Object.is_modified(scene, 'PREVIEW') function for python exporters to check if any modifiers or shape keys are applied (weather the original mesh can be used for exporters).
Also use const char in many other parts of blenders code.
Currently this gives warnings for setting operator id, label and description since these are an exception and allocated beforehand.
- object updates were not being flushed, so children weren't updating.
- apply the matrix relative to the parent, added this as an option to object_apply_mat4() which allows assigning the worldspace matrix in python without worrying about the parent.
- removed deprecated bitmap arg from IMB_allocImBuf (plugins will need updating).
- mostly tagged UNUSED() since some of these functions look like they may need to have the arguments used later.
- the length of a new text object wasnt set on creation.
- tex3d and controllers rna name was being set to its body (rather then ID name)
- remove reference to wave objects which are very old and not used anymore.
This commit restores fluid sim baking functionality in 2.5, it's been on the todo for
a while, and was previously almost completely non-functional. The old
code was quite complicated and specific to the 2.4 animation system, so I've
pretty much rewritten most of it.
This includes:
* Animated variables work again - just key them in the UI. Non-animateable values
should be already set non-animateable in RNA, hopefully I got them all.
Available are: Domain Gravity / Domain Viscosity / Object loc/rot/scale /
Object initial velocity / Deforming meshes / Fluid control Attract strength /
Fluid control Attract radius / Fluid control Velocity strength /
Fluid control Velocity radius / Object Active status (checkbox next to fluid type)
The Domain time scale is still not yet implemented.
* Fluid sim now use global scene units data by default - when enabled, the
scene's global gravity value is used and when units are set (metric/imperial)
the simulation real world size is taken from the object's actual measurements.
* The baking process is now done in the background, using the nifty threaded
Jobs system. It's non-blocking and your domain object will show the simulated
fluid as it becomes available for that frame.
A nice extra thing for the future would be to improve the visualisation of the
object's state while baking, and also the jobs system/ui could do with some
touchups - currently it has to share a bit from the 'render' job, and appears as
'Render' in the header. Progress bars for jobs in the header would be great too.
- Camera to 3D view didnt check for rotation order.
- Fly mode didnt check for rotation order.
added util functions.
- object_apply_mat4(ob, mat4); applies a 4x4 matrix to an objects loc,scale,rot (accounting for rotation modes)
- object_mat3_to_rot(ob, mat3, use_compat); apply a 3x3 matrix to the objects rotation, option to use a euler compatible with the existing euler.
* template_modifier creates the modifier box, and returns a layout
to put the buttons in.
* Only the armature modifier is now done with python code, all other
modifiers use C code. To convert a modifier to python, remove the
corresponding C code and create a function in DATA_PT_modifiers.
* Some modifiers still require some RNA work to get it working well,
especially to make pointers editable. Mostly that is a matter of
defining an own _set callback and put some of the modifier C code
into it.
* Still various buttons that don't work, like for hooks or mesh
deform binding.
* Fix for crashing decimate modifier (still disabled).
* Removed UI_BUT_NO_HILITE, HMENU.
* Make uiLayoutBox work with align.
Put back Armature/Pose code, including 'heat weight'.
I've added reeb.h to get things compile, but Martin will
cleanup files and put back?
Now where to put all vertexgroup code.... I guess mesh?
Note for msvc: yep, another new dir to add! :)
Think global, act local!
The old favorite G.scene gone! Man... that took almost 2 days.
Also removed G.curscreen and G.edbo.
Not everything could get solved; here's some notes.
- modifiers now store current scene in ModifierData. This is not
meant for permanent, but it can probably stick there until we
cleaned the anim system and depsgraph to cope better with
timing issues.
- Game engine G.scene should become an argument for staring it.
Didn't solve this yet.
- Texture nodes should get scene cfra, but the current implementation
is too tightly wrapped to do it easily.
(partial because I'll merge all snap code in one fell swoop after the libs are done)
----------------------------------
object: ray - boundbox intersection test
bsystem_time was being called with an extra variable, which was useless. Most of the places that called it, were passing NULL for that variable anyway.
I've also cleaned up that function a bit, but the underlying problems with that part of the code still exist (EVIL GLOBALS that are exported for frame_to_float), for mblur and fields rendering features. That remains for another time.
After just over a week of coding, I've finished doing a major refactor/cleanup of the constraints code. In the process, quite a few old kludges and ugly hacks have been removed. Also, some new features which will greatly benefit riggers have been implemented.
=== What's New ===
* The long-awaited ``ChildOf Constraint'':
This allows you to animate parent influences, and choose which transformation channels the parent affects the child on (i.e. no translation/rotation/scaling). It should be noted that disabling some combinations may not totally work as expected. Also, the 'Set Inverse' and 'Clear Inverse' buttons at the bottom of this constraint's panel set/clear the inverse correction for the parent's effects. Use these to make the owner not stick/be glued to the parent.
* Constraint/Target Evaluation Spaces:
In some constraints, there are now 1-2 combo boxes at the bottom of their panel, which allows you to pick which `co-ordinate space' they are evaluated in. This is much more flexible than the old 'local' options for bones only were.
* Action Constraint - Loc/Rot/Size Inputs
The Action Constraint can finally use the target's location/rotation/scaling transforms as input, to control the owner of the constraint. This should work much more reliably than it used to. The target evaluation should now also be more accurate due to the new space conversion stuff.
* Transform - No longer in Crazy Space (TM)
Transforming objects/bones with constraints applied should no longer occur in Crazy Space. They are now correctly inverse-corrected. This also applies to old-style object tracking.
=== General Code Changes ===
* solve_constraints is now in constraints.c. I've removed the old `blend consecutive constraints of same type' junk, which made the code more complex than it needed to be.
* evaluate_constraint is now only passed the constraint, and two matrices. A few unused variables have been removed from here.
* A tempolary struct, bConstraintOb, is now passed to solve_constraints instead of relying on an ugly, static workobject in some cases. This works much better.
* Made the formatting of constraint code consistent
* There's a version patch for older files so that constraint settings are correctly converted to the new system. This is currently done for MajorVersion <= 244, and SubVersion < 3. I've bumped up the subversion to 3 for this purpose. However, with the imminent 2.45 release, this may need to be adjusted accordingly.
* LocEulSizeToMat4 and LocQuatSizeToMat4 now work in the order Size, Rot, Location. I've also added a few other math functions.
* Mat4BlendMat4 is now in arithb. I've modified it's method slightly, to use other arithb functions, instead of its crazy blending scheme.
* Moved some of the RigidBodyJoint constraint's code out of blenkernel, and into src. It shouldn't be setting its target in its data initialisation function based + accessing scene stuff where it was doing so.
=== Future Work ===
* Geometry to act as targets for constraints. A space has been reserved for this already.
* Tidy up UI buttons of constraints
- Dont do anything if no verts or faces are selected (used to zoom into 0,0,0)
- use the centers of dupli objects (should eventually use their bound boxes), much nicer when dealing with many dupli-objects
The first incarnation assumed that proxies were local objects per
definition. Unfortunately that makes it impossible to - for example -
reference-link an entire Scene with proxies, to be used as a special
character set.
This commit makes the proxy implementation also a bit more clear.
Related work: the scene-sets were not executed fully or correctly for
the dependency graph. That happens now (in 3d view) as well.
Vertex/Face/Frame duplication now draws using OpenGL display lists. Makes
drawing go much faster (2-5 times, depending on size of duplicated object).
This system uses boundbox checks too, so outside of view it draws faster.
Note for face duplication: I've fixe a bug for incorrect alignment when
the parent was rotated when a parenting happened, the 'inverse parent
correction matrix' then messed up alignment. For face duplication it now
works OK, but for vertex-dupli not... need a way to fix this backwards
compatible.
Notes:
- Only referenced groups (from other files)
- Only 1 group (no more duplicates using same group yet)
- Only Proxy working well for Armature or Empty
Is going to be reviewed in Plumiferos team; but target is that this will
solve a major animation pipeline bottleneck :)
Usage; select group, alt+ctrl+p, pick an object you want to proxify.
THE OBJECT PROXY
Or simple said; local control of referenced data from libraries.
Having library files with references is a very common studio setup, and
Blender did do quite well in that area. Were it not that for character
setups it was impossible to use still.
This commit will enable a full rig+character to remain in the library,
and still have - under strict control - local access for animation edits.
Full log:
http://www.blender3d.org/cms/Proxy_Objects.824.0.html
New "Dimension" button: when using TAB to cycle over buttons, the dimension
event was sent multiple times, accumulating scaling. The code was also not
prepared to handle multiple changes at one event.
Also: added object_get_boundbox(Object *ob) in BKE_object.h, so the code
now really supports most primitives in Blender.
