This modules does not depend on any blender-specific data
structures or algorithms and due to our policy better be
placed to intern/
Shall be no functional changes, tested CMake and SCons on
Linux, hopefully other platforms will work as well.
P.S. SVN history shall be preserved for the files.
This means you can for example, uv unwrap in quad-view and change settings in the toolbar without defaulting back to the first quad-view region available.
This may be displayed to the user later, for now this is set on executing registrable operators.
Issue was caused by storing BB calculated from final displist in
Curve datablock and not having Object's BB at all. This is not
clear at how could have been worked for so long.
Changed it so Curve's BB is calculated from non-deformed displist,
which matches BKE_object_min_max and BKE_curve_texspace_calc and
made it so Object's BB would be calculated from final displist.
Change Scene.frame_set so that it ensures subframe in range [0,1[ as Blender
expects, otherwise some things like physics point cache lookups don't get
evaluated properly.
- The "ID" buttons (for browse images, for example) now show a Pack icon, for packed
Images. Using this button allows unpack.
- Pack and unpack operations now give a Info report on what happened.
- Not restored yet: option to set "AutoPack".
Was silly mistake from rigidbody merge, base was used after it's been
freed.
Now don't free base in BKE_scene_base_remove() and rename it to
BKE_scene_base_unlink().
Issue was caused by FILE multilayer ImBuf sharing buffers with render
result, and SEQUENCE multilayer ImBufs duplicating buffers. Which is
nice by it's own. But, changing image source wouldn't remove any loaded
image buffers, meaning if you've got loaded FILE multilayers they'll
likely became invalid.
That behavior of handling multilayers on changing source was done as
a fix for #24976, which is now actually not needed (removing check
for multilayer doesn't change behavior at all).
Just to be sure added check to RNA, so signal wouldn't be fired if
source wasn't actually changed form a menu.
- Cycles materials now render in Blender Internal too, skipping the nodes.
Not very useful, but at least things then show up on renders and in
previews.
- Node editor: if wrong shader nodes are in a tree, they draw with thene
color RED ALERT headers now. (Switching render engine will show it).
This means the deformation on the input to the modifier can be re-applied ontop of the mesh cache.
In practice this is most useful for using corrective shape-keys with mesh-cache.
BKE_rigidbody_aftertrans_update() can be called before rigid body is
validated so check before updating physics_object.
Thanks to Antony Riakiotakis (psy-fi) for the initial patch.
This allows moving rigid bodies on frame > startframe.
Also rigid bodies can now be picked up and trown around while the
simulation is running.
Note: There is a small glitch with cancelling tansform during simulation
but it's tricky to get rid of.
TODO: Avoid static-static collision warnings
Behaves like the generic constraint but has optional spring on each axis.
TODO: Add option to set rest length.
Patch by Markus Kasten (markus111), thanks!
Constraints connect two rigid bodies.
Depending on which constraint is used different degrees of freedom
are limited, e.g. a hinge constraint only allows the objects to rotate
around a common axis.
Constraints are implemented as individual objects and bahave similar to
rigid bodies in terms of adding/removing/validating.
The position and orientation of the constraint object is the pivot point
of the constraint.
Constraints have their own group in the rigid body world.
To make connecting rigid bodies easier, there is a "Connect" operator that
creates an empty objects with a rigid body constraint connecting the selected
objects to active.
Currently the following constraints are implemented:
* Fixed
* Point
* Hinge
* Slider
* Piston
* Generic
Note: constraint limits aren't animatable yet).
Add operators to add/remove rigid body world and objects.
Add UI scripts.
The rigid body simulation works on scene level and overrides the
position/orientation of rigid bodies when active.
It does not deform meshes or generate data so there is no modifier.
Usage:
* Add rigid body world in the scene tab
* Create a group
* Add objects to the group
* Assign group to the rigid body world
* Play animation
For convenience the rigid body tools operators in the tools panel of the 3d view
will add a world, group and add objects to the group automatically so you only have
to press one button to add/remove rigid bodies to the simulation.

Add read/write/interpolate functions.
In order to get rigid body point cache id from object it's now required to pass the
scene to BKE_ptcache_ids_from_object().
Rigid body cache is drawn in the orange color of the bullet logo.
Force fields work with rigid bodies just like they do with other simulations.
Increase min and max strength of force fields so they can influence heavy rigid
bodies.
TODO: Adjust force field strength based on the time step taken.

This is just the basic structure, the simulation isn't hooked up yet.
Scenes get a pointer to a rigid body world that holds rigid body objects.
Objects get a pointer to a rigdid body object.
Both rigid body world and objects aren't used directly in the simulation
and only hold information to create the actual physics objects.
Physics objects are created when rigid body objects are validated.
In order to keep blender and bullet objects in sync care has to be taken
to either call appropriate set functions or flag objects for validation.

Currently used special checks in DM draw code, perhaps better would be
simply to flush changes from PBVH to DM.
Anyway, now things seems to be working OK, will check on better solution
from code point of view later.
Full log is here:
http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.66/Usability#Matcap_in_3D_viewport
Implementation notes:
- Matcaps are an extension of Solid draw mode, and don't show in other drawmodes.
(It's mostly intended to aid modeling/sculpt)
- By design, Matcaps are a UI feature, and only stored locally for the UI itself, and
won't affect rendering or materials.
- Currently a set of 16 (GPL licensed) Matcaps have been compiled into Blender.
It doesn't take memory or cpu time, until you use it.
- Brush Icons and Matcaps use same code now, and only get generated/allocated on
actually using it (instead of on startup).
- The current set might get new or different images still, based on user feedback.
- Matcap images are 512x512 pixels, so each image takes 1 Mb memory. Unused matcaps get
freed immediately. The Matcap icon previews (128x128 pixels) stay in memory.
- Loading own matcap image files will be added later. That needs design and code work
to get it stable and memory-friendly.
- The GLSL code uses the ID PreviewImage for matcaps. I tested it using the existing
Material previews, which has its limits... especially for textured previews the
normal-mapped matcap won't look good.
It was caused by own mistake by not noticing externtex is used not
only by render engine. Now this function uses pool passed as argument
rather than using R.pool.
It was caused by image threading safe commit and it was noticeable
only on really multi-core CPU (like dual-socket Xeon stations), was
not visible on core i7 machine.
The reason of slowdown was spinlock around image buffer referencing,
which lead to lots of cores waiting for single core and using image
buffer after it was referenced was not so much longer than doing
reference itself.
The most clear solution here seemed to be introducing Image Pool
which will contain list of loaded and referenced image buffers, so
all threads could skip lock if the pool is used for reading only.
Lock only needed in cases when buffer for requested image user is
missing in the pool. This lock will happen only once per image so
overall amount of locks is much less that it was before.
To operate with pool:
- BKE_image_pool_new() creates new pool
- BKE_image_pool_free() destroys pool and dereferences all image
buffers which were loaded to it
- BKE_image_pool_acquire_ibuf() returns image buffer for given
image and user. Pool could be NULL and in this case fallback to
BKE_image_acquire_ibuf will happen.
This helps to avoid lots to if(poll) checks in image sampling
code.
- BKE_image_pool_release_ibuf releases image buffer. In fact, it
will only do something if pool is NULL, in all other case it'll
equal to DoNothing operation.
to draw with procedural textures on surface of object. 2D painting will
still paint as if tiled.
When we unify the paint systems, the texture sampling functions will
need to be changed. Sculpt uses a slightly different system that passes
both screen and 3d coordinates to the sampling function. This commit
however is not too disrupting for that however so it can go in now.
