* Adding/removing particle systems to an object.
* Changing of particle settings.
* Currently showing an object's particle systems in a list (like materials).
* Based on what happens during simulation the cache is marked (also in cache panel, this could possibly be extended to 3d view as well) as:
- exact (not marked)
- outdated (simulation is not done completely with current settings)
- non-exact (frames were skipped during simulation)
* The parameter "cache step" effects the number of frames between saved cache frames.
- This can save a lot of memory (or disk space) if absolutely frame accurate simulation is not required.
- Speeds up the "quick caching" very much.
- Frames between cached frames are interpolated from the cached frames.
- Current default value of 10 frames works nicely with up/down-arrows (skip 10 frames forwards/backwards on timeline), but can be changed if wanted.
* The caching can work in normal or "quick" mode:
[Normal cache]
- Basic: Calculate what even happens (settings change, big frame steps etc.) and cache results, if possible try to use "cache step" when saving cache frames.
- Becomes non-exact: After larger than 1 frame steps.
- Becomes outdated: After any change effecting the simulation other than frame steps.
- Pros/cons: Freedom of doing anything and playing with particles, but exact results have to calculated from the beginning.
[Quick cache]
- Basic: Calculate simulation up to current frame automatically on changes with cache step sized jumps in simulation. With multiple "quick cached" simulations the smallest cache step is used.
- Becomes non-exact: Always from frame 1 (unless cache step = 1).
- Becomes outdated: Never.
- Pros/cons: Not very accurate, but super fast!
- Todo: Transform of any animated (non-autokeyed) object is locked! Probably needs some tinkering with anim sys overrides.
* The simulation can be run forwards or backwards even if it's cache is outdated or non-exact, the following rules apply in these situations:
- step forwards (to unknown) -> simulate from last exact frame, store result
- step backwards (to known) -> result is interpolated from existing frames, store result, clear cache forwards if current frame is after last exact frame
* "Calculate to current frame" runs the simulation from start to current frame with a frame steps of 1.
- Baking does the same, but runs the simulation all the way to the end of simulation.
- Rendering does this automatically if the simulation is outdated of non-exact, so all rendered simulations will always be updated and exact.
* Every cache panel also holds buttons to "Bake all dynamics", "Free all dynamics" and "Update all dynamics to current frame".
* Cloth simulation supports the new cache too.
* Search popup + autocomplete for bones, vertex groups, etc. This
is done with layout.item_pointerR, specifying an RNA collection to
take the items from. Used by constraints and modifiers.
* Some tests with the List template, ignore those for now..
* Main.remove_object
* Scene.add_object
* Scene.remove_object
* Object.convert_to_triface
* Object.create_preview_mesh
- a small tweak in set_mesh (blenkernel/inter/mesh.c) to make it work on objects having data == NULL
* Added SCROLL button type, use like a NUMSLI basically, with
a1 used to define the scroller size.
* Add scroll and toggle colors to the Theme (toggle was set to
draw like radio in a recent commit, but it's the intention
these look different).
* Added rudimentary list template, used for object material
slots, this is WIP though.
* In popup menu, split text with line breaks over multiple
lines, makes python errors display slightly nicer.
- allow RNA_property_enum_items to take the totitems int pointer as NULL (spares a loop on all the enum items). this change also makes enums types with no enum array crash in some places, could support these though Id rather disallow them, generating docs is a quick way to test for this.
- open recent file operator used and enum to open the recent file without an enum array, changed to an int type.
- added space_logic.py poll functions
* Menu and header more complete now.
* Clean up Game Properties panel and moved View Properties panel
to python.
* Fix some drawing issues when combining tiles, repeat and aspect,
some also from 2.4x, these options didn't work together 100%.
* 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 optional params to Object.create_render_mesh(apply_matrix, custom_matrix)
apply_matrix is a boolean, True to transform mesh by ob->obmat or custom_matrix if given
* Fix subtle error in Object.create_dupli_list
* Make RNA struct funcs static, hopefully didn't miss any
Ignore export_obj-2.5.py changes for now ;)
Note's
* exports the mesh without modifiers or transformations applied
* supports UV's vertex colors
* no support for normals yet (missing from data api)
* registers an operator called EXPORT_OT_ply
* no file selector yet. can only fun from python currently
bpy.ops.EXPORT_OT_ply(filename="/tmp/test.ply")
* removed double lookups on the vertex dict, build face verts to write allong the way.
Updated Mathutils.Vector/Euler/Quaternion/Matrix so these are types rather then module methods, each type now has a tp_new function, matching python builtins float/int/str.
Also cleaned up float conversion and arg passing.
Changed buttons_objects.py...
if ob in groups.objects: # no longer works
if ob.name in groups.objects: # is the new syntax
...its more dict like and a lot faster (avoids python iterating over each item and comparing each, use a single rna lookup instead).
* Fix context.cloth, was not being set correct.
* Fix errors with context pinning, scripts should
not assume context.object to be there.
* Always show preview even if e.g. the material is not
set, to keep ID buttons from jumping while you're
using them.
- added export Cameras (ortho and persp) to VPORTs, incl. clipping
- added export Cameras (ortho and persp) to VIEWs, incl. clipping
- export multiple-instances of Mesh-Objects as BLOCK/INSERTs
- on start prints dxfLibrary version
* Close some material/texture panels by default.
* Update material buttons to use more diffuse/specular variables.
* Don't show texture mapping/influence when the texture is pinned.
* Small visual tweak for sequencer header menus.
* Started porting over to python, menus nearly done, header WIP.
* Game Properties panel is in python too
* Deprecated "Tiles" as a per face flag here, now it's always on
the image, used to be both, working in a very confusing way.
Unlikely someone actually had a purpose for this being per face.
* Remove GPC_PolygonMaterial.cpp/h, it's not actually used anymore,
so I don't want to bother updating it.
* Fix crash in image painting (own mistake in porting over bugfix
from 2.4x).
