* This is experimental, the file format may change still!
* Helps reduce memory usage, keeps .blend files smaller, and makes
saving quicker when not editing multires.
* This is implemented at the customdata level, currently only the
multires displacements can be stored externally.
ToDo
* Better integration with object duplication/removal/..
* Memory is not yet freed when exiting sculpt mode.
* Loading only lower levels is not supported yet.
* Displacement coordinates are now stored differently, as a grid per
face corner. This means there is duplication of coordinates, especially
at low subdivision levels, but the simpler implementation justifies it
I think.
* ToDo: conversion of existing multires files (2.4x or 2.5x), loading them
may even crash now.
* Editmode preservation/interpolation code also has not been updated yet.
* Multires now works on the CCGDerivedMesh grids instead of CDDerivedMesh,
which should be more memory efficient.
* There are still bad memory peaks (if you're using 32bit) when subdividing
or propagating displacements. Though at least there should be no huge
memory blocks allocated, which windows is now to have trouble with.
* Still found some weird spike artifacts at lower multires levels, some also
happening before this commit. Perhaps computation of tangents needs to be
tweaked more.
* Multires modifier now has viewport, sculpt and render levels. Also the
levels have been made consistent with subsurf, previously the same level
of subdivision was one less for multires.
* Both multires and subsurf modifier now can have their subdivision level
set to 0 for no subdivision.
* PBVH can now be created contain both from face grids or standard
meshes. The former is much quicker to build for high res meshes.
* Moved some drawing code into pbvh (mostly for the frustum test).
* Moved ray intersection code into pbvh.
* GPU buffers also can be built from either mesh or grids now.
* Updated sculpt code to work with this. The ugly part is that there
is now a macro for iterating over vertices, to handle both cases,
and some duplicated code for e.g. undo.
* Smooth brush does not work yet with grids.
* Now uses the CCG DerivedMesh also in object mode, used to be edit mode only.
* Create CD_ORIGINDEX layer on demand, to save memory.
* Removed ss_to_cdderivedmesh function, and instead create ccgdm and then
convert that to cddm, to avoid code duplication.
* Added and implement DerivedMesh interface functions to obtain face grids.
* Store edge/face flags more memory efficient.
* Export CCGDerivedMesh struct in BKE_subsurf.h
The Animation System now respects the Transform Locks too (i.e. lock x-location, etc.) when writing settings. This means that it is no longer necessary to set up "constant drivers" to make sure some values don't get accidentally animated.
Internally, added a new callback for properties in RNA, which is responsible for checking if the item at some array-index is editable. This needs to be manually called for each place which uses rna to set settings for arrays (see the code changes in anim_sys.c for changes how to do this; the same thing needs to be done in the UI code too, and probably in py-api too)
* Fixed a few compile warnings for scons+mingw
* Driver variables are now added with the ID-type set to ID_OB (objects) by default since this is more convenient
Even a static mesh can be used as replacement: the mesh
will be instantiated with the soft body settings of the
object. The position and orientation of the soft body
is preserved after the replacement.
Known limitation: the velocity of the soft body is reset
aftet the replacement. This is because soft body don't
have a well defined velocity.
* Removed ED_anim_dag_flush_update and ED_anim_object_flush_update. These
were wrapping DAG_* calls and were intended be used instead of them when
doing a DAG update from editors. That goes against the design in my opinion,
no matter who calls the DAG, that should update the editors correctly, so
any special checks in such functions for editors should be avoided.
* Driver RNA properties now do updates again, including DAG scene sorting,
text buttons no longer update as you type anymore, so this should be
safe I think.
* Remove scene.update() RNA function, all properties/functions should do this
automatically, if changing some property or calling a function/operator
does not do the correct update, that should be fixed.
Reshuffled the code a bit so that the parent-type gets set before the parent inverse matrices are calculated.
Thanks to Claas Eicke Kuhnen (cekuhnen) on Blender Artists for catching this.
* Insert Keyframe (IKEY) now only shows the menu requesting to choose a KeyingSet to use if there is no active KeyingSet. To get the old behaviour, the "always_prompt" boolean property for the "ANIM_OT_insert_keyframe_menu" operator should be supplied.
* After inserting/deleting keyframes without the menu, a popup menu confirming that the keyframes have been modified is shown. Please note that you do not need to click on this popup.
TODO:
Make the confirmation popup fade out after a fixed time.
This means you can have a pose bone for eg and get the path...
pose.bones["Bone"]
uses rna internal functions, so will work for sequence strips etc.
- StructRNA.get(), used for getting ID props without exceptions...
val = C.object["someKey"]
or..
val = C.object.get("someKey", "defaultValue") # wont raise an error
- change rna property for testing if rna props are editable, test the flag rather then calling the function since the function depends on blenders state.
- fix a python exception with the ID-Property popup UI (when editing in more then 1 step)
duplicate_pose_channel_data(), the code to do this was inline in editarmature.c
duplicating editbones now duplicates posebone id-props
also removed an if test for &channew->constraints since it will always be true.
fixes a crash that happens when formatting a python exception into a report. - for now use pythons string formatting function.
happens when running the simple operator template so not sure if its worth re-tagging :S
Leftmouse+Ctrl to extrude now mapped to Click instead of Release. Release was used to avoid conflict with lasso, but it isn't safe with modal operators that use Press to confirm (subsequent Release then extruded). Click is semantically closer to what we want here.
