot be negative for now... any specific reasons why they should be negative?
* Baked normal particles can now use the "Path" visualization.
* Path "max length" & "abs length" are now history:
- New option to set path start & end times + random variation to length.
- Much more flexible (and calculated better) than previous options.
- This works with parents, children, hair & normal particles unlike old length option.
- Only known issue for now is that children from faces don't get calculated correctly when using path start time.
* New option "trails" for "halo", "line" and "billboard" visualizations:
- Draws user controllable number of particle instances along particles path backwards from current position.
- Works with children too for cool/weird visualizations that weren't possible before.
* Normal particle children's velocities are now approximated better when needed so that "line" visualization trails will look nice.
* New particle instance modifier options:
- "path"-option works better and has controllable (max)position along path (with random variation possible).
- "keep shape"-option for hair, keyed, or baked particles allows to place the instances to a single point (with random variation possible) along particle path.
- "axis" option to make rotation handling better (still not perfect, but will have to do for now).
Some fixes & cleanup done along the way:
* Random path length didn't work for non-child particles.
* Cached & unborn particles weren't reset to emit locations.
* Particle numbers weren't drawn in the correct place.
* Setting proper render & draw visualizations was lost somewhere when initializing new particle settings.
* Changing child mode wasn't working correctly.
* Some cleanup & modularization of particle child effector code and particle drawing & rendering code.
* Object & group visualizations didn't work.
* Child simplification didn't work.
* Adding/removing particle systems to an object.
* Changing of particle settings.
* Currently showing an object's particle systems in a list (like materials).
Added AnimData to ParticleSettings so that this will work. This seems to be ok in the brief tests I did, but be warned that this may not be optimal for the Particles System...
* Allows moving, rotating & scaling of particle simulations.
* Setting in particle render options.
* Changes viewed & rendered particles from global space to parent space.
* Doesn't effect simulations at all.
* Particles support larger than 1 frame changes, bigger frame changes can result in inaccurate results, but it's super fast and you get a nice feeling of how the particles behave!
* "Cache to current frame" button calculates the exact result of particles at current frame.
* Current state of cache can be protected by making it a bake.
* Cache is now in memory by default, disk cache is an option.
* Only "viewport %" number of particles are calculated and cached in viewport, baking and rendering calculate all particles.
* Info on cached frames and memory usage given in ui.
* Support for exact "autocaching" of changes and large frame changes(disabled for now until exact place in event system is decided)
* "Continue physics" is probably deprecated after this and should be removed once sb & cloth use the new cache code.
Todo:
* Make softbody & cloth use the new cache things.
Other changes:
* Some cleanup of particle buttons.
* Added icon to property and enum property items. The latter is
responsible for the large number of files changed.
* For RNA functions, added PROP_RNAPTR flag to ask for a PointerRNA
as argument instead of a C pointer, instead of doing it implicitly
with the AnyType type.
* Material: properly wrap diffuse/specular param variables, and
rename some things for consistency.
* MaterialTextureSlot: added "enabled" property (ma->septex).
* Image: make animated property editable.
* Image Editor: make some things editable, notifiers, respect state.
* Context: fix issue with screen not being set as ID.
* Accept None as NULL pointers through python function calls.
* Added type callback for pointers back, it's useful still in
some cases. Made Object.data editable using this, the pointer
type varying based on object type.
* Wrap pin ID pointer in buttons space.
* Added subclasses for text and surface curve ID blocks, to
organize data better and get proper icons.
* Added RNA_type_to_ID_code and ID_code_to_RNA_type functions.
* Update RNA_access.h with new RNA types.
-Many things not yet working properly :)
-Experimental new (hopefully more logical) categorization of buttons, feedback on this is very welcome.
-Separate render & draw types, for example now there is actually a render option "halo" instead of all the different point draw types.
-Particles get recalculated only from buttons that actually change something that has to be recalculated, for example changing visualization doesn't reset particles any more.
-Boid physics buttons are still missing as I'm currently redoing the whole boids code.
-Point caching is still very wip, so baking is not possible for example, but I added a few cache baking flags for rna that were/will be needed for particle buttons logic.
* Added a MaterialSlot collection in Object rather than giving
the list of materials immediately. This should more correctly
reflect how this data is organized, even though there is no
equivalent C struct.
* Added name properties to MaterialSlot/TextureSlot/ParticleSystem.
* Automatically do us++ and us-- reference counting in ID pointer
set functions.
* Added an enum property callback to dynamically vary the list of
available items.
* Added some functions to do removes on pointers and collections
runtime defined for RNA and using ID properties.
* Constraints now have owner/target space wrapped, and most
pointers made editable. They can be ported to use python layouts.
* Also other pointers made editable that I think are see now with
the automatic reference counting.
* Allow pointers to be editable, did SpaceTextEditor.text as a test.
* Changed PROP_NOT_EDITABLE to PROP_EDITABLE, and added
RNA_def_property_clear_flag.
* Removed rna_dependency.c test code.
* Added Particle wrapping patch by Roelf de Kock. It's not
complete yet and I haven't reviewed it, but committing anyway,
will get to it later.
* Added "Percentage" subtype for floats. Doesn't really do
much besides making auto rna buttons into sliders rather than
numeric inputs, but can later display in % rather than 0.0-1.0.
* Finished DNA_lamp_types.h, DNA_world_types.h and DNA_sound_types.h.
* Renamed "parent" struct property to "nested", and also remaining "from"
usage to "base".
* Added a NEVER_NULL subtype for pointers and use it for all properties
that apply.
* Make sure all structs have a description, and fix any other DOC_BROKEN
descriptions, also many other naming consistency improvements.
